Lt. Acklay is one of Commander Thire's most trust worthy officers and has been known to carry out single-trooper missions on behalf of Thire. Acklay got his nickname after stopping a rampaging acklay that escaped from the Coruscant Zoo five months into the Clone Wars.

*sidenote* I created Acklay some time back as a custom figure: http://www.furaffinity.net/view/2079486/

I changed his design to a degree as well as changing his rank.
