Krang. One of my favorite villains of all time.
For those of you who don't know, he was a major villain on the original TMNT cartoon.
In the original comics there is a race of beings very similar to Krang here called the Utroms. Krangs design was inspired by the Utroms, but thats about it.
Krang is a Warlord from Dimension X who was stripped of his body and confined to this brain like form.
When not in this little tripod mech, he is in the belly of his powerful exo-suit. which i did not want to draw. He lives in a giant sphere like fortress called the Technodrome, which he stole and was therefore banished to earth.
I wanted to draw him without his exo-suit to focus more on the character.
cheers.
