Drum Character Facts

Drum is King Piccolo's fourth son following his release. He is a large, ogreish, frog-like Namekian. He very much resembles his brother Tambourine in appearance and outfit, with the exception of a more emerald shade of green skin and the lack of wings, as well as being much larger than Tambourine, with his structure being like his other brother Cymbal. 
Even though he is the shortest-lived son of King Piccolo, up to this point he was the strongest since King Piccolo created him when he was in his prime. King Piccolo spits him out just as Tien Shinhan arrives to try and trap King Piccolo in the Evil Containment Wave. Drum attacks Tien, and clobbers him quite easily, and at one point almost traps himself with the technique. 
Due to being born while King Piccolo was in his physical prime, Drum is the strongest son of the demon king, bar Piccolo Jr. He easily defeats Tien Shinhan, whose power level at that point is 180, but is killed in a mere two hits by a newly powered up Goku, whose power level is 260 at that point, equal to King Piccolo himself.
