TPOT:One’s lab au

This is an au I came up with. Basically, one has both 2 and 4s powers and is keeping them both locked away. As for the contestants, they are contained in cells and treated like test subjects. You get to decide the rest! Also the characters/ subjects are: Blackhole( male), Fanny( female), Marker( male), Tree( male), Liy( female) Pen( male), Bottle( female), Tennisball( male), Golfball( female) Donut( male) Pencil( female), Winner( nonbinary), Price tag( nonbinary), Book( female), Grassy( male, also a child), and snowball(male) This takes place during episode 19 before the challenge was decided
