Rigll and the other guard troops were not present at the time of Cold's death and Frieza's first death. As such he was unaware that the Dragon Team even existed, only being aware that Frieza and Cold had been killed upon invading Earth, after having the planet scouted and discovering the "strongest man" Mr. Satan he and the other guard troops chose not to invade until he was dead, as they knew they could not deal with the one who defeated Frieza.
After Mr. Satan's death, the guard troops finally ordered the invasion of Earth in Age 820, leading to a full planet wide conflict and many deaths, and finally culminating in a battle between the aged Z Fighters and the Frieza Force, Rigll survived the conflict and went on to lead the Frieza Force remnants on Earth years later.
Rigll controls the operation from the shadows from his Sky Dungeon. After their continued failings in their alliance with the Time Breakers, Rigll decides to turn on them. He, alongside the Bas guard troop, Burter's race guard troop and Wada, send their troops to loot the Sacred Land of Korin, however their operation is stopped for good by the youth.
- Rigll's name comes from "grill".
