Oh yea is that diamond clad Nucleoid the one leading the attack on Youkai Mountain?
If so Bass will go in and attack and get his ass handed, X will try to fight but get his ass handed, and Zero will come in and some real shit will go down.
Most of my characters haven't really done much things important.
X hasn't really interacted with anyone really except John, Shou, Alia, Axl, Zero, and just a few others for a short period of time. Never really interacted with Renamon whatsoever, and was only in a few fights (though that kind of makes sense as X isn't the one for mindless fighting, only fighting if the lives of innocent people are on the line.) It seems like X hasn't done much. One would think that since X is part of the main gang that he would have a bit bigger roles than he seems to have at the moment. I also noticed that John seemed to help X at times near the start of the RP. Also for some reason I can imagine John becoming sort of like a father figure to X in a sort of way.
Zero has been in more fights which makes sense for him as he is more of a fighter, however he hasn't really done much important things at all. The only ones he really interacted with was Isaac, Nitori, X, Alia, EVE, and Axl. Other than that all that the others really know about Zero is from what X said about him.
Axl has only been in like one battle for a short time, has been more of a talkative character. He already has his only upgrade (his white armor upgrade) but he does not know how to use it.
The one character that seems to have a bigger role in a story is Chris Redfield who is the title character of the London Arc pretty much.
