From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Kakuja (カクージャ, Kakūja) is a member of Slugg's Demon Clan.
When Gyoshu, another scientist, was asked by Slugg how long it would take to "fix" Planet Earth, his answer (10 days) did not satisfy his leader and he was swiftly killed with a Ki Blast. His successor, Kakuja, said he could "fix" Planet Earth in less than half the time that Gyushu had said (three days). Kakuja was unintentionally killed by Slugg when the Namekian accidentally blasted his own spaceship when he was trying to hurt Son Gohan.
Kakuja is of the same race as Gyoshu.
- Kakuja has a more serious and evil tone, while Gyushu seems to have more of a coward-like attitude.
