>How did he stay so weak after all this time?
There's no proof he's that much weaker than Yamcha or Tenshinhan, especially if you look at the few feats he does have in Super (or even Heroes). And if you look at the Moro arc in the DBS manga, Chaozu was taking the same amount of damage from Bikkura Quoitur and Zauyogi as Tenshinhan and Yamcha were. Hence, his durability is at least comparable to theirs.
