So pretty much what the title says. Not so broken though, but close. Beats/avoids jump-ins, beats/avoids cross-ups, beats/avoids mid advancing attacks (Walking corpse). Also leaves WW at advantage in some cases for a full combo punish.
I don't use Wonder Woman but I just saw that she can sweep to duck under all of Green Arrow's low arrows from a distance lol. Even if he does d1 xx low arrow she can duck all of them except lightning arrows. Sorry if this is known.
^ yeah if you guys dont already know her d3 is the LOWEST of profiles. so far ive found it is useful for many things, to name a few I've found: consistent trip guard aa, goes under pig, under ares MB fireball, under shazam psycho crusher...etc
the timing is somewhat specific, and against larger disjointed jump normals such as joker or green arrow j3 it wont work very well, but in general yes you can use it as a trip guard aa
what happens is the d3 hurtbox is low enough to avoid the jump attack altogether and then they land on the d3 active frames and get swept
