Dynamo proves a good point too, IIRC, because it's not some sort of canned or special animation.. it just runs, even on dead bodies/nothing. It's not like Val EKG.
SBO will juggle a body but by the time you've done it you will enter the finishing animation after recovering, so no multiple chaining them, but she does have a stall similar to bella's with jMP's and sjs/djs and then a final divekick. HDive can be cancelled on hit into SBO (the first hit or the second, only the first will trigger on dead bodies, IIRC, so you could HDive > SBO a dead body, but i don't know if you could have time to do jMP stalling before doing that)
Even Gregor ends soon if it doesn't hit anything. Hmm.
Clearly whoever can stay in the air the longest, in whatever way, has the most time for BMing. Bella and Val tie for first and Squig gets last. Bella's jHP into grab bag tech do stuff... stuff. Bella ritual is a thing. It negates the downside of her not even having an air super to stall with. Val comes second for best stalls with air supers and mobility. I put Squigly over Fortune becaues I feel like the jMP stuff lasts longer than any way fortune can air stall except jump double jump air dash. Plus the SBO bounce is pretty rude and lasts even during Squig's win animation. Fortune's air super will also bring her to the ground, but you might get a sneeze or a nom off it if the full thing hits? Dunno.
im not sure how long painwheel is allowed to fly
squigly can't do stance move except DP for whatever reason, I think to prevent some sort of stall with stance moves/walking, but DP seems to work anyways, at least I remember H working, might have to do with its special priority
painwheel had a buer loop BM infinite IIRC and so now buers don't act the same on dead bodies.
big band timpanis are a good contender yeah
idk how double moai head works out
big band level 5 and do nothing is pretty BM worthy, just making them sit through silence while 5 bars runs out
its hard to get the good BM without it involving the kill, post death BM is just not as good, it's been shortened a lot (thankfully!) but pre-death BM strats always seem cooler. like doing beo level 3 or eliza air super into double's monster puddle so they fall for a reaaaalllly long time. when val got limited to 2 air bypasses per jump, she didn't lose her scalpels dead body BM combos, they just changed
also dead bodies DO act differently, so if you're into stylish BMing via combos impossible otherwise, you can rock some stuff that normally doesn't work based on.. well.. how dead bodies act.
