Attacked Earth due to the desire of conquest of the Insectoids and the need to further expand the reach of his kind throughout the galaxy.
Wields the Drake Tomahawk in battle.
Massive axe is never named.
Has electrocuted Buredoran at one point.
Has never disciplined Vrak other than scolding him.
Has an ability called Gravity Fall (which is his deadliest attack) in which he uses the dark matter in his body to cause a nearby satellite to impact the planet he's currently located on. Uses it in Act 12 to make the moon collide with Earth but fails.
No such ability to make anything collide with planets, only going down to Earth himself in his final appearance.The equivalent was Malkor's Cosmic Stream as it was his strongest attack and vaporised the Ranger's Zords.
Mons Drake attempts to replace Dereputa after his supposed death with Targate of the Satellite. But his death, causes him to be so furious, he decides to personally end the interference of the Goseigers with his plan in Epic 15.
Malkor recruits the Toxic Beasts immediately following Creepox's death and it's not until the episodes leading to their defeat does Malkor decide to go to Earth himself, but calmly enters his power-increasing cocoon first. Targate does not have a counterpart.
Admiral Malkor is, unquestionably, the second most powerful warrior, and villain, in Power Rangers Megaforce, drastically exceeding all of his allies (With the exception of Vrak and Mavro) and being on a class of his own even before cocooning.
