The Geron appear in Metroid Fusion and Metroid: Zero Mission. They appear to be some sort of X biomass, but have visual characteristics like that of a Kago. Geron do not attack, but often obstruct certain areas and serve as a nuisance to Samus, sometimes forcing her to take a longer route to an objective, such as blocking her path in Zero Mission near the Varia Suit. Different weapons are required to destroy different types of Geron, but all can be destroyed instantly with the Screw Attack.
