Oh yes. Dende's power level is probably lower than mine, but in battles he's just as vital as a super saiyan
I was wondering... what ever happened to Yamcha and Tien? Are they even still alive?
BTW, am I seeing right that Goku has the mark of Vegeta's (Aladjinn's) hand on the neck?
Yamcha was seen in Chapter Zero talking to Vegeta at No.18's party, and Tenshinhan is still alive as well.
And yes, the Reiki Extraction process has "burned" Vegeta's hand print into Goku's neck.
