Psy-tcopuses are enemies in Ratchet & Clank, with a cameo in Deadlocked. They are mutated aquatic creatures resembling squids, octopuses, and plesiosaurs, found in the Jowai Resort, Pokitaru. They have the ability to release balls of energy from their brain, and are found alongside puffoids.
Psy-tcopuses were native wildlife of Pokitaru, mutated by the blarg waste disposal tankers attacking Pokitaru. Ratchet and Clank fought them on land during "Help the resort owner", in which they had to follow the Resort Owner to a jet fighter to destroy the blarg waste disposal tankers.
In Deadlocked, a psy-tcopus cameos in a cutscene, with Gleeman Vox promoted DreadZone, showing a scene of a tyhrranoid soap-opera in which a tyhrranoid groom revealed to his bride that he was not a real tyhrranoid but in fact a psy-tcopus.
Psy-tcopuses are purple creatures with large, pink heads containing an oddly large visible brain therein. They had a circular base with eight pointed tentacles. While on land, psy-tcopuses appeared completely immobile, and would simply charge an energy ball from their heads before releasing it at a nearby enemy.
Psy-tcopuses alone serve little threat, as though their energy blast has long range, it is easy to avoid. They only become a threat when their attacks must be avoided alongside overwhelming puffoids nearby. The best way to deal with psy-tcopuses is to use the Suck Cannon to vacuum in and fire puffoids back at the psy-tcopus. Alternatively, any weapon such as the Bomb Glove, or even the OmniWrench, can be effective as they serve little threat alone.
