Ecto-Morphicons

The  insect, exoskeleton like zords.

How they worked..
The Titans were both zord like machines- -filled with Ivan's Ooze. Then they got brought to life with his lightning. Because they were filled with ooze, it was part Ivan already, so Hornitor got to be possesed, and morphed easily into Ivan-Hornitor. Increasing in size, strength, and mobility.
