Thomas is an Assist Trophy in Lawl X. When summoned, he slides across the stage from the left side to the right side, causing damage. If no one is hurt, a giant Thomas face will appear and make the infamous "DUNNN" sound, obscuring the majority of the screen and cancelling out all sound and music for a few seconds.
