Godlike
Belial (Wild ARMs 4) vs Ghaleon (Lunar: Silver Star): Even if everything goes her way (surviving one round from Ghaleon, high disrespect for Ghaleon's speed), she gets what... 7, maybe 8 attacks off? And I still don't think that's enough.
Heavy
Sharon (Legaia 2: Duel Saga) vs Bishop Stone (Xenogears): Sharon wants to fill her AP with her opening attack then have a MA to win with. This... works even assuming she can't use a MA at exactly 50% HP (and to be fair, due to how rounding works in most games, this is probably the case). Unless Stone can slow her and then double at the right time, but that requires not letting people wait and even then may not work, I'll leave that to others.
Middle
Melbu Frahma (Legend of Dragoon) vs Warlock (Suikoden IV): Warlock has no status protection besides whatever credit I'd give his MDef, and you don't want to try to blitz Melbu with magic (I know Warlock is partially ITD, but still).
Data mine
Fire Emblem Fates: Played it, all routes, it's great, people should play it, etc.
Bravely Second: End Layer: Played it (not done yet, but getting there, and will certainly be finished by the time it can even be considered for ranking.
H/G pool:
Chris, Black Fiend, Magus, Sharon, Bishop Stone
Black Fiend really hates Silent Lake, although she's a hell of a wall so... mm. Actually, she has a counter to it, she can use her really fast MP-drain attack, which should limit Chris to two SLs at most, and since she's over 10 pdur even some crit-ITD hype isn't going to let Chris put much of a dent in that, and then when SL is gone Blackie 2HKOs. Against Magus she has NE magic damage, lol. Against Sharon, MP-drain again. That leaves Stone who is a major spoiler with that MDef, while Blackie's own spoiling doesn't affect Stone at all.
So is Stone godlike? That'd be super-weird. A loss to Sharon is described above, Chris is the type of healer he hates (slow helps a bit, but the healing removing it means not much). Him vs. Magus is certainly close... Stone 11HKOs, Magus 12HKOs with his physical. I think Magus is barely faster (Slow doesn't work), and very fortunately for Magus I let him choose his counter, so the tickles of Dark Bomb slowly add up and let him just win the slugfest.
Chris can turtle through Magus nonsense pretty well. She can drop SLs and unload free damage (Magus can't outslug her during that time), or just get through by healing periodically since Magus damage isn't too hot. Can't imagine she loses. Against Sharon... I dunno. She has a hard time avoiding a MA, and charm could mess her up too. She could win (2HKO with Phoenix as a finisher), but needs everything to fall her way. I'm open to argument on this one but it doesn't really matter.
So actually Sharon's looking damn good, go figure. Magus can't dodge MAs worth shit and is just OHKOed by one I think, for all that even if he doesn't he'd need a finishing physical to do the job or Sharon pokes his normal defence for the win. Sharon in Godlike? There are weirder things I guess.
Black Fiend 3-1
Sharon 3-1
Chris 2-2
Magus 1-3
Bishop Stone 1-3
Conclusion: Stone stays down. Sharon up... Magus down? Feels weird.
M/H pool:
Tiamat, Auron, Edgar, Justin, Melbu Frahma, Warlock
So let's start with Melbu I guess. The durability is too much for Tiamat... though it might not be if not for the NE magic damage in form 2. Auron might be able to take this if not for confuse at the end, I think (he can block petrify). Edgar is bad against bosses, Justin might take this if not for SP limits, Warlock is discussed above.
Auron has ITD which Tiamat already hates, Magic Break makes her even more unhappy if that's seen as working. Even if it doesn't uh one low-HP shot from Auron may well kill. He gets confuse-locked by Edgar (or IDed if he blocks that), ID protection + Power Break + counter beats Justin, he can't hit Warlock first turn then gets one-shotted by Earthquake (or close enough that it makes no difference).
I certainly don't view Edgar's status as good enough to overcome Tiamat's resistance, but he 2HKOs with CHAIN SAW. (Yes.) His status cheese also beats Warlock, but not Justin who blocks both relevant ones.
Justin does 55.7% against Warlock's 55.8% pdur, are you kidding? Saves me the trouble of deciding how I view evade there. Against Tiamat he hits the wrong defence while Tiamat 3HKOs... even if she 4HKOs it doesn't matter.
