I know this is a double post, but I've checked and there's a slightly different inescapable combo that does more damage.
SET 6B+K, SET 3K, SET B+K BE, ORB 6A+B (charge and release after ground damage), SET 2B+K BE, SET 6B+K, SET 66A, SET AAB, ORB 6A+B (slight charge, first attack should whiff), SET 2B+K BE, SET 6B+K, SET 66A, SET B+K BE (Timing is strange, make sure orb is at farthest distance before using this move so that the orb doesn't immediately return), ORB 66B, ORB 66A+BB
This combo does 242+dmg without clean hit or added damage from tech attempts (tech attempts add up to 10dmg).
To ensure that this combo was inescapable, I recorded in training and attempted to escape it myself. I did this by mashing 8G8G8G.... during entire combo, then next time with 9G9G9G... next time with 6Gs until I tried every direction. I even switched up the directions in the middle of the combo a couple times to make sure. The only times the combo dropped was when I started out at a farther distance from Viola. This was all tested on Viola herself, because she is one of the tiniest characters.
Anyways, the moral of the story is she has a 100% damage inescapable combo, and no character should have that.
