O'Brien

Agent Gargon was a member of the Department of Floaters, partnered with Agent Van Dyne and later with Chliever the Corroder.

Gargon, with Van Dyne, recruited Chliever from a Suefic in which Van Dyne was killed. It is known that Gargon was already relatively senior by this point. After Van Dyne's aforementioned death, Chliever became Gargon's partner and the two became fast friends.

The pair avoided the Macrovirus emergency entirely, but during the 2008 Mary Sue Invasion, Gargon was slain by a Villain!Sue impersonating Mai from Avatar: The Last Airbender.
