Here's G1 Sunstreaker with all kinds of expressions(with his brother, Sideswipe, annoying him as well), ranging from surprised anger to mild annoyance.

Personally my favourite one is the one where he yells "You did WHAT?!"... xD

Also, I'm planning on making a comic about what might happen if the Autobots(and Decepticons) turned into dragons. I have a few hilarious ideas already x'DDD

For example;

Prowl glitches(faints)
Sunstreaker shrieks like a femme
Ironhide freaks out because he can't find his cannons anywhere
Bumblebee almost freaks out because he can suddenly talk again
Optimus Prime faceplants into the floor after attempting at standing on his hind legs and Echo falls on the floor laughing like a retarded hyena (x'D)

Starscream gets tangled into a pile of wires and cables because of his huge wings
Barricade almost freaks out
Blackout literally blacks out
Frenzy freaks out and goes hyper

The rest is a surprise~ >w>

Also, tell me wich of these expressions is your favourite! I'd like to hear that!

Sunstreaker, Sideswipe, and all mentioned characters (except Echo) belong to Hasbro
Echo belongs to me
