Assuming a 3 turn average with 1 100 FP move, Aika's 50 IP move does about 1.13 PC HP damage (including Mousse)
Aima (Lufia 3) vs Lenneth (VP1)- Lol yeah. Not OHKOed, only needs to take a little damage to get to an OHKO (assuming Lenneth's defense isn't high enough to kill the OHKO). But sure, chip.
Aima vs Deis (BoF1)- Super, Rub 1 is only 50%! So it misses, Deis eats Paralysis.
Aima vs Van (TotA)- I mean, Aima is good,
Aima vs Elc (AtLC)
Aima vs Albedo (XS1)- I idly wonder if Albedo's halving Max HP move round down (in effect meaning it 3HKOs 50% of the time) or up. Also Aima may OHKO him. My gut is yes, she does. And he doesn't have anything to scare her turn 1.
Aima vs Riou (S2)
Aima vs Cristo (DQ4)
Aima vs Cress (ToP)
Aima vs Rydia (FF4)- I think Rydia is slower, but while Minerva is not technically legal in 4a (which I go by), I think I'm okay with fudging this one a little.
Aima vs Artea (Lufia 2)
Aima vs Georg (S5)- Aima doesn't kill him in 1 hit...unless...he equips for status blocking
Lanselot (TO) vs Lenneth (VP1)- Probably depends on that Parry rate?
Lanselot vs Deis (BoF1)
Lanselot vs Van (TotA)- Can't avoid all the MAs
Lanselot vs Elc (AtLC)
Lanselot vs Albedo (XS1)- Not sure about that HP draining here
Lanselot vs Riou (S2)
Lanselot vs Cristo (DQ4)- Uh...man.
Lanselot vs Cress (ToP)
Lanselot vs Rydia (FF4)
Lanselot vs Artea (Lufia 2)
Lanselot vs Georg (S5)
Ness (EB) vs Lenneth (VP1)- Doesn't OHKO Ness, but does 2HKO. Ness hates having no turn 1 status
Ness vs Deis (BoF1)
Ness vs Van (TotA)- Ness has 2 problems here. The first is that his damage is rather middling. The second is that that middling damage is extremely expensive. So he probably has to fall back on his half average damage physical. So...I guess Van misses out on ever 2HKOing him, so he should be okay.
Ness vs Elc (AtLC)
Ness vs Albedo (XS1)
Ness vs Riou (S2)- Riou can heal lock with a physical, or a double (heal->Forgiver Sign)
Ness vs Cristo (DQ4)
Ness vs Cress (ToP)
Ness vs Rydia (FF4)
Ness vs Artea (Lufia 2)- God, L2 defense is so bad that Artea will drop 180 defense, block Sleep and Paralysis and ID and never run out of MP thanks to the IP MP healing.
Ness vs Georg (S5)
Aima 6-5
Lanselot 5-4
Ness 3-8 (Hates that worse status)
