The third Insecticon has been revealed, and just like the Robot Heroes and Reissues, Shrapnel has been renamed. They've used the reissue name - Sharpshot. I guess Hasbro are sticking with these new names now.

For the Robot Heroes - Kickback, Hardshell, Insecticon.
For the reissue set - Kickback, Hardshell, Sharpshot.
And now for FoC - Kickback, Hardshell, Sharpshot.
