Well dont know how much help i can be since i dont like to play villians... i would think that with the seven deadly sins and ur pick of envy i would go with the mastermind. Because i dont really think someone who is super strong in a suit of armor would be envious of someone else in some cases. Greed would of been cool but pride would also rock as a toon. Ok well goodluck in whatever u decide to make.
I was starting to lean towards Mastermind, thanks for the input. And you do have a point there.
I was going to try and make Greed as a Thugs/Pain Domination Mastermind, saying he was also without super powers but was street-smart, and had a posse that ran around with him stealing things and doing other malicious acts of greed.
But I think that might actually be enough to convince me, so I'll try and go make him now 
Thanks for the input!
think of how envy feels. I must have that, why cant it be mine, if I cant have I will smash it!!!!
I'm planning on making a villain to pair with my friend's Stalker. I always wanted to make characters based on the 7 Deadly Sins, and since Greed's taken, I'm going to try Envy (or at least variations of the word until something fits).
What his backstory's going to be is pretty simple. He's going to be one of the 7 Deadly Siblings, one born without any powers. He was also born horribly disfigured or something of the sort, so he had a difficult life. Being the embodiment of Envy, he envies everyone for their natural looks and the super beings for the powers they were gifted with (he feels he should have gotten them as well).
In actuality he does have a super power - super intelligence. Though he's not aware of it being a power, since he spent his dark, isolated life learning and reading and such. Anywho, he uses his genius to either turn himself into a cyborg, or construct a robotic suit. This is where the trouble comes in:
I can't decide which powersets/Archetypes to use. The two ATs I'm ruling out are Stalker and Dominator, Stalker already being taken by my friend and Dominator not having powers I'd like to use.
Brute - He could either have Energy Melee/Energy Aura (his suit/cyborg body is like a power generator or something), Super Strength/Invulnerability, or a combination of them.
Mastermind - If he's smart enough to make himself into a cyborg or make a powersuit, he should be able to make himself some robots, right? He could maybe have a chip in his brain that he uses to communicate to them, to give them commands instantly while he uses traps and devices he constructed himself.
Corruptor - Either Assault Rifle/Traps or Energy Assault/Traps. I'm sure y'all understand why.
I just can't decide, so I came to the creative minds of you all to aid me in this dilemma. I know the story isn't completely plausible, but it's good enough for me. I just need opinions from you guys on what's best, both theme-wise and team-wise. I'd like to choose one that would compliment a Stalker, if at all possible with these choices.
