Knight (Bravely Default) vs Lambda Zellweger (WA4) - Knight needs at least a 3x Shield Charge, ideally a 4x to break through Blue Destiny on average. Considering Lambda -triples him off the bat-, that's 1x PC HP worth of damage before Knight gets to Default even once. That ain't working out even if you allow Default to half damage.
Knight vs Genevieve (VP1) - I don't think Knight mdur is good enough to survive an Indiscriminate string on average. So it goes.
Knight vs Athos (FE7) - Knight does reduce Nos damage a decent deal, but Athos is reasonably durable to physicals (as in he may survive SC x2 even -before- Nosferatu comes into play). So yeah.
Knight vs Yaridovich (SMRPG) - He survives Shield Charge x2 and has enough magical damage to outrace a Default strategy.
Knight vs Indalecio (SO2) - Indalecio... 4HKOs Knight, sure. And Knight needs either Default x3 or Default x2 => Shield Strike before building up to a fatal Shield Charge string - not to mention he risks getting 5-4'd. So it goes.
Knight vs Groudon (PKMN) - Knight can't OHKO off the bat, and Bulk Up + Rest ensure he can't kill Groudon -ever-. Past that, Groudon also sports plenty of magical damage, which finishes covering his bases.
Knight vs Luc (PC form, S3) - Funeral Wind claims another victim.
Knight vs Legretta (TotA) - Jesus christ, Legretta -7HKOs- Knight with Eclair De Larmes at full HP and I don't see her tanking a full 2.32x PC HP Shield Charge x4 string. Default => toodles.
Knight vs Georg Prime (S5) - Physicals vs. Knight.
Knight vs Nash Rumack (Lunar:SSSC) - This depends on whether Mind or MDef are the stat that governs status resistance in BD - my kneejerk is that none of Nash's non-sleep status is turn one against Knight MDef, and he's certainly immuning -that- given the chance. Shield Charge obviously OHKOs, so Nash gets that one shot. EDIT: MDef for now it is.
Knight vs Meliadoul Tingel (FFT) - Welp. Knight doesn't one-round, but it ultimately doesn't matter. Shields are responsible for most of his defense stats and he's still very, VERY tanky without armor and helm. He'll survive long enough to kill Meli even though he'll likely need at least a 4x Shield Charge.
4-7. Knight's complete inability to mount any sort of sustainable offensive pressure reared its ugly head in quite a lot of matches, so did the vulnerability to Godlike-level magic offense. The fact he loses to -full HP Indalecio- is kinda striking in this as well.
Vampire (Bravely Default) vs Lambda Zellweger (WA4) - A Brave-blitz -would- be the thing to break through Lambda's Blue Destiny, but Fireball doesn't OHKO him unless he buffs Attack to 1.5x. (and even that's arguable). Welp.
Vampire vs Genevieve (VP1) - I suspect M. Attack debuffing won't be enough to keep Vampire afloat for the time he needs to get into a comfortable position. It avoids a OHKO at best and it'll also eat into his healing effectiveness something fierce.
Vampire vs Athos (FE7) - Even if I see Athos evade working on Battle Thirst to some degree (I think I do), Vampire can more or less keep a lock on Athos once the first connects. Once that's taken care of, the parasitic buffing game comes into play. Vampire still has -some- trouble even then, since he's stuck with his MT damage to avoid counters and Nos/Luna will be an annoyance if Athos gets a turn in the in-between... but feels like Vampire has a sufficient degree of control here, especially with physical status in play.
Vampire vs Yaridovich (SMRPG) - Once again, it's the question of whether Vampire can survive long enough to make the parasitic buffing game pan out. When he has to face high 2HKO magic off the bat, the odds of it are rather slim.
Vampire vs Indalecio (SO2) - On the other hand, Indy doesn't have the pressure to really threaten Vampire (3HKO damage at base means White Wind is still workable). Once all the buffs and debuffs are fully in place, it's smooth sailing for Vamp (he can survive a post-ToT Indy turn and -barely- has the damage to blitz it through after proper chipping).
