One (TPOT)

She's One from TPOT. And there's still not much we know about her and her origins yet. She recently broke out the moon Four trapped her in for decades. And it's hard to know what her true motive is. After she broke out the moon, She started spying on the other contestants and she had been making deals with them behind-the-scenes without Two or Four knowing. Once they signed her contract, They would either disappear from existence completely or get sent to another dimension. She has been manipulating the contestants for a better life and luxury only so she could have more power. Currently, In TPOT 19, One has both Four and Two's power's. However, It's still not confirmed yet why she wants their powers and what will she do with them next. But she seems to have a personal vendetta against Four and Two (Probably Three too.)
