Hedgeshock the Erinaceroid

Hedgeshock the Erinaceroid, known in Japan as Tesrat the Hedgeroid (テスラット・ザ・ヘッジロイド) is a small Pseudoroid based on a hedgehog. She is found in high-power generator coils, as she was originally designed to serve as an emergency power supply at key installations. She is equipped with a powerful electric-generating coil and her hands and feet have the shape of sockets. By reducing her size, she can squeeze into small places. She talks hysterically and acts like a baby. She is fought at the Mysterious Lab.

When playing as Hedgeshock with Biometal Model A, the only abilities that Grey and Ashe lack are based on her battle arena: summoning a New Rattrap and filling part of the room with water. The player can still use her spark attacks and rolling dash (both with extended spines and without) to damage enemies.

Trivia
