I hate how some people make him some fragile pathetic twink. He is an elite guard and an intelligence officer. I think people forget that there’s a /reason/ Shockwave tried to kill off Blurr.
It's funny when Lockdown captured him for "killing" Megatron, he tried to pin the blame on Starscream. But, last time I checked, Starscream only blew up his right arm, while Optimus literally kicked him out of the ship, while it was entering Earth's atmosphere.
