PCX-155b CHELIPEDS (Ares)

Large custom heavyweight arms designed by the PentaCore Conglomerate to supplant the earlier PCX-155a CHELIPEDS, arms first used by Ares, leader of their Mecharus Ground Forces.
Combat data retrieved from Quetzal Militant Technologies' Drones would allow the designers of the previous PCX-155a CHELIPEDS to increase armor resistance, install new built-in weapons systems, and increase compatibility with weight intensive weapons.
These arms are further distinguished from their predecessors by large shoulder protrusions designed to instill authority over lesser Mecharus and massive claw units that can deploy over the normal hand components.
The PCC gifted the entire set of KARKINOS-1b Drone Parts upon Ares' failure to completely decimate Quetzal Militant Technologies' base.
