'Cause every other DP fan out there has them, so sue me. Some second-generation DP OC for a fic that's been percolating for a while:
Adam Fenton: Son of Sam and Danny, age 16. One of a set of fraternal twins, Adam inherited his father's snow-white hair and his mother's violet eyes. He's much calmer and quieter than his more impulsive twin sister. His ghost powers are latent at best, but Adam does possess a highly sensitive ghost sense. Considering his background, Adam is something of an odd one in his family, as his preference is for talking with possible opponents instead of searching for the nearest blaster. His weapon of choice is a modified specter deflector.
Lily Fenton: Daughter of Sam and Danny, age 16. Lily takes after her mother's stubbornness and her father's impulsiveness, much to the dismay of both. She's outspoken and eager to uphold what she believes is right, even if she's not as sure of herself as she likes everyone to think. Lily inherited a broader range of ghost powers from her father, including flight, transformation, and ectoenergy manipulation. Her powers are still weak and developing, however, but with time she could prove as powerful as her father. Her main weakness is her glaring lack of ghost sense. Lily relies often on her brother to sense trouble coming and to bail her out when it hits.
Ida Baxter: Daughter of Sam and Dash and youngest of the Fenton/Manson/Baxter siblings at age 13. Ida is named after her grandmother and seems to be following in her daredevil ways. While Lily may act the bold one and Adam the fearless one, it's their little sister that truly lives without fear. She's an eager student of everything her parents have to teach, from Sam's lessons on morality, Danny's lessons on responsibility, and Dash's lessons on maximum damage with minimal collateral damage. She has a puppy-crush on Jenny Gray. Jack Fenton's unofficial favorite grandchild.
Micheal "Rasputin" Masters: Clone of Vlad Masters, physical age 17, literal age 5. Originally created as part of an experiment in immortality through memory recordings and cloning, something went wrong and the clone was released from the pod too early. After a few misunderstandings, Vlad accepted the human clone as a reasonable substitute for a proper heir and trained him as a successor. Rasputin interpreted the relationship as a filial one, even if one-sided, and refers to Vlad as "father." Existing in this timeline as an analog to Dark Danny Phantom, Rasputin became obsessed in reaching what he saw as his full potential, up to and including overcoming his mostly human genetics to fully awaken what little ghost DNA was used in his creation. Manages to rip Vlad's ghost half from him and merge with it, creating a new ghost hybrid who refers to himself as Rasputin. ((note: his name needs work. something creepy but less cliche villain-ish)) A chance encounter leads to an obsession with the next Fenton generation, specifically with Adam and Lily.
Jenny Gray: Daughter of Valerie and Kwan, age 15. A quick date lead to an unexpected pregnancy for Valerie and it was a while before young Jenny got to know her father. Her relationship with her parents is somewhat strained, even though all parties involved are trying their best and truly do love one another. Jenny has a prickly personality, and is quick to defend herself with sarcastic comments. She works well enough with the Fenton children, preferring to use hand-to-hand combat over Fenton siblings more specialized approaches to ghost fighting. She finds Ida's little crush to be cute and occasionally flirts back, much to the other girl's delighted embarrassment.
