Tyrine

Tyrine (ティアリーン) is a mini-boss Mechaniloid from Mega Man Zero 4. It appears in Sol Titanion's stage, Artificial Sun. It has eight GlassCannons revolving around it that shoot energy spheres. After a while, it will start shooting spheres from itself. If Zero destroys all the GlassCannons, it will fire energy spheres non-stop in a circular pattern. 

GlassCannon
GlassCannon (グラスキャノン) is the name of the eight Mechaniloids that move around Tyrine.
