New Galleries: NFL x Transformers Collaborative Steelers Steelsmash and Packers Tundra Prime

Posted by Seibertron Nov 18, 2025 at 11:51pm CST 3,894 views
Breaking the huddle early, Seibertron.com delivers the first full look at Steelsmash and Tundra Prime.

Seibertron.com takes the field today with a rivalry matchup worthy of prime time as two new Transformers Collaborative figures line up helmet-to-robot for an NFL x Transformers clash. The Pittsburgh Steelers and Green Bay Packers both send out their newest cybernetic recruits, and our latest galleries give you a sideline view of the action.

Out of the tunnel comes Steelsmash, the heavy hitter from Pittsburgh who transforms from an official Steelers football helmet into a powerful Deluxe-sized robot. Built like a linebacker and ready to blitz, Steelsmash carries a removable helmet for robot mode along with a small football accessory for those fourth-and-goal poses. He is no stranger to roster changes either, later being recolored into Starblitz and retooled with alternate heads for KC-59 and Tundra Prime.

Across the field stands Tundra Prime, the Green Bay powerhouse rolling out of Lambeau Country. Tundra Prime converts from a Packers football helmet into a Deluxe-sized robot with the same removable helmet and football accessory. With a frame built to weather any frozen tundra, he brings a strong presence to the matchup and shares his tooling history with KC-59, Starblitz, and Steelsmash.

While these two may represent opposite sides of one of football's most storied rivalries, they are part of the same expanding Transformers Collaborative lineup. More than 20 galleries now showcase this crossover roster on Seibertron.com, including Gigawatt, Ectotron, Major Bison, Sonic, Code Red, and more.

These look cool! I'd probably get one, but I don't follow football and am not partial to any particular team... I wouldn't want to get the "wrong" one and inadvertently make an enemy!

If you're a Transformers collector and not an NFL fan, then there is no "wrong one" to get. Picking one based on whatever criteria checks off a box or two for you is all that matters. I'm assuming we're going to get all of the teams at some point. I'll do my best to cover them all for fans of both properties to enjoy.

I personally can't wait until the Lions and Bears get announced/released at some point. I'm originally from the Detroit area but have lived in Chicago half my life. I root for both teams even though they are NFC North rivals.

Cool that the heads can connect to titan class headmasters and unicron. I have all those and though i'm not a big sports guy i'm from pittsburgh and it's such a sports town that everyone's a fan to a degree. Steelers unicron is tempting...

Not a NFL fan, and I'm Canadian (I do shamelessly always bandwagoning the Montreal Alouettes for the CFL playoff though). So these are not what I care about even though I did play the sport for 2 years back in my high school days. I'd be more interested in NHL hockey helmets.

Gotta say, for a helmet-formers the mold is rather well engineered and comes out as normal a bot as can be. Tons better than those mask helmets in ROTB.

Is Habro gonna release a crossover for every NFL team?

Rev up those engines, collectors!

Seibertron.com is hitting the starting line today with two brand new Transformers Collaborative galleries that blast iconic Hot Wheels designs into robot mode for the first time in a turbocharged crossover between Hasbro and Mattel. These figures capture the spirit of classic die-cast legends while adding the mechanical flair only Transformers can deliver, and our latest galleries put both racers under the spotlight with full high-resolution coverage.

First up is Bone Shaker, one of the most recognizable Hot Wheels cars of the modern era. Known for its open-frame body, exposed engine block, and trademark skull grille, Bone Shaker rolls onto the Transformers track as a Deluxe Class figure that converts into the original 2006 Hot Wheels rat rod. The figure comes armed with a stick shift mace, a fun nod to the car's old-school custom build aesthetic. While he is officially marketed as an Autobot, his sculpted attitude, color scheme and overall look feel right at home next to some of the more intimidating Decepticon designs. Our gallery includes comparison shots next to Megatron as well as the G2 Laser Rods, highlighting just how naturally Bone Shaker fits into a darker, more aggressive display style.

You can check out the full Bone Shaker gallery here: Hot Wheels x Transformers Bone Shaker

On the other side of the track comes Twin Mill, a Hot Wheels legend whose twin exposed engines have defined high-performance fantasy racing for more than 50 years. His Transformers version stays true to the original 1969 design with a sleek profile, two massive velocity stacks, and bright racing colors. The Deluxe Class robot mode features arm-mounted engine blasters and attachable exhaust fire blast effects, giving Twin Mill the kind of track-ready energy that feels straight out of a Hot Wheels commercial. His bold blue color scheme also carries a familiar flair for Transformers fans, creating natural comparison moments in our gallery with RID Side Burn and even Optimus Prime.

These two Hot Wheels icons join an expanding roster of Transformers Collaborative releases that continue to bring pop culture favorites into the world of Cybertron. More than 20 Collaborative galleries are now available on Seibertron.com, including Gigawatt, Ectotron, Sonic, Major Bison, Code Red, Steelsmash, Tundra Prime, and many more.

They've released so many crossovers that you can make mini teams now. I think Bone Shaker would look alright next to the Universal Monsters line or the Ghostbusters (or both). And I'll put Twin Mill right next to Sonic.

I think Bone Shaker's gallery wins out over the two because you have him right next to the Laser Rods. Not many people can do that.

Thanks, Gauntlet101010!

And right before that photo, G2 Electro broke while I was carefully transforming him. The Ace Hardware Lube-E was still doing its magic on the gold plastic and he transformed with ease, until I got to his right leg and the silver plastic ball joint cracked. That was nit the part I was expecting to break. I Macguyvered his right hip with some of my daughters clear elastic hair ties to pull off the shots with a broken Electro.

Ouch, that's tragic. Are you gonna try to get a new one or accept the loss?

I think i will try to replace the leg at some point or I might get an extra to keep in each mode. Haven't decided yet. Might just depend on what I come across.
