<p>It looks like a Psi, but it seems to be more closely related to a pitchfork.  :)  See <a href="https://stats.meta.stackexchange.com/users/6064/seth-rogers">Seth Rogers' profile</a>.  Looks spooky to me and he's with a shady group called "CHAOS", an "evangelical" group operating behind the scenes.  (Oh, and Halloween is just around the corner.  Boo!)</p>

<p>In all seriousness, does anyone want to explain the choice of Psi?</p>

<p>Update 1: <a href="https://stats.meta.stackexchange.com/questions/936/who-is-this-person-with-a-character-and-what-is-the-chaos-team">This page</a> has a bit more background on the pitchfork brigade.</p>
