Gus, also known as "Pulse," was a member of the Mutant Underground. Pulse was apparently killed by the Sentinel Services when the Underground helped mutants break out of a relocation center. However, Pulse resurfaced as an agent of the Sentinel Services two years later when the Underground attacked a prison convoy transporting Polaris and Reed Strucker to a more secure facility. Once the Sentinel Services suspected they were under attack, they used Pulse's abilities to disrupt the powers of every mutant in a two-block radius. Thunderbird recognized Pulse as one of the Sentinel Services' agents, and fought his former friend to restore the Underground's mutant abilities. Once Pulse was taken care of, Polaris used her own powers to break herself and Reed out of the convoy.
