He seemed to be maybe Spodey levels strrenght wise, with classic wolfie healing?
if that, though in a crossover, he'd probably be slightly stronger than teenage Spidey
As to the healing factor, Banner got permanently paralyzed. Transformed into the Hulk, IIRC Hulk seemed not able to coordinate well, but walked, when he transformed back, Banner had notable improvement...one more transformation and Banner was completely healed
noted increased healing as the Hulk multiple times as well, but not like bullet wounds closing up in seconds either. I'd say more like classic Hawk and Dove healing, but hard to quantify...
