From my Transformers AU, I'm very proud of its design.
It's a awful necrotic beast that has sank into Seibertronian legends and tales intended to scare naughty younglings. They use their beaks to break through a Seibertronian's hard chest plates and then their fangs and their beak-tip are well designed for stripping away flesh and other innards to get to the 'spark'.
Notes: It has feet like an Ostrich. It's hands have the same ridged/rippled skin as Gecko feet. This helps it cling to walls/ceilings while it's legs and claw-limbs grasp a victim. This makes victim-rescue less likely and helps it eat away from potential threats ensuring a proper meal. This also makes it a superb climber and they can travel over almost any terrain. Just a single bite from one of these can cause something horrible. Something Cyclonus is gonna learn the hard way. Wanna know what it roughly sounds like?
