Pteraxadon seems to be a reimagining and new name for Action master Take-offs partner Screech with a new weapon mode. The Original had a Huge head and turned into a helmet.

Not too keen on prowl. The other two are quite interesting

 

I don't know what it is, but something about Prowl looks... off? Either way, I was planning on sticking with CW Prowl, so...

 

Ooooooohhhhhhh!!!!!!! I'm really liking that Six-gun.  

 

It seems the bitching and moaning about the battle damage has gotten to Hasbro since the one on Prowl seems to be minimal.

 

These are just renders though. Seems to be the battle damage is reduced on all the renders vs. the actual figures.

 

So...besides Barricade who else is Prowl going to get reused as? Lancer? Greenlight?

 

And as I said, Prowl is rather plain.

 

Prowl does look a bit off, but he's leaps and bounds better than U2.0 or CW (imho). Hopefully we get his brothers in this mold, too, one way or the other.

Pteraxadon looks good. Nice variety on battlemasters.

Sixgun looks like a lovely army builder. He, Brunt, and Cog are going to be all over my collection.

 

Prowl sure is um something. Bot mode is okay, it certainly looks like him even if the vehicle mode is different. Vehicle mode though I have to say is UGLY! It doesn't even feel cybertronian, it just screams really ugly concept car. Also those damn translucent wheels. WHY!?!?!?!

Pteraxadon.......just a wee little Pteranadon that turns into an axe. What's not to like?

Sixgun though oh dear lord that is just pure sexiness. Oh he is just so glorious. I must haz the precious.............

 

  I need that Prowl and Sixgun!

 

Hopefully Six Gun will be able to attach to Metroplex.

 

Prowl looks like it could stand pretty well.

Fingers crossed for an ankle tilt.

I'll skip Prowl and wait for the Barricade redeco. The other two look good.

 

Thanks, they look great !

Six-Gun has a kind of "Achilles" Robotjox vibe to it.

 

Definitely in for all 3 of these. I’d expect prowls mold mates at some point during the trilogy in part because the light bar was intentionally made removable from the core figure
