In Dragon Ball Super Roshi gets back on training and levels up to be on par with the strongest fighters from other universes, which is why I ranked him there. During Z he’s totally rusty and can’t even hang with Dr Wheelo’s goons - although he is stated to be immortal, and that counts for something.
No way Roshi is stronger than those guys after they trained with King Kai
