So I like next gen characters and I like Adventure Time so I thought of some for adventure time and came up with a plot or 2 . So the plot idea I have is after one of Bubblegum inventions that was made to help people remember things goes haywire and hits Marceline she starts remembering something she forgot about due to a spell. Many many years ago (due to her being like over 1000 years old)when she was still wondering the Ooo she had a son(dad's not around don't need to bring him up really) And due to her life being stressful (due to lots of stuff) a wizard says he can take her stress away with a magic spell and all she has to do is sign a contract. She ends up agreeing only to realize it was a trick and the wizard vanished along with her son and her memories of him are locked away until present day. Now she wants to find him since he should still be alive due to him being like her. So the RP could be her and Finn and Jack or just her and PB going on a adventure to find him
