Metrinen

Metrinen is a fictional character primarily associated with the *Metroid* video game series developed by Nintendo. Created by Gunpei Yokoi and later expanded upon by Bowser Jr. and Takashi Tateishi, Metrinen first appeared in *Metroid II: Return of Samus* (1991) as a minor antagonist. The character is a small, insectoid creature resembling a mix of a spider and a beetle, inhabiting the planet Zebes.

Metrinen is known for its aggressive and territorial behavior, particularly when protecting its nest. Its primary role in the games is to defend the planet against Samus Aran, the protagonist of the series. The creature is often depicted as a nuisance, attacking intruders with its stinger and venomous bite. In *Metroid II*, Metrinen is one of the first major threats Samus encounters, forcing her to navigate its swarms and nests to reach higher levels of Zebes.

While Metrinen does not appear in later entries of the *Metroid* series, it remains a memorable and iconic antagonist due to its unique design and role in the franchise. Its presence in *Metroid II* solidified its place in gaming lore, particularly among fans of the *Metroid* universe. The character’s simplicity and effectiveness in gameplay have contributed to its lasting legacy.
