BIO:  Catilla is patient and vigilant.  He appreciates the importance of his job, so he has no problem squatting down silently in his position and just observing Decepticon activity for however long is needed.  Catilla knows that he'll eventually get to his prey, and he prefers to be fully prepared for when that happens.  After stalking his targets, he takes great pleasure in their eventual destruction.  Previous to the war, Carnivac and Catilla operated as part of an investigative law enforcement team.

WEAPONS/ABILITIES:  Subject's outer pretender shell helmet is equipped with a full range of scanners, infrared sensors, radar and various tracking systems.  the shell's armor boosts his speed and agility, and Subject has a top running speed of 150 miles per hour in this mode.  Both his shell and alternate mode have durabyilium steel claws and fangs that can tear through armor.  Subject is armed with an air concussion cannon in robot mode.  Tail can wrap around and crush most opponents.

WEAKNESSES:  If circumstances force Catilla to strike when he's not ready, he can feel overwhelmed and opt to retreat.

Bibliography of significant appearances:
* I'm the first to admit I'm no expert when it comes to the UK Transformers series of the late 1980's.  But that's where I had to dig, to find *any* appearances of Catilla in Transformers mythology. Catilla made some cameo appearances in the "Time Wars" series (UK Transformers issue #199-205).  He also meets his demise in UK #239 trying to rescue is *comrade* Carnivac, from the "Mayhem Attack Squad" shown to the right.