That leaves Warlock vs. Tiamat, and Tiamat immuning earth is a bad time for him, as is her barely 2HKOing his bad HP.
Melbu 5-0
Edgar 3-2 (loss: Justin, Melbu)
Auron 2-3 (loss: Edgar, Melbu, Warlock)
Warlock 2-3 (loss: Edgar, Melbu, Tiamat)
Tiamat 2-3 (loss: Edgar, Melbu, Auron)
Justin 1-4 (loss: all but Edgar)
No tiebreak for the middle cluster, although I'd strongly caution against downgrading Auron! Inclined to say Melbu up, Justin down (although really none of the Heavies should downgrade... I can see Tiamat but as this pool shows she tends to spoil too much).
L/M pool:
Pent, Bob, Nelis, White Wizard, Tia
Let's start with Nelis since she's very much on the wrong division border. Pent gets 2HKOed and can't counter, RIP. Bob's tougher, since his transformation boosts his MDur to the point where Nelis needs three turns to kill him... and Bob is faster, so yeah never mind, he 2HKOs first. White Wizard resists fire which is also a problem for Nelis. Nelis does 31% with her best spell or 27% with physicals. WW can alternate Invis 2 and Cure 4 and get to immunity to all but the fire spells before she is killed, at which point I think the lower healing outlasts Nelis' MP too (all but the best 7 spells do 10%) but it's kinda close. Nelis OHKOs Tia.
Okay so let's look at Bob. He 2HKOs Pent so Pent gets 2 turns + 1 counter and that certainly isn't enough. But Bob might miss once, his Tech is slightly subpar and Pent can dodge some. So Pent gets 3 turns + 2 counters? And that's still not enough! Luckilly for Bob he has 3 transformed turns. WW's healing is bad for him, though, especially since she gets to buff once first. At worst she heals off his three turns, unless he doubles which meh not inclined to hype especially since he'll likely miss once anyway. And then he only 3HKOs so can start throwing in Invis again and eke out a win. Finally, against Tia he... misses the average damage KO by 0.1%! Second time in a week, wow. 61.1% against Tia's 61.2% pdur. Well that means he's hosed.
So WW's 2-0 already, crazy. Against Pent... Pent gets the drop on her with Thunder which 3HKOs, but then WW uses Wall and it's a 9HKO. But... good lord, WW offence. Every hit triggers a counter and Pent and it's a 19HKO to average, which Pent is above in practice (his evade should more than offset his PDur). She does have one shot of Holy in there, though, which is a 5HKO and shaves off a bunch of her needed turns, probably gets it down to 20 or turns of offence. She can attack three times then heal to full so that's 15 attacks or so (less actually, since Pent's opening hit) then she has to use weaker healing. And that only somewhat outpaces Pent's damage, she can use two shots of Cure 3 to get in one more attack, three times. So three more attacks. Plus one at the end. That's... 18-19? Mm. Close but I think she comes up short, especially since we haven't hyped the effect of Pent's modest crit forcing her to heal a bit more in a long fight. I'm reminded what L'Arachel won this.
All that for one match? Okay. WW vs. Tia, then. Tia's healing gives her the edge here, her resources last longer and she'll get IPs. I mean Miracle is probably GG since surely WW can't dodge that ever.
What a ridiculous field. This leaves Pent vs. Tia. Pent 2HKOs with Elfire. Or even Elfire + Thunder. That said he has to attack or Tia rains sleep on him which does occasionally hit and stick and gives her a free hit. So Tia heals a bunch and she gains IP. On a doubleturn she uses Battle Lust, then can OHKO with Aqua Attack. This needs 78 IP, with Pent doing constantly around 50% damage... 3-4 attacks will be enough. So yeah, Tia kills quickly enough that crits don't enter the equation.
Tia 3-1 (loss: Nelis)
White Wizard 2-2 (loss: Pent, Tia)
Bob 2-2 (loss: Tia, White Wizard)
Nelis 2-2 (loss: Bob, White Wizard)
Pent (loss: all but White Wizard)
Weird field, we were very close to everyone 2-2! Pent down I guess.
