Considering how many characters there are in Marvel, Gaming, DC and other fandoms, narrowing the list down to just four was a difficult task. Every character has their advantages and weaknesses to add to the team. However, after days of going through every combination and every outcome, I'm confident I've chosen the best team for the job.
Team Leader: Ant-Man (Scott Lang)
With his unique ability to shrink and re-size at will and his cynical sense of humour, Ant-Man can be used as the team's secret weapon and will always keep the morale of the group high. Being able to fit through any gap possible and keep his ordinary human strength would be a great advantage for the team. Not to mention his sarcastic jokes and general personality that is bound to keep the atmosphere positive. Furthermore, his control of ants in close proximity would allow him to traverse large amounts of ground at high speed and is a great way of breaking through enemy territory without being seen. Plus, no one would want to go up against a swarm of man-eating ants.
1st Draft: Reverse Flash/Professor Zoom (Eobard Thawne)
Now we all know that "The Flash" is supposed to be the fastest man alive, but there is one person who is faster: Reverse Flash. This is someone Barry Allen has never been able to keep up with, so therefore, no one can keep up. With the ability to run at incredible speeds, he can easily outrun anyone. Furthermore, the speeds he runs at allow him to replicate himself in multiple places, so he can also easily outnumber the enemy as well as run at breakneck speeds. He is certainly a vital asset to the team that could change the tide of any battle.
2nd Draft: Mario
Known for his sporting prowess, expert karting ability and all round excellence, Mario is certain to boost the strength of any team no matter the situation. He is the perfect all-rounder, which is proven in each of his sporting games, making him the perfect choice. His ability to jump high and his wide range of mushrooms and powerups would be a huge advantage for the team. Furthermore, being equal in attack, speed, and accuracy, he is the perfect player and the perfect ally for any team no matter the situation.
3rd Draft: Darth Maul
As one of the few positive outcomes of The Phantom Menace, it's unfortunate that Darth Maul was only in one of the Star Wars films. Despite this, he is still seen as one of the most powerful Sith Lords to ever exist. With his double-bladed lightsaber and powerful control over the force, he is certainly a force to be reckoned with. Furthermore, his abilities using the force enable him to jump far distances and sense incoming attacks, plus his deflection skills will protect him and his fellow allies in battle. Darth Maul is a necessary companion who will strike fear into the hearts of his enemies.
With these four, any threat facing the Earth will stand no chance. With a fair blend of attack, defense and stealth, this team will be completely prepared for any kind of danger.
