I’d like to see any of the following:
Half man / half demon: Or half woman / half demon. Basically, a character that has certain powers as a human and then alters his/her form in instinct and gains some cooler versions of those powers.
I’d like to see them as someone that’s been brought in to our world by Gargos, but you find out that they’re a less than willing servant, as they’re just trying to regain their humanity. Perhaps forms a kinship with Sabrewulf over this.
Old Sage: I love this archetype, and I’d be curious to see where IG could take it. Someone looks frail and feeble, but is actually quick, elusive and agile. Perhaps someone that could be in Jago’s storyline?
Perhaps the use of a walking stick and some sort of mystical powers that they harness. The type of character that can turn an opponents moves against them would be cool. I’d love to say drunken kung fu, but almost feel that’s been too overdone. If there were a way to incorporate some of that sort of deceptive power and style without needing the drunken trope, I’d be all for it.
MMA Fighter: I shadowy rival for TJ Combo. A counter/grappler character who could actually do breakable throw combos as autos using strikes, jointlocks, etc. Not sure if this could actually be done, but if this could be pulled off well in KI, I think it could look awesome.
Maybe TJ defeated this guy back in his metal arms days and crippled him, but he fought his way back to seek vengeance even though TJ’s a good guy now, so he’s working for Ultratech and perhaps has some cybernetics of his own, like a robotic arm perhaps.
Vampire: Others have said this, and I tend to agree. KI could use a vampire. Someone that’s a bit of a cross between Gary Oldman’s Dracula and Symphony of the Night’s Alucard. A style and flair, with a slight lean toward steam punk, but someone that could somewhat appear as though they could pass in modern times. An eclectic mix that makes it feel like IG’s unique take on the character.
They’d have to have a blood suck type of move that regenerates health, maybe in their throw. Perhaps a “thrall” type of move to control or confuse the opponent briefly." Maybe even the use of a minion or two that appear on screen for special moves. A mist type of counter move would be cool, as well as the ability to morph in to bats for their dash and perhaps a special moves as well.
Kunoichi: A female ninja. Use of throwing a throwing star projectile or perhaps explosive kunai. A teleport move where she disappears in a smoke cloud and falls from the sky in various places depending on LP, MP or FP would be cool. Perhaps a sort of grappling hook type gadget for her throw and a special move, and two jutes or small swords that she spins in her hands during combos ala Omega Red in X-Men Children of the Atom.
Perhaps a rival for Kim Wu and/or Sadira. She could come from her own clan with a specific purpose; a loner type perhaps. Face concealed, except for her eyes. The top of her head concealed except for a long braid that tumbles down her back between the folds of her head-gear/mask.
FYI, sorry, I wish I could post pics for these ideas, but can’t do that at work.
