With all the recent Marvel casting news, I thought it'd be interesting to write about something that takes a step in the opposite direction. The MCU is becoming MASSIVE! Just look at the picture above! Believe it or not, characters are MISSING from that picture! There are so many heroes, villains, and everything in between coming to life on the big screen today, and its awesome!
However, some characters from the comics just won't work on the big screen. No I'm not talking about X-Men or Spider-Man; this has nothing to do with different studios and who owns who. Im talking about characters that just won't translate well onto film or fit into Phase 3 for Marvel.
We already know the new characters for Phase 3, consisting of Doctor Strange, Black Panther, Captain Marvel, and a new group called the Inhumans. The Inhumans consist of various characters, such as Black Bolt, Medusa, Lockjaw, and many more. You never know who Marvel might squeeze into one of their projects. The Punisher has been rumored to pop up more than once, and its possible he'll be written into the Netflix's Daredevil series, or even into Captain America 3: Civil War.
So who WON'T Marvel show us next? While nothing is for certain, heres a few major characters in the comics that just aren't likely to grace the silver screen until at least after Phase 3:
1.) Simon Williams A.K.A. Wonder Man
A frequent member of the Avengers and other spin-off Avenger-like Teams, Wonder Man has been around since Avengers Volume 1 Issue 9, from October 1964.
Powers & Abilities:
Ionic Energy Form: The tissue and bones of his entire body have been augmented in strength and to a certain extent supplanted by an unknown substance during the "ionic ray" bombardment. Despite Wonder Man's statements that he is composed of "ionic energy," he is actually composed of organic matter that is permeated with this form of energy. Since his last revival, his physiology has changed a great deal and its not clear if his external form is ionic energy or flesh.
Superhuman Strength & Speed: Williams possesses vast superhuman strength, the limits of which aren't known. His strength extends into his legs, as he is capable of superhuman leaps covering several hundred feet. He can run and move at speeds that are beyond the physical limits of the finest human athlete.
Superhuman Stamina & Durability: Williams' ion body grants him unlimited stamina and is therefore immune to fatigue. His bodily tissues are much harder and far more resistant to physical injury than the bodily tissues of a normal human. Williams is highly resistant to penetration wounds, even from high caliber machine gun shells. He can also withstand tremendous impact forces, such as falling from great heights or being repeatedly struck by superhumanly strong opponents, without being hurt. Williams is also resistant to extremes in temperature.
Superhuman Senses: His hearing has been enhanced to a superhuman degree. Williams can also see beyond the usual spectrum visible to the human eye.
Flight: He originally required the use of a sophisticated and advanced rocket pack attached to his costume to fly. However, following his resurrection and metamorphosis, Williams is now able to fly through the air at great speeds. According to his latest official entry in the Handbooks of the Marvel Universe  Williams can fly at speeds in excess of 700 mph.
Immortality: Williams is functionally immortal. Because of the ionic energy that empowers him, he no longer ages and is immune to disease and infection. This same energy sustains Williams' physical vitality far more efficiently than the biochemical process that sustain ordinary human life. As a result, he no longer requires food, water, or oxygen.
Ionic Regenerative Healing: Williams' ionic form can heal itself from gunshot wounds, surgery, and even severed limbs. This allowed him to constantly survive death more often. This may be so because he has no bones, blood, or organs, and he is a being of pure ionic energy, allowing him to reform after any injury.
In the comics, Iron Man and Ms. Marvel recruited him into the Mighty Avengers, a team of registered super humans, following the events of the Civil War. During his time as one of the Mighty Avengers Simon began a romantic relationship with Ms. Marvel. He's also been known to date Scarlet Witch. Wonder Man has died multiple times, but finds his way back to life each time.
So why wouldn't he appear?
No reason! Simon Williams is actually an actor in the comics, so it'd be fun to see an actor play an actor with super powers. Also he'd fit into the MCU in a love triangle with Scarlet Witch and Captain Marvel, and as another member of the team on Thor & Hulks strength level.
I believe Marvel is saving this character for Phase 4. What will Marvel do after The Avengers Infinity War Part II? Possibly a Mighty Avengers movie? He'd be perfect to establish come Phase 4 and becoming a part of that team, consisting of Captain Marvel, Scarlet Witch, and more.
2.) Robert Reynolds A.K.A. The Sentry
Formerly a member of the Mighty Avengers, Dark Avengers, and New Avengers. The Sentry has been around since Sentry Volume 1 Issue 1, from September 2000.
