Jiren’s been on a roll and even Gohan won’t be enough to stop him here. Jiren is easily one of the strongest characters of all time. Aside from characters with fusion as an option I dare say that at this point only Goku can take him down from the DB universe and counting other characters that list may only jump to 3. Jiren is a top contender and while Gohan won’t go down without a fight, it’s hard to really see him dealing much damage here. Once Jiren gets serious then it’s all over. Jiren wins.
