Character History

Roidmude 103 was among the Roidmudes to attack during the Global Freeze phenomenon. Six months after, he was sent with Roidmude 037 to accompany 024 in arson operations. He firstly fought Drive and Kiriko before his leader, 024 evolved to Volt and escaped after the loss of 037. He was nearly punished by Mashin Chaser, had not Volt bring up an excuse. When Shinnosuke and Kiriko entered an abandoned warehouse to attack them, they were quickly outsmarted by Drve's Type Technic's calculation prowess. He was thrown away by Tridoron Type Technic using the Fire Braver Tire via Tire Enhancement, but he was able to escape the fight and gave Heart the component for Volt's device before fading away from his injuries, both body and Core.

Advanced Camouflage
Roidmudes can generate disguises through film-layers around their body that function similar to the cerebral cortex.
Data Mimicry
Roidmudes can transform their bodies into data to travel within the electricity/cyberspace while in their Core modes. They can as well temporarily morph their bodies into data to easily phase through solid objects.
