It’s Omega Prime from that Robots in Disguise show (as opposed to the other show by that name, for younger kids) — a combiner based on Optimus Prime and Ultra Magnus.

Based on the 2001 Transformers: Robots in Disguise designs, Omega Prime is available now for $250 but will only be released if 10,000 people pre-order in the next 40+ days.

The Transformers x NFL helmet series will consist of four figures initially - Dallas Cowboys Starblitz, Pittsburgh Steelers Steelsmash, Green Bay Packers Tundra Prime, and Kansas City Chiefs KC-59.
