Godlike:
Ghaleon (LSSSC - PC form only) vs. Galuf (FF5 - Assume Earth Crystal Jobs): I remember Ghaleon having some mid 3 digit damage when 2 Vigored Sword Danced Alex could barely break that. He also was still level 99 vs. midlevel PCs with a Wind Cane (admittedly, horribly stats); Galuf is kind of screwed.
Lina Inverse (Slayers RPG) vs. Goku (DBZ:LotSS): Lina isn't a Godlike, *NOR* is she a temp. She joins in the last stretch of the game permanently (which is about as long, relative to the game's length, as TotA's post Absorption Gate Arc.) Being level 99 doesn't mean much when you have 4 other level 99 PCs. Anyway, Goku is a Godlike based on his absolutely obscene damage and durability. Lina's a fun Heavy (Lots of variety, good stats all around, etc.), but Godlike she is not.
For the record, Goku is technically not a Temp too! Granted, he only joins for the last two fights, where as Lina's there for the entire postZelas Arc, so yeah.
Anyway, for better plot analysis...Goku has 4,999,999 BP to an average of something like 1.3 Million (I don't know the exact value; just Piccolo is above average (1.9 Million) and Vegita is below (1.1 Million), in a game where this counts for Damage, Durability *AND* Evasion. Lina can't really do squat to him before Goku gets his first turn, and Goku has a pretty clean overkill. Yeah, yeah, OMG GOKU IS STUPID POWERFUL!! sounds like idiotic DBZ Fanboyism...but based on LotSS? Its kind of hard to argue this. At worst, he's a variation of VP1 Lenneth with the GR.
Heavy:
Dark Knight Cecil (FF4) vs. Lezard Valeth (VP2 - PC form only): Not allowing Meth Seals today, so yeah.
Odessa Silverburg (S1) vs. Nicholai (SH2 - PC form only): Nicholai's stats were slightly above Karin's, which is by no means bad, of course...but Odessa's were similar to Tir's whose stats are...somewhat better, and Wind Rune to match.
Middle:
Shinjiro Aragaki (P3) vs. Canaan (XS3): Can't vote.
Milda (G1) vs. Asch (TotA - stick with his first temp appearance for this, i.e., the less laughable one >_>): Milda's damage was absolutely obscene at the time, from what I recall, and her HP was good too. Asch was...Luke with magic, which isn't really a bad thing mind! Maybe a few more skills putting him ahead of Luke on damage at the time to boot, but still, nowhere near the same level as Milda.
Light:
Ted (S1 form only) vs. Alma (FFT - LESALIA FORM ONLY): When in doubt, hype MBarrier > PC who didn't really stand out in anyway with no skillset <_<?
Luis Virgil (XS1 - PC form only) vs. Samson (AtL4): This fight fails.
