I mean truthfully, the argument of "hey megalo = power -> power = chara -> CHARA THEME" is pretty weak if you compare it to others.

If it is Chara's theme, why doesn't it play during all Genocide boss fights? Why does it not play on Undyne the Undying and Mettaton NEO?

Songs are not purely theme songs of a character, they're themes of an interaction between characters with a given mood.
