I found Cyberverse Legion Twinstrike today at the TRU near Cumberland Mall. He's definitely a great little figure and looks great with the rest of the Predacons.
Also, there's a facebook TRU coupon for 20% off one item, but it's only good until March 9th. So, I was able to get him for less than $6!
I highly recommend taking advantage of this offer! Nothing else of note at that TRU though and I think got the last one, but I only checked one row of the legion class figures.
