There is this person I have been following on twitter for a while. ( https://x.com/tikhondownichi )
They made a joke about Sebastian being part female angler that he would lay eggs and one accidentally hatched. Thus Gremlin/Prova was created. She is Seb's unwanted daughter that is trapped at the blacksite.
Unfortunately, Sebastian is a horrible father and I want to take her home so bad. So I drew this as some fan art and as an excuse to feed her cheddar cheese soup.