Powers & Abilities:
Chemically Enhanced Physiology: The Sentry's superhuman powers and abilities derive from the Super Soldier Serum as the serum was increased thousands of times and altered making it much more potent. The experimental serum creates a phase-shift in his molecules, causing the Sentry to become partially out of synch with normal reality. The serum induces a photosynthetic reaction, resulting in a hyperstate of consciousness. Though most of his powers and their limits are still unknown, the Sentry has been said to have the power of a million exploding suns
Superhuman Strength: The Sentry's strength varies greatly and depends on his mental stability. The Sentry possesses vast superhuman strength, granting him the ability to lift (press) far in excess of 100 tons easily. He is one of the strongest beings in the Universe. He has demonstrated several astonishing feats of strength during his career, including easily lifting tremendous weights, ripping Carnage in two, taking Terrax the Tamer's cosmic axe and shattering it with his bare hands, lifting a cruise liner effortlessly, and his unrestrained power overloaded the Absorbing Man. The Void was even able to break the Hulk's limbs with relative ease, and the Sentry himself was able to easily kill Ares, the God of War, by ripping him in half. He can also absorb solar radiation for additional strength. The Sentry has yet to demonstrate an upper-limit to his strength.
Superhuman Speed: The Sentry possesses the ability to think, move, and react at superhuman speeds. He has been observed catching bullets and has also been seen moving far in excess of supersonic speeds; his speed on earth is enough to be gauged as fast enough to move at orbital velocity (5 miles a second).
Superhuman Senses: The Sentry possesses vastly enhanced senses. He is able to hear almost any sound at any volume or pitch. The only Earth creature who can detect sounds at the frequencies he can is a blue whale (0.01-200,000 Hz). He has shown enough control to block out ambient sounds to focus on a specific source/frequency (He has demonstrated hearing a butterfly's heartbeat in Africa). The range of his eyesight is also far greater than that of a human being. He is able to detect a single person from hundreds of miles in the air and above cloud level.
Flight: The Sentry possesses the ability to float by defying gravity, utilizing his superhuman speed to fly far above hypersonic speeds (above mach 10). He has demonstrated traveling to the Sun and back in a matter of moments which would require him to fly at speeds faster than light
Energy Blasts: The Sentry can generate light, heat, force, and other forms of energy as powerful blasts and explosions of a yellow color. These blasts are usually generated from the hands and eyes. The maximum power of these blasts is unknown. It has shown previously to be capable of burning Hulks skin and levelling city blocks in the past.
Resurrection: The Sentry appears to be able to bring the dead back to life under extreme emotional distress. After Ultron murdered his wife, Sentry was able to resurrect her by simply touching her. It does not appear he has control over this power, as he was shocked by his ability to do such an act. This may also extend to simply healing others' injuries.
There isn't much he cant do...
The Sentry was once known as the worlds greatest hero, until it was revealed that the worlds greatest villain and Sentry's greatest foe, The Void, was in fact Sentry's alternate personality. Robert Reynolds has multiple personality disorder and was completely unaware of himself being both the Sentry and The Void.
Once he made this discovery, he determined it'd be best and safest for the entire world to be made to forget about both Sentry and The Void. He used physic powers emitted by his clock tower in Manhattan to make the world forget him, himself included. The world forgot about the Sentry and The Void, and he became just Robert Reynolds for a time.
Years later, Robert's memories returned and, along with them, the Void, who rampaged across Europe, murdering many people and heroes alike. The Sentry contacted his former colleagues, but the only one who recalled their shared history was the Hulk. As the Void returned to Manhattan, the pieces began to fall in place and the Sentry's former friends assembled to defend him and the city. Remembering the dual nature of Robert's powers, Sentry and Reed Richards reactivated the Watchtower, dispelling the Void and making the world forget the Sentry once again.
So why wouldn't he appear?
The Sentry would be a tough character to throw into the MCU. He is so overpowered, it would be hard to have anyone oppose him. If kept at his actual power level, Sentry might be able to work as a single solo film, featuring short cameos by other characters in the MCU. If Marvel ever decides to use The Sentry, they'd have to ground his powers immensely for the big screen, which could be done.
I think it'd be best if Marvel gave him a solo flick in the beginning of Phase 4, then keeping him around to later join my theorized Mighty Avengers Phase 4 film. Robert Reynolds is a complicated character, who would certainly need a full film to tell his story. As we know from Marvels announcements, theres simply no room for him on their schedule until 2020 or beyond.
