Biography
Drum was incredibly unintelligent, get could still pilot a fighter jet with considerable skill. However, he possessed poor vocal skills and as such could only communicate via making the sound "brrrrr" - except for one occassion when he announced "that's our law" (it's currently unknown what exactly he was referring to).

He was killed by Buster Breaker when him and his brother attempted to kill Sefer Yetzirah before him.
