Larrup is an Ultimate Form Spectrobe. He is contained within the Hammer Geo.
Larrup comes out of a void and has a small-like head. His legs are short and are attached to a rock platform. The hammer he wields has a small dink on the bottom.
- Spectrobes - "Larrup is the czar of destruction. The hammer he wields pulverizes anything it descends upon. There is no foe that can withstand his catastrophic might and force."
- Spectrobes: Beyond the Portals - "This ruler of ruin can knock down any opponent with one mighty swing of its hammer."
When summoned, first a boulders fly out then Larrup emerges from a portal, then raises its hammer and slams it down upon its enemies.
- Larrup can also be unlocked using the Card Input system. However, this can be done any time in the game.
