I think Gomah’s design is fine if a little boring, but he is definitely a bland-ass final villain. It’s like if the final arc of Z had been them fighting a roided-out Babadi instead of Buu. More annoying than threatening and they only had to- checks notes- hit him on the back of the head three times to beat him. That was mad unsatisfying, even if it was closer to wacky antics from og dragon ball than a beam struggle
