I believe the captain commander, ukitake, and kyouraku would still be able to beat Ulq. If we had any idea of unohana's fighting abilities, i might say she could, but weve seen jack shit about it... I doubt that the other captains could.. Kenpachi would be close though, but he might let himself get cut up too much and end up losing because he wasnt going strong enough to begin with.. Plus i think if ulq fired his lance right next to him like he did against hollow 2 hed be raped.. I doubt byakuya and hitsugaya could take him, and mayori would need some luck and his epic poisons to defeat the perceptive ulq.. But i doubt he could pull it off, his regen abilities would help, too.

All other people that could beat him arent captains anymore...
