TFW2005 member Monzo has sleuthed out some of Hasbro's recent trademark filing applications at the United States Trademark and Patent Office.

Autobot Hound
Kickback
Blight
Nemesis Strika
Scattorshot
Wing Saber
Vector Prime
Could just be Bot Shots or Lego Kreo, could just be reclaiming Trademarks on the verge of expiry, or could be new toys. I for one would really, really like a new Strika toy.
