Captain Marvel, A debut of beest monster called "Grumble Bee" (1994) - made by rangercrewmedia info featuring the fun of Marvel Superhero as...Carol as Captain Marvel

Grumble Bee was created by Finster for Rita Repulsa, sent to mock Billy after receiving his first "B" on a test. Attacking Billy and Trini, Grumble Bee put up quite a fight, flattening the two Rangers with his powerful sonic attacks. Alpha created a device for Billy to use against Grumble Bee, blowing some kind of foam on the monster, disrupting his sonic attacks. When the other Rangers arrived, Rita made Grumble Bee grow, but he was destroyed by the MegaZord's Power Sword.
