How dumb are you all? Really? She has been a vampire since before she knew Simon (Ice King) and even longer before meeting Ash (Weenis)
Most likely she was turned by her father at age 7 (Yes that is the age she was back then) then her father left/got sent to the night-o-sphere some time after.
She ages at a rate of about 1 year in appearance every 100 years. That is why she was turned into a vampire at 7 only to look about 18 years old 1,000 years later when she meets Finn.
The fact that I needed to say this basic knowledge is pathetic.
Side note: I bet you are all too dumb to know that Ricardio (Ice King's heart) was the cause of Jake Jr. having that birth defect face.
Three things about that:
One, I didn't see bite marks on little Marcy in the flashbacks. Meaning she wasn't a vampire maybe?
Two, I don't think her dad is a vampire, but a demon. Maybe her mom is a vampire? Marcline <sp?> said a few times she was half demon. But then why would altrnate world Marcline look like an old woman there if the same amount of time passed?
Three, no need to be rude, dude.
