First - what I like here.
I really like how they managed to take Hot Spot and (literally) turn him around into quite a different looking vehicle. Not entirely sure what this vehicle is supposed to be, but ok.
Without Hot Spot's ladder to help him stand, the heel struts are definitely appreciated, but unfortunately his floppy knees and back pack mean he's still going to fall, unless I don't extend the legs all the way, making him a little stumpier compared to Hot Spot (not necessarily a bad way to differentiate the two) and I don't like how he's permanently looking down (akin to Universe/Generations Ironhide and Ratchet.)
Torso mode is definitely sweet too, new chest piece and rotation of his arms give Bruticus' torso a noticeable different silhouette to Defensor, and I think that really works. Longer cannons on his back here would have been nice though...
Toy vs. Cartoon accuracy - this version's definitely Toy accurate with the grey chest piece for Bruticus, and I'm tempted to pick up the announced "running change" variant with the Cartoon accurate brown chest piece, as photos of that look pretty sweet, and hopefully his knees are a little tighter.
