It seems like there might be a bit of confusion regarding the characters and their roles in "Power Rangers SPD" and "Power Rangers Operation Overdrive."
In "Power Rangers SPD," the main antagonist is Emperor Gruumm, while other notable villains include Broodwing, and various monsters of the week. Malik does not appear in SPD.
In "Power Rangers Operation Overdrive," the main villain is indeed Magma, who is the leader of the villains. Furio is also a significant villain in Operation Overdrive, but he is not the primary antagonist. Instead, he serves as a henchman to Magma.
