I do try, lol. I realize Samus does have that evidence of a personality, and working to keep to that evidence is a challenge I enjoy taking on. It's not for everyone, I know, but I enjoy that bit of challenge to keep to what's canon. With Samus I scrapped Other M's shitty Samus persona and went with what all the other games presented, and built off of that to try and get a fully fleshed personality.
For my needs to roleplay something mostly original, Kalama's got that down pat for when he starts getting more involved in interactions. He's never, of course, doing combat, but he'll be participating in dialog and such, providing some pointers here and there in ways he currently can't since he's not able to actually send people around the internet. He can do it just fine everywhere else, but right now he's just going "heads up, this is next" while the crucible yanks you into a world, if that makes sense. Feel free to question this stuff so I (well, we) can get it all settled in an agreeable manner.
EDIT: Kaze, first things first, I'd like you to actually fill out the personality section here. Everyone else did, it just makes you look kinda lazy by comparison and it would be unfair if it got accepted that way when everyone else put at least a bit of work into that section. Doesn't have to be anything fancy as long as it's something for you to build off of.
