Captain Mutiny is an evil space pirate with a hook on his left arm and the quinary antagonist in the TV show Power Rangers: Lost Galaxy. He takes residence in his medieval-styled castle on the back of the Titanisaur found within the Lost Galaxy alongside the intergalactic sorceress Hexuba in her floating mansion there.
After Deviot cast the Keonta Spell from the Galaxy Book, a portal opened to the Lost Galaxy. There, the Rangers encountered a giant castle on top of a dinosaur-dragon. Inside the castle was a pirate named Captain Mutiny. At first, Mutiny showed to be a sympathetic pirate and even "offering" to help Terra Venture with their problems.
The Rangers did not believe him so they decided to keep an eye on Mutiny and even follow him. Eventually, the rangers found out that Captain Mutiny captures anyone stranded in the Lost Galaxy, and uses them as mining slaves. At one point Deviot actually joined Captain Mutiny's crew as his second-in-command. With the help of Mike and the Rangers, Captain Mutiny's plans failed.
When Terra Venture was exiting the Lost Galaxy through a portal, Captain Mutiny wanted revenge. To get his revenge, Captain Mutiny followed Terra Venture through the same portal. When Mutiny and his crew exited the Lost Galaxy, Mutiny wanted to take over this new Universe. However, as soon as he exited the portal and started to plan on conquering the universe, Trakeena appeared out of nowhere and attack Mutiny's castle. By using the Scorpion Stinger, Trakeena crushes Mutiny's castle and replied; "There's only one ruler fit for this universe, and that's me." Mutiny's castle explodes, killing off Captain Mutiny and all the remaining members of his crew, with the exception of Deviot.
Captain Mutiny is manipulative, and cunning. He actually tries to trick the captain of Terra Venture, by saying he could help them, in an attempt to get them to let their guards down.
- He shares similarities with both his Super Santai counterpart Captain Zahab from Gingaman and the Disney villain Captain Hook from the classic fairy tale Peter Pan.
