He supports Professor from afar by using remote-controlled animal robots from an emergency shelter known as the Summer Resort. He has been described as a hacker and he can use his remote-controlled machines to communicate with the Professor.

His shelter is later flooded, presumably by SCHOOL, and he is trapped there. Realizing that he is going to be trapped, he requests help from the only surviving teammate, Xochitl, but she refuses, saying that she scorns the idea of having to clean up for MEMBER when she wasn't that involved with them in the first place.
