Given the option of forming my own Suicide Squad, i would choose different characters from different universes and dimensions. Many great characters to choose from. But I've managed to bring it down to the below. Enjoy. :)
CARRIE - Stephen King
Psychokinesis, that's all i would say. One destructive force to be reckoned with. Imagine The Joker laughing at her. One of the best characters developed by Stephen King, her frightening telekinetic abilities and lust for revenge would give Arkham Asylum a blood bath.
SNAKE PLISSKEN - Escape from New York
Need to assassinate, extract or escape? Snake is your man. A highly effective combatant and a gun wielding muscle man, Snake will do anything to survive.
A former Spec Ops and War Hero, sometimes he does have a code and might do the right thing.
Snake: "You'd better hope I don't make it back!"
V - V for Vendetta
Having no identity or background makes V a highly dangerous character. A Genius with enhanced strength, reflexes and expertise in swordsmanship and marksmanship. He is an anarchist and uses stealth and demolitions as his primary weapon. But face to face he is even more dangerous.
DARYL DIXON - The Walking Dead
An expert tracker and efficient Zombie killer and hunter. One of the most loved characters on TV, he'd make a great addition to the Suicide Squad. Highly volatile and aggressive, his accuracy with the crossbow makes him a very skilled hunter.
LOLA - The Transporter 2
Remember the gun wielding, crazy chick from Transporter 2. Wouldn't she be just perfect for the Suicide Squad, she might even give Harley Quinn a run or may be not. She shoots, she kills, she licks (ask Frank Martin). She is the whole package.
DARTH MAUL - Star Wars Episode I - The Phantom Menace
The first apprentice of Darth Sidious, Darth Maul wields a double bladed light saber. He fights with a high ferocity, blinding speed and impressive agility. He survived after being cut into two by Obi-Wan but came back even more terrifying.
Well it's pretty simple when you come to think about it.
All of them are expendable and can be sent for any missions.
Carrie: She's strong and powerful. Reminds me of Jean Grey at times. Make her your pal and she just might obliterate anyone for you. Amanda Waller might use her emotional state and prep her to join the squad, he'll even The Joker mite use her to get his tricky jobs done.
Snake Plissner: An excellent extractor and combatant. Throw him anywhere to get your job done, he will survive and finish the job.
V: A tactician and strategist with all his more than human qualities, make him the strongest member. He can lead the squad. Snake might have a difficult time with V, but who wants a perfect team. Internal conflicts is what makes them more interesting.
Daryl Dixon: He is a drifter, a lone wolf. Just the type of guy Waller might wanna recruit. Excellent marksman and a survival specialist. He might relate to Snake more, but might side V when the time comes.
Lola: She is the bad ass of the squad. Literally, send her just for chaos and destruction. Joker and Lola romance in the making.
Darth Maul: Double-blade Light Saber with mastery in the dark side of the Force and a violent fighting style. Who wouldn't want him?
I know it was supposed to be a 4 Member squad but couldn't cut them off.
If i had to choose from this list, the final four would be Carrie, Snake, V and Lola.
Honorable Mentions: Scorpion (Mortal Kombat), Vegeta (Dragon Ball Z), Nina Williams (Tekken), Mello (Death Note). They were part of the final 10 characters i had in mind for the Suicide Squad.
That's about it.
Hope you liked my selections for the alternate suicide squad. Post your comments below. Always happy with feedback. Cheers.
