Soloing pretty much the whole verse due to infinite spin

He has powerful hax. But the thing is, he is extremely slow and is probably gonna get blitz and one tapped

Aren't JJBA characters FTL or smth? That's faster than most of the verse alr

Only stands from parts 3-6 are FTL-MFTL. There isn’t really much FTL feats from part 7 onwards. Hell Johnny was shown to even be blitz by 1880 revolvers consistently throughout the story

So what's his best speed feat?

His reaction speed is anywhere below supersonic whilst his combat/firing speed is probably like massively hypersonic or smt (I don’t trust calcs on vsbw)

Probably solos or gets oneshot depending on who’s around him at the start. He probably solos if he has time to get his stand active, because Jojo’s is busted

With infinite rotation, Johnny blitzes up to the Ōtsutsuki‘s
