Emperor Gruumm

Emperor Gruumm, played by Rene Naufahu, is a figurehead who serves as the de jure leader of the Troobians, an alien empire whose ultimate goal is to conquer other worlds. Gruumm is relentless and nothing will stand in his way to conquer the universe. He previously destroyed the planet Sirius (home world of Anubis Cruger), and in 2025 he launched an assault on Earth.

Biography


All that's known of his backstory is that he works for Omni, a malevolent disembodied brain that Gruumm fears and worships as "the Magnificence"/"Your Magnificence".

Gruumm's main strategy is to overwhelm and devastate a planet with constant, large-scale assaults and then drain the planet of its resources, as shown in the flashbacks to the Sirian invasion, and used such tactics on the Helix Nebula simply to draw the A-Squad into an ambush. It's briefly shown that his ship can even destroy a planet from orbit.

Gruumm had conquered and slaughtered a large number of planets, with the Rangers once exaggerating to say he'd conquered everywhere but Earth. In the DVD "Meet The Ranger" features, Kat Manx said that her own homeworld had fallen to the Empire.

His highly destructive tactics show life means little to him. It was initially unclear why he wasn't using such tactics to conquer Earth, except on rare occasions where he simply lost his temper and struck in force or attacked personally; in each case, he would have won if not for outside intervention (new weaponry for Cruger, the Omega Ranger, and Dino Thunder Rangers respectively). It became clear later on that Gruumm had been working off a long term plan, intending not to leech and destroy Earth but instead to use its resources - which he looted over the course of the season - diamonds, gold, Iridium, and Hemotech Synthetic Plasma (which is used as a synthesizing agent) - to construct a body for Omni.

Emperor Gruumm has two aides, Mora/Morgana and Broodwing. He has a bitter hatred for Cruger, who cut off his right horn in the battle for Sirius. He is also the most powerful warrior among the Troobian empire, as proved in his victories over the B-Squad Rangers and Supreme Commander Fowler "Birdie". His main weapon is a staff that shoots energy, and he also rides a motorcycle with laser cannons. Gruumm has the ability to use telepathy and shapeshift into a selected human form. In battle, he has shown the ability to decimate the Rangers, defeat Commander Birdie and also harm Zeltrax, though Cruger has shown the ability to defeat him.

As Omni's master plan came to fruition, Cruger escaped from a cell onboard Gruumm's ship and the two engaged in battle. Although Gruumm was thought to have perished along with the Magnificence, he survived and engaged Cruger (who was unmorphed) one last time, only to get his left horn cut off after being easily defeated. He was then contained.

Power Rangers: Super Legends
He appears in the Nintendo DS version of Power Rangers: Super Legends as the main villain who has set his sights upon the myth of the Hall of Legends, the resting place of the collected energies of Power Rangers across time. In his twisted mind he envisioned a world where his enemy's power is not only stolen, but used to make him a living god over all creation. In the console version of the same game, he is merely mentioned.
