@Bambu Well, I don't want to assume anything, and the OP didn't say where it was. In this case it
could potentially change the outcome. But yes, mostly a joke.
That said, a couple small points: Samus is able to freeze stars, and freeze them long enough for them to be mined for resources like planets are. While she doesn't use the Ice Beam in 2, I don't know if it's specifically excluded from this version of her, canonically or in this battle. If it isn't, though, I don't think duration of freeze effect would be a big problem.
Ultimately, to me, I think the battle comes down to this: Samus wins pretty handily if Kaliber doesn't bring the Lich back infinitely, or if her killing the Lich every time he revives ad nauseum counts as a win, something I fully believe she's capable of doing. However, unless the latter "win" condition is accepted, as long as Kaliber brings the Lich back 100% of the time, I'm not sure Samus can put him down for good, save for the Sonic Boom, and that's only a "maybe" depending on the accepted definition of "breaking reality" in its area of effect, and whether it could overcome/bypass this kind of outside interference.
EDIT: @
Theglassman12 Isn't this whole discussion supposed to answer the question? I guess if I had to answer, it's not really a "stomp" either way, in the traditional sense, because neither opponent is just outright more powerful than the other. It comes down to hax. The Lich has an outside presence who brings him back pretty much forever unless specific conditions are met or bypassed, while Samus has some interesting BFR/bypass hax that might also work. Right now, it seems like the Lich has the edge. But, at least in my view, one hax that wins via endurance isn't exactly "onesided as hell." Then again, I'm new to debating, so maybe some win conditions are.
