was watching some dragon ball what if.
And realized that imperfect Cell can go from post fusion Piccolo tier to trashing fused Piccolo in days by absorbing a few city.
Then if he didnt get cocky and absorbed everyone on earth,or even just a few country,perfect Cell would be strong enough to kill Buu and possibly even buuhan.
And by absorbing the likes of Goku,Vegeta etc... maybe even completely overwelm Vegito
Truly the perfect being,just too cocky,those Vegeta cell doomed him.
