After hundreds of millennia, Alucard, Seras Victoria and, the newest Vampire of the three, Sir Integra Fairbrook Windgates Hellsing wake up in a world that is no longer habited by humans but by ponies, pegasi and unicorns. Now chaos ensues when the Mane Six find them since Integra wants to rebuild her organisation, Seras now wants to blow up most thing with her Harkonnen and Alucard is being, well, Alucard.

Oh, and somehow, Alexander Anderson and his two students are alive.

Based on the Hellsing Abridged series and Hellsing Ultimate, but with my own flare.
Please don't sue me I own nothing.
