Barbaracle

Barbaracle is the evolved form of Binacle and is known as the Collective Pokémon, representing seven individual barnacle-like creatures (Binacles) that fuse together to act as a single body. With an eye on each palm, it can keep watch in all directions, and its limbs can move and act independently to overwhelm an opponent. It is a Rock/Water-type introduced in Generation VI (Kalos region), inspired by gooseneck barnacles and crabs clustered on rocks along the shore.

The Japanese name ガメノデス (Gamenodesu) appears to combine 亀 (kame, 'turtle' or 'tortoise'), likely also evoking 'game' from a barnacle/marine creature, with possibly フジツボ-related crustacean imagery, capped by デス (desu, 'death'), suggesting a menacing tone. The romaji is commonly rendered 'Gamenodesu.' The English name 'Barbaracle' is a portmanteau of 'barnacle' (the clustering crustaceans it's based on) and 'barbaric' or 'tabernacle,' reflecting its menacing, collective nature.
