Pac-Man's smash attacks may have this "trample" property you're describing. When I was in training mode the other day, I had Sonic's Fsmash connect with Pac-Man's Fsmash at the same time. Pac-Man's Fsmash cancelled out Sonic's, who went into the clanking animation, but Pac-Man's Fsmash kept going and hit with the sourspot hit. I think this also applies to the rest of his ghosts.
You're right. I've just looked through the japanese data and found all of these (with trample):
Bowser jr: rapid jab finisher, dsmash, fair-landing, dair-landing |
edit: dsmash beats and hits through other moves
DK: fsmash, usmash, dsmash |
edit: dsmash beats and hits through other moves, but usmash and fsmash don't, fsmash only sometimes? (depends on spacing...?)
Zelda: usmash (last hit) |
edit: tested
Toon Link: dashattack |
edit: tested
Palutena: ftilt, dtilt, utilt |
edit: her tilts are weird. They beat out other moves, but their hitbox won't hit them after the clanks | edit: after the 1.1.0 patch, her ftilt actually can hit after a clank, utilt can work too
Ike: dash attack (first hit) |
edit: doesn't stop, but doesn't hit opponent in the clank
Fox: fsmash |
edit: has 2 hits, if you clash with the first one the opponent can be hit by the 2nd
Falco: fsmash (late hit) |
edit: tested. first hitbox is transcendent
Pikachu: fsmash (last hitbox (21-22)) |
edit: tested
Greninja: usmash (first hitbox) |
edit: tested
Duck Hunt: all smashes |
edit: smashes work fine
ROB: usmash (first hitbox (launcher)) |
edit: doesn't stop, but doesn't hit opponent after the clank
Villager: ftilt, dtilt, dsmash |
edit: tested, dsmash could probably theoretically hit with the 2nd after the clank
Wii Fit Trainer: usmash |
edit: tested
Pacman: fsmash (2nd hitbox (21-28)), usmash (strong hits (16-26)), dsmash |
edit: tested (weak hits will hit opponent after clashing)
Mii Swordfighter: usmash |
edit: tested
Edit: (somehow forgot those)
Mewtwo: Jab1 (and some parts of multijab), Usmash (all hits) |
edit: tested
Ryu: Ftilt (strong) (both hits) |
edit: tested (2nd hit will hit opponent if first hit clashed)
I'll look into them more to confirm each one and see how it works before adding them to the op, but it should all be correct. Didn't include the ones I already have in the op.
