The Nether Vault: Di Vinci Claus is coming to town (12/19)

Pit and Pendulum are twins who first appeared in the Nevervserse working for Black Cat, before switching sides and joining up with Raven against there former boss. They were experimented on as Children making them both faster then regular humans also making Adrien stronger and Andrew smarter. Durring the end battle against Black Cat, Raven granted the two of them Immortality so that they might survive the battle and just never took it away from them, hince how they have lived and remained young in the Future Time Line.    

Rodrick was Jon's Closest friend while Jon was alive and like it had with Lenore, that made him a target.

Madeline is the Sister of Roderick and one time girl friend of Jon, in her late teens the Doc's discovered she had a blood disorder that would very slowly kill her over the years. She wond up spending months in the hospital for it over the years and during one the visits she came very close to dieing and a shadow appeared before her and offered her power to live if she did what he ask and she agreed. The power turned her into a Phantom (a living Reaper) and it made her seem as if she was dead, she was placed in the family's crypt and she went about her mission which was to torment her brother and cause chaos while remaining unseen. The torment she wrought Drove Roderick mad and over time the madness allowed for him to be Possessed. (ok now we will jump ahead in time) after the events of the War against Black Cat, who was the Shadow that gave her power, she disappears for years only appearing once during on of the adventures in Modern Time line from which at the end she gives up the Phantom Powers and lives a few more decades before dieing and becoming a Reaper herself taking on the Name Echo because her Totem was that of a Bat.
