The prototype for Signal made by Otoi-sensei and Masanobu. Originally he was seen with silver hair and a grey styled outfit. He was a very kind and gentle robot but then one day Masanobu made some changes, upgrading him into a highly skilled combat robot. His look then changed to black long hair and dark clothes with two massive blades connected to his arms. It also appears that he conducts electricity through his hair and then charges that power through his eyes like a laser. These changes were not entirely for the best. Now he seems to be VERY nearsighted and if he should happen to use the laser or get too worn down he passes out. He has what appears to be robotic narcolepsy. He and Signal constantly fight and tease each other, but Pulse seems to have a soft spot for Chibi Signal and often talks with him. It also appears he was/is friends with Kris.
