Circus already labbing some stuff, Dark Fate has safe mixups, less damage no restand, but still, having safe mixups is going to be really good since he's pretty slow. Destroyer has more damage, a restand, and mixups are less safe than DF.
Hard choice.
I encourage you to join me with the 3rd variation.
He has mad mixup in all 3 variations but has better damage in 1st.
The 3rd has a few setups that leave grenade under them on wakeup which is +27 to +34 on block and I found ways to force guess after or F21+3 OH into CMD Grab String.
He gets very solid starters with Grenade and it seems he is pretty safe overall he just has to commit to the overhead with unsafe specials.
The unblockable projectile is only 14f startup and you can connect it on 24% combos (so far) and that prevents breakaway and wakeups.
I feel the 3rd is very strong.
The grenade seems to explode at 2second mark. Which is very strong. They made the grenade recovery long enough where you can't use most enders to use its plus frames into F2/F3 but if you end with 12xxBF3B you can on certain setups.
But I do feel variation 1 is the best having much higher damage into restands.
Imo I don't feel the running man into punch is that great midscreen but seems strong in the corner.
Do you know how to initiate the T-800 armor mode? Or is that not in his tournament variations?
