Bass

Bass is presented as an extremely smug, bad-tempered, egotistical, rebellious, fiercely independent and arrogant individual who believes that he's the strongest above all else. Bass is very prideful and thinks quite highly of himself, labeling everyone else around him as inferior "junk robots". He has always been shown to hold a rivalry with Mega Man, but aside from him, Bass happens to have hatred for every robot that was created by Dr. Wily with the possible exception of Treble, Reggae, and, needless to say, himself, since he feels that they're standing in the way of his goal to destroy Mega Man and become the strongest. Bass looks down on them, believing himself to be superior to them in every way, shape, and form. However, a notable aspect of his personality he showed was that he seemed to have some degree of respect for humans, since they created robots. Duo says that there is goodness in Bass even going so far as to say that he has "justice energy", which the latter ignored, saying that he only wants to fight, claiming that his only concern is who the strongest happens to be. Despite his rivalry with Mega Man, he is willing to work alongside him if it is to his benefits, and his aiding Mega Man in defeating Rockman Shadow's forces. The latter instance also implied that the aftermath of the battle left Bass with some respect for Mega Man. There's a possibility that Duo's claim of there being goodness in Bass is true, since he was able to use the Evil Energy Capsules without dying. He even began to show some form of concern for King.
