Onigiri

オニギリ

Also known as Analog in the English dub.
Arashi meets Onigiri in Episode 7, and after the events in that episode, Onigiri joins Team Freedom. Onigiri is a "boy professor" and is very knowledgeable/passionate about Zoids. He was initially developing the technology required for Death Metal to use their Death Blast, but was reluctant to do his research due to the harm it caused the Zoids.
