Although it's true name is currently unknown, the Bull-Head Mech is a mech seen battling Saki Rukino and her RM-047 Valvrave IV Hinowa in an asteroid field by an unknown gas giant in the 214th year of the Third Galactic Empire; It is piloted by the Unnamed old man. It appears to be a descendant of the Erpf129-z5 Kirschbaum as it has a similar basic structure and comparable transformation system.
All of the Bull-headed mech's weapons fire a beam fire a similar to that found on the Waffe's Duquennoy Beam Cannon.
- 2-Barreled Beam Guns
- The feet and "hands" of the mecha are two barreled beam guns.
- Wing Beam Cannons
- On both of the wings are long barreled beam weapons.
- Chest Beam Weapons
- A pair of eye-like beam cannons that need a few moments to charge before firing, it is likely the mech's most powerful weapon.
- Transformation System
- Like the Erpf-129-z5 Kirschbaum it has a transformation system, unlike the older primate frame the Bull-Head Mech does not do a vertical spin to transform and is seen using it's chest beam weapon in it's respective fighter mode.
