Piranha (Archie)

The Newtron is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It is a piranha-based Badnik variant created by Dr. Ivo Eggman.

Early actions
A number of Piranha and other Badniks were left behind on Isolated Island following a thwarted operation of Eggman's, and were modified by Dr. Ellidy to help him maintain the island.

Spark of Life
When the evil computer virus Phage infiltrated Ellidy's systems, she took control of all the Badniks to aid in her attack. Several Piranna were charged with guarding the island's Lake of Rings, and tried to prevent Tails and Big the Cat from obtaining the Chaos Emerald that had landed in it. They then joined the Badniks and the Dark Gaia Creatures attacking the pair, but were later freed by Phage's defeat.

Trivia

 * The Piranha is based on the beetle-based badnik of the same name that appeared in Knuckles' Chaotix.
