Marceline's mom should appear in the miniseries *fingers crossed*
This is only a fan-made prediction (made by yours truly) but if you think about it it wouldn't seem too asinine to consider it as a possibility. In an article, it says
Cartoon Network described the new multi-part series as new adventure where Jake and Finn confront a brand-new threat, while Princess Bubblegum releases a ghost from Marceline’s past.

It doesn't state who this "ghost" may be, which could be anyone, but I would make a wager that it's Marceline's mother. After all, the series has subtly touched upon her existence in the show's canon during trivial moments, yet they may be quietly building up to her first true physical appearance on the show. These moments do come up as listed on this Wiki site:

Granted, there's still not much to go on in order to support my prediction, but whoever from Marceline's past comes back to haunt her in the presence must carry enough significance for viewers to tune into the miniseries, since it's going to be a major event in the show's run.
If anything, I would also wager that the previous vampire monarch that was dethroned by Marceline in the past would be another likely choice to come back as a ghost.
