Why not just eat a bean each and every time you're gonna die then?! I watched a YT video explaining this stuff and I knew the DBZ characters were godly strong but WHAT THE F- And then Theres apparently a move called immortality. AND they make you stronger in the process.
Which apparently regenerates you NO MATTER the state you're in. Worst part is there's people stronger than that little m******ker. Plus He seems to have an unlimited amount of ki and he can regenerate from basically any attack because that's totally fair, fighting him definitely wouldn't mean you're Sh** out of luck
He can practically do whatever tf he wants, absorb anything get as strong as the person he absorbed and teleport anywhere in the universe.
