Jedi Mind Trick: Darth Veneficus attempts to force persuade his way out of trouble:
Professor Snape: As for you, Mr. Potter... Fired curse or no, your actions were a disgrace to the house of Slytherin, and you will serve a detention with me on Saturday, cleaning cauldrons and rethinking how you should have handled the situation...
Training from Hell: Harry/Veneficus has been training in the ways of the Sith since he was four years old.
Unknown Rival: Darth Veneficus does not acknowledge Voldemort as a true threat for he is clearly no match to the power of the Sith.
Villainous Rescue: Darth Millennial rescues Harry Potter from the Dursleys. Later Harry/Darth Veneficus and Draco do this for Hermione because Veneficus can see her potential to be a useful Unwitting Pawn.
Xanatos Gambit: Darth Millennial has several plots running, all of which, no matter the outcome, will advance the cause of the Sith.