3.) Jennifer Walters A.K.A. She-Hulk
She-Hulk has been a member of the Mighty Avengers, Fantastic Four, Avengers, the Defenders, and the Heroes for Hire. Jennifer Walters is cousin to Bruce Banner AKA The Hulk, and has been around since Savage She-Hulk Volume 1 Issue 1, from February 1980.
Powers & Abilities:
Physical Transformation: As a result of a blood transfusion from her cousin Bruce Banner, AKA the Hulk, Jennifer Walters is able to alter her physical form into a female version of the Hulk. As She-Hulk, Walters' skin, hair, and eyes all turn green. Her frame also gains another 9 inches in height and 560 lbs of muscle and bone tissue. Unlike her cousin, the Hulk, much of Jennifer's gained muscle and bone mass is condensed and several times as dense as that of a human. As a result, though she is noticeably much larger than she is in her normal form, she looks much lighter than she actually is. Also unlike the Hulk, or rather certain Hulk incarnations, Jennifer retains her full intelligence and personality in her She-Hulk form. Most of the time, Walters is able to control her transformation, enabling her to change back and forth at will.
Superhuman Strength: As She-Hulk, she is proportionally stronger than her Jennifer Walters form. This means that any extra strength gains as Jennifer Walters through intense physical training will be amplified, making her She-Hulk form that much stronger. It has been stated and shown that like her cousin, her strength increases with her emotions, such as fear and rage. She-Hulk's strength has extended into her highly developed leg muscles, enabling her to leap great distances or heights.
Superhuman Speed & Stamina: Due, at least partially, to the great muscular strength and development of her leg muscles, she is capable of running and moving at speeds that are beyond the natural physical limits of the finest human athlete. She-Hulk's highly advanced musculature produces considerably less fatigue toxins during physical activity than the musculature of an ordinary human. She can exert herself at peak capacity for about 48 hours before fatigue begins to impair her performance.
Superhuman Durability: She-Hulk's body is highly resistant to all forms of conventional injury. Her skin is capable of withstanding tremendous pressures and temperatures, falls from great heights, field-artillery canon shells, and powerful energy blasts without sustaining any injury.
Expert Combatant: The She-Hulk is a formidable hand-to-hand combatant, having been trained by Captain America and Gamora. Even in her Jennifer Walters form, she possesses sufficient skill in the martial arts to dispatch several would-be muggers much larger than she is. She is also highly trained in the use of weapons and battle tactics and strategies.
Expert Attorney: Extremely intelligent, the She-Hulk is a skilled and experienced lawyer. She has won many cases proving various civilians, costumed heroes, and even villains innocent.
So why wouldn't she appear?
Jennifer Walters is a fun, exciting, and powerful character in the Marvel Universe. Being Bruce Banners cousin, it would be fairly easy to tie her into the MCU. Also, Marvels Daredevil Netflix series is coming, and Matt Murdock is a big NYC lawyer as well, so it'd seem likely they'd cross paths right? Im going to say yes and no. While theres a chance she might pop up at some point as Jennifer Walters, skilled lawyer, I highly doubt she would make an appearance as She-Hulk.
I could actually see Marvel having her pop up as a rival lawyer against Matt Murdock during his Netflix series. She at this time would NOT have her powers. During Phase 4, assuming theres a Hulk solo film again or even another team up film, Jennifer returns and gets mortally wounded. Bruce Banner would then reveal that they are cousins, and they get Bruce to give Jen a blood transfusion to save her life. This grants Jennifer her powers and she turns into She-Hulk.
I just don't see where they would work Jennifer Walters in. The future of the MCUs films are so cosmic and among the stars, and She-Hulk is such a grounded character. She would work as a cameo-making character on Agents of S.H.I.E.L.D. as well, but only as Jennifer Walters. She-Hulk is a truly larger than life hero, and won't truly reach her potential as a character until she's on the big screen, and not on Netflix or TV.
There you have it! 3 major characters who I would love to be in the MCU and see on the big screen, but likely won't see until Phase 4 or after 2020. I cant wait to see what Marvel has planned down the road, especially with future additions to our already massive roster of heroes!
PS: I'd love to see all three of these characters work their way into the MCU and form the Mighty Avengers, a secondary and newer team of Avengers.
