He can just break by hitting the ground
Aye definitely. The literal fall of a titan. The fall of a hero. He could end up falling over or being pushed over by BB or Shiryu, the latter who is there and has done nothing but probably going extreme diff with Tashigi offscreen clearly /s. (Wtf are those 2 actually doing? lol)
Seriously though, Oda could truly pull a tragic scene here if he wanted to. MHA has been teasing the "brutal, tragic death" of All Might for YEARS now but its always been blue balling/bait.
Now AM is pretty much helpless and still trying to fight AFO who is back in his prime effectively and this should be where AM dies his tragic, brutal, heroic death as a final stand and AFO getting revenge on him but Horikoshi took the ol'mangaka bait and cut away from it for ages now.
Oda could make up for that with Garp, as Garp is an All Might sort of character WAY before AM even existed and Garp being the "Hero of the Marines", him dying to a former student and thus former Admiral that he trained/inspired and owes a HUGE debt to him too would be very fucked up and tragic.
For all we know, Kuzan might just snap and want to kill him, showing how far he's fallen to the "dark side" and become corrupt ironically. That would be far more shocking and interesting than the cliche Kuzan is a spy theory and far too common cliche.
I see Blackbeard rocking up and killing Garp, well finishing him off like he did to Whitebussy I mean Whitebeard before. Taking the kill so tos peak, kill stealing.
Honestly I hope we see more of their fight ASAP, its a literal top tier fight and getting to see both an Admiral and Garp going all out and Oda had to cut away from it SMH lol.
