With a big heart that's full of enthusiastic and optimistic energy in almost everything she could encounter or do within starfleet, Ensign D'Vana Tendi was an Orion whom served on the U.S.S. Cerritos. She notably on the lower decks of the vessel where much of the action focuses on the menial tasks rather than up front where the truly exciting jobs are.
Her friends as well as her job as a starfleet officer meant everything to her. Despite others showing little notice for her positive and kind nature, it very rarely if ever slowed or dampened her spirits or morale. Instead, she turned that into raw motivation to complete her tasks and work harder than ever to achieve the mission goals or beyond if possible. Her patience and long wick made her quick friends among beta shift; though she was at first to voice her actual feelings or concerns for some time.
She was exceptional as a scientist and a doctor, showing great promise to one day be a senior officer. However, ship's physician Dr. T'Ana felt concerned that she was too much of a pushover, and allowed her fellow crewmates to walk over her. Eventually though, Tendi, with the help of her friends and doctor, she was able to overcome her initial fears and prove to be a capable member of the crew in her own right.
One may never guess, but despite Tendi's warm nature, she was in fact an Orion, and like most of her race, fell to piracy. However, she was quick to turn from those ways, and actually shows a serious pet peeve towards species' stereotypes especially regarding Orions. She worked harder than ever simply to prove that she was not like others of her kind.
