Godlike:
Althena/Luna (Lunar1) vs. Fei Fong Wong (XG)- I spent like an hour mulling this over. Basic conclusions.
- Both are mortal. Whether Althena was originally mortal or not is debatable, but Luna certainly is. Fei is obvious.
- Fei's power is essentially infinite. His plot power is, basically, "draw as much power as he wants to from the Zohar", which explicitly has no upper range to its output.
- Althena's power, at a given time, is finite. Lunar 2's backstory video suggests strongly that Althena's magic is mostly invested in her world, an in order to deliver a divine level beatdown she has to reclaim it (this happens with Zohar, and note that the Blue Star is not habitable after the fact.) While it seems that her power grows over time as her creation flourishes, at a given time it only matters so much.
- The last two don't matter much. Both are ultimately killable without earth-shattering powerlevels.
- Consequently, the battle comes down to personality. Fei, by game's end, is pretty laid back and would never unleash even a fraction of his power except to save someone. He's just not the type to cut loose in a friendly sporting match.
Luna, meanwhile, seems to handle Althena power very, very badly and be pretty "Back off, Mortal!" while using it. So, here, she seems much more likely to have the killer instinct needed to pull this off.
So, match to Althena/Luna (Lunar 1)
Heavy:
Zack Fair (CCFF7) vs. Lucia (Lunar2)- Eh, she's not immortal, and I wouldn't let her do the Althena Mode thing at a whim (unlike Althena herself). So... eh, Zack isn't inexperienced with this sort of thing.
Middle:
Flik (Suikos) vs. Gordon (Dis1)
Light:
Deneb (OB) vs. Genis Sage (ToS)- No vote.
