Anastasia "Polaris Northstar" Blanche Leacroft the Sin of Gluttony
Anastasia Blanche-Leacroft preferring to go by her nickname Polaris, was raised single handedly by her hardworking mother Sonia Blanche, while her absentee father Herman Preston Leacroft; also known by his writer name "H.P Leacroft" abandoned the both of them before she was born and then passed away from illness before Anastasia would ever officially meet him, she would only really know her father through the books he wrote. It would be inaccurate to describe Herman Leacroft as a pokemon with issues, more like he was a shambling mound of issues in the approximate form of a Cat. He had various mental and social issues: chronically depressed, hypersensitive to criticism, prone to horrible nightmares and nervous breakdowns, along with many strong biases from growing up in the old noble house of Leacroft which had long been in a state of decline long before he was born and was already starting to fall apart, but still held onto their archaic belief in Blood Purity and Superior Breeding. Herman did what his family considered a major fopaux by marrying Sonia Blanche an author like him but was not born to a noble house, rather she was a self made business woman. She had given him a semblance of peace and sanity and the ability to start a new life, the two of them could have been happy together, but thanks to machinations of the Leacroft family Herman was separated from his wife and fell back into his old hateful biased mindset renouncing his love for Sonia and isolating himself in the family manor till he would eventually die of illness never knowing that he had a daughter.
Anastasia would eventually inherit the manuscripts of her father's horror stories; The tales of incomprehensible monsters and unknowable gods from beyond our own known reality, the nightmares that had horrified him and haunted his mind had become the dreams and passion of his estranged daughter. She was not only not scared of these creatures, but became enthusiastic about learning more about them. In many ways she is similar to Herman but also the opposite: They both lacked the ability to express themselves normally around other pokemon but where Herman had hatred and fear everything he didn't understand, Anastasia loves and accepts all things for their differences and uniqueness, especially things that other pokemon consider weird or creepy.
She got herself neck deep into learning all she could about the occult being a hyperfixation of hers trying to seek out beings like the ones in her father's books from beyond our reality in the spaces beyond space and imagination wanting to meet them and understand them despite being claimed to be incomprehensible. Unlike most Warlocks who have an exclusive contract with one powerful entity and then lose all their power should they break that contract, she is has become almost an eldritch entity herself capable of her own bizzare otherworldly powers, but is still limited by her physical body so she will act as a freelance warlock jumping between contracts between various Otherworldly patrons making deals with them in exchange for power and secret knowledge. Many of these deals can be considered dangerous but Polaris has become cunning when it comes to negotiating deals and she is more than willing to take risks because power and knowledge has become something of an obsessive addiction to her, earning her the title of the Sin of Gluttony.
She is also capable of eating vast amounts of food even though she no longer requires food to function as one of her eldritch abilities. She can consume almost anything: Matter, Energy, Light, etc...but it serves a different purpose than just giving her the energy to sustain herself, she can also transport the contents she devours to patrons who need it for sustenance as part of their deal. She has worked for many of the Ultrabeasts feeling Light to Necrozma, various nonspecific matter to Guzzlord, Electricity to Xurkitree, Vital Energy to Buzzswole, and Mental Energy to the swarm of Nihilego. The downside to this deal is that ironically Polaris no longer possesses the capability to taste anything so she can't enjoy food anymore.
Polaris joined the Seven Deadly Sins because she thinks the other members of the team are fascinating and leads her to interesting places. Her main weapon is a two bladed rapier called Brainbiter which appears to be made out of clear glass, but is somehow flexible. This blade can stretch and bend like a tentacle under the control of the wielder maneuvering around weapons and armor to pierce or cut the enemy. A single cut from this blade is enough for it to inject a Neurotoxin that within mere moments of being introduced to one’s body is able to give them vivid hallucinations. She also has a power called Uncertainty, allowing her to be where she isn't when not being observed, so the moment you take your eyes off her she could just be somewhere else entirely but only places where she has at least seen before making her very good at escaping places.