Vampire vs Groudon (PKMN) - Battle Thirst.
Vampire vs Luc (PC form, S3) - EDIT: Funeral Wind is faster than Vampire. Tough luck.
Vampire vs Legretta (TotA) - Legretta doesn't even resist Fire! And her pressure at full HP is what we know. Yeah, you really don't want to be a pure limit boss against Vampire.
Vampire vs Georg Prime (S5) - Georg's mdef is so awful the status resistance doesn't even matter. Charm's probably enough to buy Vampire the turns needed to apply his game, since he can just refresh it and all that jazz.
Vampire vs Nash Rumack (Lunar:SSSC) - Way too much status here and, unlike what happens with Knight, Vampire -actually fears- Silence.
Vampire vs Meliadoul Tingel (FFT) - EDIT: Vampire goes in only equipping a shield and buffs defense. Then, Chomp until 1 HP => Bone Crush at worst, and Battle Thirst, even against shield evade, should see use.
6-5. Very weird performance. Vampire's game is quite dense and methodic, which means he's not very well off when under pressure. It's quite brutal against pure limit fighters, though (see Indalecio and Legretta failing it up). Some issues with limited buff/debuff duration also come into play (the Indy fight is actually harder than it seems, since Vamp has to keep up both a M. Atk. bust and an Atk. buff, for instance).
Lassic (PS4) vs Lambda Zellweger (WA4) - Lambda feasts on the slow. Lassic's durability makes it worth thinking about, but don't think three Another Gates are enough.
Lassic vs Genevieve (VP1) - Lassic has the wrong damage type for this and Contaminate Energy does -horrible- things here. So does landing any of his possible weaknesses.
Lassic vs Athos (FE7) - Again, wrong durability to hit and Lassic can't even exploit doubles. Nosferatu works its magic.
Lassic vs Yaridovich (SMRPG) - THUNDER HALBERD actually might be a viable strategy here! Think he has enough HP for this, but obviously could be wrong.
Lassic vs Indalecio (SO2) - Lassic can chip-3HKO to minimize the ToT offense, and he should survive one non-ToT and two ToT Indy turns. If he has Explode, though, this switches around if you allow the damage cap to overflow.
Lassic vs Groudon (PKMN) - Hits the right durability, yeah. Rest doesn't work here.
Lassic vs Luc (PC form, S3) - Okay! I believe Luc's faster than Lassic even with Wind of Eternity. So, he opens with that. Afterwards, Lassic should 2HKO with Another Gate, so he goes to Shining Wind until it runs out and finishes with his last Wind of Eternity. This clocks in at roughly 3.69x PC HP... which is probably enough to handle Lassic to me. Not by much, but enough.
Lassic vs Legretta (TotA) - Lassic can't avoid Legretta's first dangerous ranges and can't chip-2HKO off -that- defense. If he opens with Another Gate, he eats 3x PC HP worth of holy damage off Prism Ballet -alone- and she can actually combo into it with something else holy (even if OK doesn't note it, I once had her comboing into it, so I'm going to trust my experience here), leading to a bizarre occurrence where a PS4 boss gets OHKOed. However... he only reaches her Searing Sorrow range after his second turn if he chip-3HKOs (and that I'm fairly confident he CAN do), and he survives two turns of scrubby Legretta offense+a Holy Lance combo. So it goes. Interesting match.
Lassic vs Georg Prime (S5) - Another Gate against Georg mdef. Dear god.
Lassic vs Nash Rumack (Lunar:SSSC) - Nash and bosses.
Lassic vs Meliadoul Tingel (FFT) - Meliadoul in a pure slugfest.
7-4. Pretty predictable. Lassic's strengths and weaknesses are pretty well-known and have been for a long time.
Hilarious fact of the day is Luc sweeping the contestants, though.
