Tailpipe & Pinpointer (Transformers: Human Alliance; Hasbro; 2011)
Of the handful of Human Alliance toys that I bought during the DotM toyline, I think these were my favorites. Tailpipe is dynamic and has a unique head sculpt, and Pinpointer was a cool bonus.
The only problem was that Tailpipe is pretty far out of scale with the human figures - he’s more to scale with a 3-inch figure, but the Human Alliance dudes are closer to 2 inches. So, no pics of that.
