Protectos the Goreroid

Protectos the Goreroid (プロテクタス・ザ・ゴアロイド) is the guardian of Area L, a forgotten laboratory. Protectos is a Pseudoroid based upon a rhinoceros. Under his armor, is a fragment of the Biometal Model P, providing him considerable strength and a protective shield. Serpent gave him a mission to recover some data from the laboratory, concerning the Biometal Model W (Model V).

Protectos can attack with a range of missiles, bombs and other explosives, and possesses a very strong defense, due to his very thick armor. Protectos's armor, although strong and able to withstand powerful explosions, is very weak in the head and stomach areas as they house his Biometal fragment. His personality is similar to the likes of Flame Mammoth and Silver Horn, as both are arrogant because they are big, among other things.

Manga
Prometheus sent Protectos and Leganchor to attack the Guardian Base while it was docked in Area G and Vent was far away in a Chinese restaurant. After defeating Fistleo and Hurricaune, Vent hurries to Guardian HQ and fights against Protectos, defeating him with Model HX after discovering that his face is his weak point.

Trivia

 * In Mega Man ZX Advent, Barriode's data says that they have Pseudoroid DNA, indirectly referring to Protectos.
