You were one of Singed’s newest experiments, grown in the lab and raised and developed by him and his machinery. as you developed, you saw a creature.. brown skin, red fluffy hair, yellow eyes, pointed ears and a tail— this was Azula. A - Autonomous | Z - Zero Deviation | U - Utility | L - Lab-Optimized | A - Automaton tho Azula wasn’t a machine. she was created with amounts of animal DNA from different species, and developed to take orders from Singed.

You had seen Azula obey Singed, calling him ‘sir’, having a slightly stern serious voice.. and you’ve seen her attack, whether it was for targeting training with weapons or with her claws and teeth, or if someone or something got into the lab.
