Project producer Tony Cervone confirmed the fan’s guesses: he stated that Velma was always a lesbian in the 2010 animated series Scooby-Doo! Mystery Incorporated, which restarted the classic comic strip in 1969. He emphasized that the character was created as homosexual:

‘I said this before and will say it again: Velma is not bisexual – she is a lesbian. We have outlined our position on this issue as clearly as it was possible ten years ago. Most fans understood this. For those who do not understand, I advise you to review the series: everything is obvious there. It’s not even news,’ – he wrote on Instagram.

Velma’s homosexuality has been a topic of discussion since the very first appearance of this character in the original comics, but it has never been emphasized: in the 2010 series, on the contrary, they decided to emphasize it.
