I cant edit the post so Ill put the write up here
Flash: Beats sonic pound(even if meter burned), beats f3, beats b3, trades with flying upper, beats running man stance overhead
Nightwing: Beats flip kick(even if meter burned), beats flying grayson, beats f3 in escrima stance
Batman: Beats f3, beats b3
Lobo: Dont have so I couldnt test. If any lobo players would like to help me test and run some sets that'd be nice
Joker: No finds
Harley: Beats f3
Cyborg: Beats techno tackle
Green Arrow: No finds
Superman: Flying ground smash obviously, no good finds
MMH: Beats b3 at a very strange timing, will get into that later
Zod: No finds
Lex: No finds
Catwoman: no "solid" finds, needs more testing
Death Stroke: Beats f3
Raven: No finds
Aquaman: Beats f3(funny side note, jump 1 stuffs un meterburned f3 and b3 with a hilarious kick in the face)
WonderWoman: Trades with instant air amazon smash, beats f3
Zatana: Beats f3, beats arataz evid(the dive kick)
Ares: Beats god smack(meterburned god smack eats up the hit of the grab, something I will go into more later, so his reset must be stopped come other way)
KF: No finds
DoomsDay: Trades with supernova
HawkGirl: Beats f3, beats heavenward stomp obviously. Something else to note in this matchup, if you read wing evade as a wake up and you do a WCC you will end up behind her and able to punish with the 50% of your choice fo free. Dont see many hawk girls wake up with wing evade though
Shazam: Beats the normal overhead b2
Green lantern: Beats f3, which is really great for the GL MU inside sweep range because now we only have to block low
Sinestro: Beats axe of terror, no good finds
Bane: Beats f3 and b3
Batgirl: I dont have so I couldnt test. If any batgirl player would like to help me test and run some sets that would be nice
Now a few things about this ive noticed/want to discuss. In the martian manhunter test it seemed I grabed him right out of his b3 when I hit it at a certain spot. This and another factor Ill bring up in a moment makes me want to believe that this anti air grab isnt so much an anti air grab, but a command grab with a certain range(much like GL's lanterns might). I noticed in and infinite practice sesh today that the grab on hit connects as a mid first for 1% not a throw, then follows up with 10% unblockable damage that is the opponent being thrown to the ground. From what I can gather anything that enters the hitbox for To the Grave will act as if it has taken a mid hit, and if that hit would stop whatever motion is being done without trading with grundy at the same time or hitting him first then it is followed up with the throw to the ground. This leaves much more room to build on this list with any normal strings that might step into grundys air throw hit box. This could also be quite beneficial to the doomsday forum because his air grab seems like it functions similar to grundys. Also To The Grave beats these special moves on wake up as well since the invincible frames dont last long enough.
