I don't think I've seen that barricade art before. Interesting.

 

He looks ready to fight Unicron.
EDIT: PowerMaster Optimus, by Josh Nizzi.

 

This needs to be made in toy form. Yes, Haslab is cool. If this guys comes out in ROTB 2 Id be so floored!

 

This was designed by Josh Nizzi, wasn't it? I could tell by the artwork of that fourth image.

 

Found this today, anyone has better resoultion or know who made it? Looks cool (i've no idea where this is from)

 

Even if it's fan art I want an SS figure of this guy.

 

I have never been able to tell if this is official concept art or not. I’d really like it to be official though. Ive always felt like the Dinobots were sorely in need of an ankylosaurus member. I think I’ve seen the name Slam used for fan made versions of the idea. Works for me.

 

I've got higher res images but not found a source

 

Nice. Never seen in better quality.

 

Some more Concept art for the Bumblebee Movie before it was turned into a reboot - https://www.artstation.com/artwork/Qn1ZVr

 

Cool

 

These are interesting! That one where he’s holding the girl is hilariously out of scale.

 

I see his rivalry with Barricade extends to who wears them glasses better

 

That one Bulldog concept piece but with the correct head from the other cropped concept image:



And just for fun, png versions:

 

So I know the HOK codes for paint are "House of Kolor" but what is the blue metallic labeled STG 04?

 

Cool find! There I especially like this concept

Personally more appealing than Evac.
I hope to see content like this sketch for every character if a movie art book is ever published.
