An anti-monster robotic weapon developed by the TPU.
It is equipped with a retractable claw arm in its right arm, and a TR beam cannon in its left.
When it fires its one-shot finishing attack TR Mega Buster from its chest, the shoulder armor on each side slides on to the chest plate to form the cannon’s barrel.
It also comes equipped with a backpack unit that converts special particles dubbed TR particles into the energy it needs to operate.
The backpack has a vent that sprays out TR particles which enables the Terraphaser to hover and fly, and the particle distribution also disperses electric attacks.
