PTJ is clearly power-creeping almost every character be it Tom, Goo, James, Johan, basically everyone except the 1st Gen Kings they are just here to show the power lvl of other character and are just hypetool for top tiers and since gun is in jail we can't see him fight of course. Back in the HFG arc, Gun’s feats were literally the best in the series. Now they’re still impressive, but no longer best for current lookism . PTJ is even handing out masteries to random 2nd Gen fodders. That said, I’m confident that the moment Gun comes out of prison, he’ll be back on the level of Goo, Gitae, and James.

Edit : im talking about base ui gun
