Transformers Animated - Mortilus

Mortilus, the Death-Bringer, the death god member of the Guiding Hand.  Like with the Fallen and the Thirteen Original Primes, Mortilus brought about the downfall of the Guiding Hand when he urged for the group and their Cybertronian children to become a fist against the universe.  This led to the deaths of most of the Guiding Hand.  Mortilus' own death serves as an allegorical explanation for why Cybertronian sparks are seemingly immortal.

The character was introduced in IDW's comics, and his story is told in a way that is intentionally ambiguous on whether or not it's true.  This is just what I figure he might look like if he was in the Animated Universe like what I did with Primus.  I'll eventually do the other members of the Guiding Hand, the 13 Primes, and Unicron himself.
