The giants would need to have the biggest glow up......
Most of them are much as jobber as the Vice Admirals.
We've got CHILD Big mom going rampages on Elbaf and nothing they could do to stopped her as per canon.
Giant Vice Admiral are used as hyped tool for WB pirates at Marineford and even pre-skip Luffy dropped one of em
Then another Elbaf warrior who's even in Bigmom flashback training since childhood was floored again G2 Luffy at Dressrosa.
The strongest Giants shown so far by portrayal was owned GALDINO.
I think that's the feats of giants so far, I don't think i miss anything.
Truly a horrendous resume tbh lol
I don't know what Oda's gonna do in next arc to reconstruct the power scaling, and right now it seems they already throwing hands with the Gorosei lol.
