Trinity Jackie petrova/pierce/Mikealson - she's is always about survival and protecting family it's an instinct for her. She's stubborn and sarcastic but when you know her well she's caring and protective. She's badass like her mom and noble like her father that she isn't aware of. She gets a lot of attention but she tries to ignore it and keep going with her own personal life. She has few friends because most sue of old age and she's still going. When she turns fully Katherine tells her to go off on her own but keep secretly in touch. She gives off the vibe of protective, bitchy and scary. She's a ripper but sort of knows hot to control it more then Stefan would ever. She doesn't often compel people unless necessary or sometimes for fun and games. She's got motive and can easily slip through the cracks and get away with murder.

Katerina/Katherine petrova/pierce - you know most about her she's all about survival and keeping to herself. The only one she cares for other than herself is trinity her miracle baby. That and partly Elijah, she likes to play games and gets away with feeding off people. She taught trinity how to control her blood lust and ripper side. She's only caring towards trinity yet hides it most the time.

Elijah Mikealson- noble man he is most the time and always keeps his end of the deal (except once or twice when it comes to family. He's unaware of trinitys existence for most of her life. He's all about family and loves or loved Katherine when he first met her. He's not easily set off and has good control of his temper.

Gabriella hale - the first girl trinity ever turns only because she was dying and didn't make the it causing her to turn. She's always by trinitys side and helps the young/older hybrid with everything. She's very sweet, kind and caring for others. She knows a lot from trinity and has only met Katherine once or twice before. She doesn't know much about the Mikealson family and doesn't care to. She's big on friends and family but sad to leave her family behind.

Antonio Selveto (sel-vet-o) - smart, kind, sarcastic man. First love of trinity's life until he dies in 1876 from an illness. He knew trinity secret and died keeping the secret with him. He's all about protecting and promises but trinity didn't/wouldn't or couldn't turn him. He was 20 years old when he died in the hospital with trinity by his side. He didn't have much family except for trinity and Gabriella.

The rest of the Mikealson family you know about if you've watched all the series. I might mix twilight or supernatural into this as well so be prepared for that too.
