Spidertron is a single spider monster created by Finster. He serves as the main antagonist of the episode "Itsy Bitsy Spider".
He is voiced by Tom Wyner
Spidertron was created by Finster. Rita hid Spidertron on Earth inside the statue of the Forest's Spirit in the park. The monster was tasked with putting a sleep spell on everyone who came near it. When Zack with his students came to the park to study karate, all of them, except Zack, fell under Spidertron's spell.
Spidertron then emerged from the statue and attacked, where it was revealed that Zack had an overwhelming fears insects, especially spiders. However Black Ranger managed to overcome his fear and helped his friends to defeat the monster on the ground with his Power Ax. Rita then enlarged Spidertron.
As a giant, Spidertron could fire energy web and multicolored lightnings. The Rangers formed Dino Megazord and were able to fight him, but after an intense attack, they were separated back into their individual Zords. The monster managed to reflect the Mastodon Dinozord's Freeze Spray and Tyrannosaurus Dinozord's jump kick attack.
He even trapped Dragonzord in his web. However, Mastodon, Saber-Toothed Tiger Dinozord, Triceratops Dinozord combined for the first time with Dragonzord, forming Dragonzord Battle Mode (Tyrannosaurus was assisting and Pterodactyl Dinozord seemed missing). They finally destroyed Spidertron with Dragonzord Battle Mode's Power Staff drill attack, perforating a hole in his midsection, causing him to fall and explode.
Spidertron was cunning, sneaky and unpredictable monster, like many other monsters of Rita. He also doesn't talk, only speaks in whizzing. He was shown to be quite skilled and capable fighter, as he managed to divide Dino Megazord on many individual Zords. He possessed great affection on Zack, due to Black Ranger's phobia of insects, but the hero eventually defeated his fear.
