She is me as a lioness, basically.

Rejected at birth, she was raised by another pride, a group of 7 female lionesses, 2 of which were her main guardians, one being an older female who was her adopted 'grandmother' and another being her 'mother' figure.
Nguvu was a bit of a hyper cub, getting into trouble in ways that were not troublesome, but frustrating to other animals. She was known to bit and shred apart many plants, trees, ant hills and hives just for the fun of it.
She was also very, very strong. This is how her name came to be, by her adopted mother rightly.

She grew into an awkward teenage lioness, not knowing how to show her real self and putting on a cold act for most of her pride, or even other animals who came to visit of passed by, though deep down, she was a deep pool of mixed information that only wanted to be loved, protected, and safe.

As she became a mature lioness, she has become an indirect leader for her pride, a source of information and solace to all, someone to be honest but also be as ind as possible, and also to be one of the strongest females to walk the savannah.
Her speed is not a strong point, but she can take down any prey 2 times larger than her without much of a struggle. Her intolerance for pain is her down-point, but she has the will of the strongest gods out there.
