ASCII Oakley is the main antagonist of the "ASCIIng For Trouble" event in Snake Gultch, part of Champions Online.
ASCII Oakley may look like a stereotypical Western hero but, like most of the other Cowboy Robots, she is, in fact, a murderous and corrupt A.I. who sees humans as an intrusion to her "town".
In order to lure the dangerous robot out, player heroes defeat her robotic minions; eventually, this angers her sufficiently that she arrives on the scene to challenge the heroes to a shoot-out.
It is at this point ASCII Oakley is able to be confronted and, with luck, defeated by heroes before the time runs out (events in the game are timed- which means it is important to defeat ASCII as quick as possible).
