Huh, it didn't occur to me the first time I read this, but I just looked at the Trainer data - it looks like aren't
supposed to be any NPC-owned Veluza with their HA (Sharpness) in the first place. o.o
I did double-check the raw data in case I messed up the sheet somehow, which is always very possible - it looks like this is public now, so looking
here and
here, all eight Veluza are either fixed to slot 1 or random between their non-Hidden Abilities. That should completely eliminate Sharpness as an option unless things are working differently than we expect...
This is also strange because the move's damage internally appears to work more like Substitute or Belly Drum (it's hard-coded into the move effect and appears to be a prerequisite for even attempting the rest of the move).
At first, I took at face value that it was just an oversight on the assumption that it was a "negative heal" like Mind Blown - Mind Blown-style recoil is the same column as Heal Pulse's healing, which
is known to be affected by Mega Launcher, so I thought it would make sense for the same column to be modified by an equivalent Ability even if it were a total accident...
but since it
isn't that column, and in fact the datamined move table doesn't do much to indicate how much the move is supposed to damage the user at all, it is quite a lot stranger to me for this interaction to slip through the cracks unless it was for some reason intentional.
So uh, just to double-check - how confident are you that the Veluza in this interaction had Sharpness at all? Is it possible that the move itself works differently than we thought/that the amount of damage it does to the user can vary, even on Mold Breaker variants...? or can anyone test that HA Veluza do exist on some enemy teams (should be possible to say with confidence because Mold Breaker has an activation message and Sharpness doesn't)?
