Before becoming a Tefender Morgana had been subjected to rigorous abuse from transformation gadgets, magics, curses, and harp seals then when she was found by the being who made the Tefenders she was freed from her hellish morphing torture. When she was picked up she seemed to be physically and mentally a 16 year old girl, but with a few odd quirks like she could hold her breath for a really long time. Most of the quirks ended up not mattering to a Tefender who was basically immortal as they went through the multiverse doing their job.
Morgana couldn't remember her name, or even what she was when she began. She just knew that anyone abusing those transformation things against the defenseless were monsters that deserved the worst. Any time she saw anyone breaking the rules she gave them a punishment worse than death. Was it fair or just? Morgana didn't care, she was sending a message "Abuse the powers of transformation and you will not be safe."
