Another OC made under the same concept as this one Combining aspects of two separate characters into one 'child'
The Kerrobenoff was an attempt by Queen Jaydes to give the Underchomp a bit of company and something to 'trade shifts' with so to speak, by using part of its essence to crossbreed a new creature with another ferocious but tameable hound. In the end, she saw a far-off clockwork planet known as Cradle that housed a large, nearly mythical beast known as the Snarbolax, and managed to obtain a few quills from it. The end result was... too successful.
Yes, it was a stable creature. A powerful one as well. Able to trap the very shadows around it in its pelt as a form of armor, dig through the dirt, launch its quills at foes, and breathe any assortment of flame, ice and noxious fumes. It was essentially uncontrollable. To avoid doing too much damage to the Underwhere, she had to send it far, far away.
Which is exactly what Kerri wanted.
What she'd kept hidden was that she wasn't just a combined package of the two hounds, she was smart enough to play a role. And so, with her freedom to roam as she saw fit, she let her true personality shine as a more placid, but still mischievous slacker, content to simply roam about, not causing much harm unless provoked save for the odd little prank involving teasing people with elusive glances at her.
When Jaydes found out about it, she could only really applaud the hound and allowed her to remain out and about provided she doesn't cause too much havoc.
Kerri, despite having three brains, only really has one mind, with each head acting more like a very extensive facial muscle than the entire face, so to speak. Each one reflects certain moods better than others, with the blue one being prone to happiness and sadness, the yellow one more towards neutral or contentedness, and the red one being enraged or terrified. Her eye, while functional, doesn't have a good range of vision both in color range and generally being unable to see anything above her, and as a result she relies more strictly on sound and smell like most other dogs.
