Boy, Getting Old is Scary.
When I think of Roshi, I kind of feel bad for him. He’s kind of like a deconstruction of the wise old hermit master trope. Years alone in his hermit hut with just him, his turtle, and a mountain of porno mags, transformed him into what many Zoomers are terrified of becoming, a coomer. This has led to him being so pervy that he has asked a 16 year old to show him his belly button, and got really aroused when she showed him more than that, and he attempted to sneak peaks when Launch was showering as a guest at his house, and he’s done some other thing worthy of the cancellation meme.
But in the end, his redemptive quality is his knowledge and mastery of martial arts. The technique that he handed down to Goku has saved the Cartoony weird Earth of Dragon Ball a thousand times over.
