April Stewart is a member of Funky Phantom's gang.
April Stewart almost resembles Alice May.
Scooby-Doo! Mystery Incorporated
Scooby and the gang headed to the Mystery Solvers Club State Finals. Scooby met Speed Buggy, Captain Caveman, Jabberjaw, and Jonathan Wellington Muddlemore (aka. the Funky Phantom). Among Muddlemore's team was April Stewart. Lord Infernicus appeared and captured everyone (except for Scooby and the sidekicks).
Scooby, Jabberjaw, and Captain Caveman saw a letter that showed a ship at the docks was leaving and heading to Africa. They went after Infernicus in Speed Buggy, and forced him to stop his truck containing the kids by throwing guinea pigs at his windshield. Jabberjaw got Infernicus wet (putting out his flames) and Captain Caveman used his pterosaur and wrapped Infernicus up. The meddling kids were released. The sidekicks had solved the mystery.
Scooby unmasked Lord Infernicus. Infernicus was Jonathon Wellington Muddlemore, the Funky Phantom. Muddlemore was sick of being a sidekick. He wanted to be the headliner and leader of his own sidekicks and decided to use the opportunity of the Mystery Solvers Club State Finals to make his move. He wanted to send all of the mystery-solving gangs to Africa.
Funky Phantom used a hologram to make Infernicus appear and fly. A little smoke, fireworks, and a skeleton puppet were used to create Lord Infernicus in other situations. Funky Phantom even captured his own cat, Boo.
Muddlemore also admitted he wasn't a real ghost. When April Stewart and her gang found an old clock, he used special effects so they thought he was a ghost.
