Galaman

The Great Galamans are Decepticon warrior drones from Battlestars.

Ya know, they really aren't that great at all.

The Great Galaman army are a troop of dispensible drone warriors conjured up by Dark Nova to plague the Autobots. The Great Galaman drones aren't very powerful or smart, but there are a lot of them, and they often wear down their enemies due to their sheer numbers.

Fiction

Battlestars manga

After Dark Nova resurrected Galvatron as Super Megatron, the Great Galaman army along with the Great Novaroid army were used as the bulk of the Decepticons military forces. Once Dark Nova was killed in the destruction of Star Giant, the Great Galaman forces were never heard from again.
