Appearance
Before his transformation into a robot, he looked like a meteor. Sometimes, an arm attached to certain tools such as spinning blades and laser guns, appeared behind his back before Spell & Speak destroyed it.

In his robot mode, he was a blue and grey robot with parts of his "alternate mode" on his back...
