I think I take Maribelle as Valkyrie, for myself. Think this is fairly obvious, moreso than Lissa.
Maribelle (FE13) vs Paula (EB) - Holy crap this is awful. Maribelle wins the tiebreak and gets in a crack with Thoron, though, so Paula just -never- gets to land a crack at her, since she's constantly getting PSI Shield broken.
Maribelle vs Slime (SaGa) - Bolganone 2HKOs Slime and Maribelle's mdef makes HP Drain -suck- even for healing, so this is pretty clear. If she doubles (which... isn't entirely unreasonable, Slime rams into the TB speed floors pretty hard), this becomes simply -ugly-.
Maribelle vs Mogu (BoF1) - Maribelle goes first and 3HKOs with Rexcalibur (Mogu can resist both Fire and Lightning). Since Mogu doesn't even 2HKO Twinkles (...) and doesn't double either, this is a slaughter (as Snowfire noted, he loses this match even if you -do- see him 2HKOing).
Maribelle vs Shiho (VP1) - Counters ensure she works this out.
Maribelle vs Mustadio Bunanza (FFT) - Mustadio two-rounds (doubles and 4HKOs), so Maribelle -really- needs to 3HKO back. Nooooooooot happening.
Maribelle vs Leon S. Geeste (SO2) - yyyyyeah, Maribelle 4HKOs and can circumvent Leon's elem resists. Meanwhile, he can't realistically get past her Res.
Maribelle vs Mullen (G1) - 2HKOs and doesn't get OHKOed back.
Maribelle vs Alenia (S5) - Maribelle might not 2HKO, but Alenia -definitely- doesn't 2HKO back either.
Maribelle vs Healie (DQ4) - Oh dear god. Healie even doubles, but does it even matter with -that- damage?
Maribelle vs Rufus Shinra (FF7) - Maribelle 3HKOs and Rufus likely only 5HKOs back. That doesn't work.
Maribelle vs Mukumuku (S2) - Should double and 2HKO. Maribelle might 2HKO back, but don't think it's too likely.
Maribelle vs Thief (FF5) - Thief 5HKOs and triggers counters. That ain't working even when he's doubling, he gets 3HKOed back.
10-2. Yeah, Maribelle's not really Puny. Ranged counters and not being doubled by average as a Valkyrie actually -do- go a long way to keep her viable above the lowest threshold, as does her notable magic durability.
Gong (Shining Force) vs Paula (EB) - Gong manages the amazing feat of 4HKOing Paula with physicals, but it doesn't really matter: the healing means he outlasts her anyway. Freeze kicking once in could suck, but Paula uh 5HKOs him back, so he can afford to just heal once he hits 50% HP.
Gong vs Slime (SaGa) - If you can heal -once- against Slime, you don't lose.
Gong vs Mogu (BoF1) - Oh good lord.
Gong vs Shiho (VP1) - I'm PRETTY sure Shiho's odds of winning here are better than the odds of Gong landing -two- doubled crits in a row at a point where she's recharging. Otherwise, you need to at least 4HKO Shiho to win, and Gong's very bad at managing this (Renault could make do due to counters and ACTUALLY BETTER DAMAGE, Gong uh).
Gong vs Mustadio Bunanza (FFT) - Yeah, don't think Arm Aim really tips this, Mustadio and Gong roughly 6HKO each other and Gong's full healing is a bigger threat than a perfectly timed Arm Aim proc.
Gong vs Leon S. Geeste (SO2) - Um yeah, 3% mHP regen ain't tipping this, girl.
Gong vs Mullen (G1) - Gong goes first and 3HKOs. He so doesn't need to heal.
Gong vs Alenia (S5) - Gong 3HKOs at worst and is faster. Alenia doesn't 2HKO.
Gong vs Healie (DQ4) - Uh I'm not so sure. Healie is faster and has more shots of healing, but sports 2/3 the durability, a fraction of the damage (a fraction of Gong's MIGHTY 7HKO. Amazing) and Gong can just use Heal 3 for 50% healing, which he gets a third shot of. I actually think Healie loses this out, especially considering the minor spikiness in ShF physical damage.
Gong vs Rufus Shinra (FF7) - 10HKO damage and half-PC HP against someone with healing.
Gong vs Mukumuku (S2) - That one shot of full healing.
Gong vs Thief (FF5) - See above.
11-1. Yeah, that ain't a Puny. The limited healing means he usually can deal even with 4HKOers as long as the stat split isn't too notable otherwise, and he's close enough to average in general stat spreads to make this viable in Light. Of course, he doesn't really deal with healers who have anything resembling resource depth (that loss to SHIHO is pretty telling, and he'd eat it to Nara as well due to 4HKOing her ass), but them's the breaks.
Edward Chris von Muir (FF4o) vs Paula (EB) - Between the weird coding that possibly makes EB PCs immune to Brainshock at endgame and the fact I think I'd give Paula the average speed the tiebreak (mostly because her being average speed is an endgame thing, she's game-best speed until Poo lands the Cloak of Kings), um yeah. She 2HKOs (!!!) and gets 4HKOed back. If you're 4HKOing Paula, you DESERVE to lose.
Edward Chris von Muir vs Slime (SaGa) - Oh, for crying out LOUD.
Edward Chris von Muir vs Mogu (BoF1) - Not so sure he 2HKOs, but also not so sure I respect Ed's Confuse that much.
Edward Chris von Muir vs Shiho (VP1) - Sigh. Confuse actually works against damage this wretched.
Edward Chris von Muir vs Mustadio Bunanza (FFT) - Faster, statusblockers. The end.
Edward Chris von Muir vs Leon S. Geeste (SO2) - Leon should be able to -at least- 3HKO Ed and the regen of all things is horrifying for the bard. No dice.
Edward Chris von Muir vs Mullen (G1) - Um yeah, Mullen 2HKOs and Edward -3HKOs- back. When you're -3HKOing- Mullen, you really have it coming.
Edward Chris von Muir vs Alenia (S5) - I pulled my HP estimations on Alena up a little bit, so I think she should avoid eating a 2HKO here. This is good, since Edward gets almost OHKOed back.
Edward Chris von Muir vs Healie (DQ4) - Faster!
Edward Chris von Muir vs Rufus Shinra (FF7) - Comparable durability! Rufus is much faster.
Edward Chris von Muir vs Mukumuku (S2) - Damn.
Edward Chris von Muir vs Thief (FF5) - Faster.
2-10. Dear god, he's so bad.
