Air Krang

The sixth season of NBC's 30 Rock contained at least two references to Krang.

Blue Monday: Blue Diamond

Blue Diamond  redux. 

 Here he is back in his heyday, punching the hell out of some bricks.  Back then you could get loads of bricks for close to nuthin'.

Air Megatron

LeTron James

Blue Monday: Blue Beetle

DC Comics' Blue Beetle

Air Mumm Ra

Ancient Spirits of IN YOUR FACE! 

Blue Monday: Blue Devil

DC Comics' Blue Devil and his Trident of Lucifer.  Which, I can only assume is borrowed or maybe just on-loan from Lucifer and at some point, the ol' boy will want his fork back.

Air Cobra Commander

In the tradition of Air Skeletor (see below) from days past, I bring you Cobra Commander.  

In your facccce!
