Trivia
In the Trivia section, it says:
"Mr. Satan, Tien Shinhan, Chiaotzu, and Yajirobe are now the only known humans left alive on Earth (not counting the half-Saiyans Trunks and Goten)."
We don't actually know if Yajirobe is alive as we didn't see if he dodged Buu's Human Extinction attack or if it got him.er
