Velco

Velma x Coco Diablo is the femslash ship between Velma Dinkley and Coco Diablo from the Scooby-Doo fandom.

Canon
Velma and Coco Diablo first meet when the gang exposes her as a villain. Coco was undercover as a costume designer, when she is in fact a villain. When Velma goes to meet her alongside the Gang, she is instantly mesmerized by Coco, and quickly develops a crush on her. Although Coco later is imprisoned for a year, Velma's friends instantly become aware of her feelings for Coco. When Daphne suggests that she suspects Coco was behind the Count Nefario attack at the Coolsville Halloween Fest, she says they should pay her a visit. Velma instantly shows her excitement by squealing "I love that idea!" But as soon as she gets a knowing look from all her friends, she tries to save the situation by pretending that she is not that excited. However, as soon as she sees Coco for the first time since she was arrested, Velma blushes and utters a "jinkies," completely in love with Coco.

When the Gang accuses her of being behind the mystery attack, Coco denies this. And Velma is quick to suggest the idea of Coco joining the Gang to help solve the mystery, since she thinks Coco is really smart. And Velma finally confesses her feelings for Coco to Daphne, after denying them at first. When she shows how excited she is to have Coco join them, Daphne jokingly says that she didn't know convicted felons were Velma's type. Velma tries to dismiss Daphne's joke by saying she has no time for love since she's focused on work, but quickly drops her facade and pleads with Daphne to give her advice on what to do and say since she's "crushing big time" on Coco, to which Daphne replies by advising Velma to just be herself.

After this confession, Daphne is invested in her friend's crush and helps her get the confidence to talk to Coco. Velma is very awkward at first, but as soon as the two start talking, she really gets into it, but Daphne cuts her abruptly before she embarasses herself, telling Velma that she's not really doing well. When Velma comes back to her conversation with Coco, Coco calls her "the cute one", which has Velma swooning.

After the Gang saves Coco from her kidnapper, it's time to say goodbye and she and Velma have a private conversation. Velma says that she likes to think that in different circumstances, they'd really get along. Coco seems very interested by Velma's remarks, but Velma thinks she messed it up again, "saying the wrong thing again." However, Coco tells her that she agrees with her, whispering to Velma that she is the first person she likes "other than herself." This makes Velma swoon again as she blushes and says "jinkies!"
