I was about to make the same nom, Malcom, and certainly approve. There's also GIGA BOWSER hype but since he apparently can't use it on demand according to WGAYP, it only temporarily evens the odds against Chu-Chu before his incompetence strikes. Also Bowser winning is hilarious, so agree he should be in Warriors. That said... does Arek the Absolute actually get any plot in other Lufias? In Lufia 2, we know basically nothing about him...
Re Jo'ou, Fei on the other hand can go straight to Divine Beings since he's got a magical mech literally hyped for god-slaying and Xenogears is legit for hype in a plot power tourney. He easily defeats several of the Divine Beings hyped already, and is potentially even better depending on how much vague chosen one destiny BS you're willing to hype. (On that note, Andy's SH Yuri nom is also arguably qualified for Divine Beings, since he's another Godslayer, fused with Amon which presumably makes him of comparable power to Nicolai / Rasputin both of whom I'd kneejerk to Divine Beings, but that one is definitely more debatable. I'd certainly consider Nicolai / Rasputin / Yuri / Albert Simon of comparable power, and quite possibly better than Lady in a plot power tourney, and Jo'ou nommed Lady for Godlike, but definitely an edge case.)
Also in my noms already, but definitely would assume that Kefka qualifies for Divine Beings, absorbed the power of the Statues, Light of Judgement, requires 12 super-powered people to take down, etc. (WoB Kefka for Superhuman, sure.)
