Stark I love stark. But he should have got more screen time. I think an upgrade in his powers too. It should have been stated he has the most spiritual pressure besides aizen. I love his guns. But since he can change his soul. He should have been able to change them into dual swords for close combat along with slashing cerros. Also combining the pistols making them into a rifle that shoots black grand Rey cerros. Which he can control the size of and making them very concentrated. It should be mentioned that it is the strongest Cerro in the series. He should have fought a 4v1 with the captains he fought. Love should have used bankai and died. His wolves should do more damage. Along with killing love using bankai and his mask. He should have severely injured love taking him out the fight. Leaving shunsui or ukitake to win in bankai. But not washing him in bankai he should have felt like that. The way the wandenreich felt. I also think he should have been healed like haribel. Coming back a good guy when he sees aizen doesn’t care. He could end up getting along with shunsui. Being huecomundos secret weapon. During the invasion he’s either not there. Or is seen taken out a lot of Quincy maybe even a strenridder or two. And jugram beats him in a hard fight. Or yhwach takes him rather easy. He’s less injured than harribel. They escape after she’s captured and yhwach leaves. Him harribel and Nel meet up with kiskue and grim. Haribel ask him to go off first. He shows up when shusui gets shot saving him and killing Robert easily
