CrystalBot is a Power Sphere that first appeared in BoBoiBoy Movie 2, giving Hang Kasa his powers and a suit when activated. Not much is known about it as it was only mentioned by Hang Kasa for a brief second in BoBoiBoy Movie 2.
In a flashback scene in BoBoiBoy Movie 2, Hang Kasa mentions that he and Retak'ka found CrystalBot and GammaBot when they were kids. Hang Kasa took CrystalBot while Retak'ka took GammaBot. CrystalBot was the one who granted Hang Kasa his powers.
The CrystalBot is shaped like a pentagon and is green. His face is flat and gray. There is a crystal elemental logo on the center of his forehead. When inactive, the CrystalBot is stored inside the shield. Part of his head was seen, like headgear, head coverings for the Malays.
In the comic version, CrystalBot is spherical.
