One is the main antagonist of TPOT. She is the first real villain in BFDI. She has stalked the contestants, made deals with said contestants, and caused a storm, which either killed or kidnapped Leafy. She isn't as strong as Two, despite also being algebralien.
Anyways, I love them. They are a very silly character. I wonder if they want revenge over Two, want to steal Two's power, or both!
While One wasn’t an important character before TPOT, she has appeared in X Finds Out His Value (XFOHV) and BFB, though since they are unimportant, I won't cover them. Then again, I didn't watch BFB post-split.
In TPOT 9, One was introduced to us when the Moon cracked at the post-credit scene. Because of that, a lot of people were speculating about her appearance. They thought another split would happen, like the BFB split, One would cohost, or One would become an antagonist. After her first appearance in TPOT, I was intrigued by her, and looked at a lot of speculation. My speculation at the time was that she would be an antagonist turned-cohost, but now this seems unlikely with TPOT 12 and 13.
After that, in episodes 10 and 11, they appeared many times as a cameo, only being noticed if you were looking for them. Notably, she cameoed in the contestant’s nightmares, which shouldn't be possible, hinting at her possible omnipresence, and shows that is stalked them to the extent of peering into the object’s minds. In TPOT 11, another algebralien was introduced in the post-credit scene, which seemed to be Three, who was trapped in the EXIT. This makes me wonder why they were sealed.
She starts to become very important in TPOT 12, which is when she makes her first no-cameo appearance since TPOT 9. She might have stolen some contestant’s limbs, and with those limbs, she coerced them into signing a contract by making them sign it to get them back. She asks why a contestant wouldn’t help out an old friend of Two’s, which could be herself, or Three. This whole contract, as well as her calling Two an old friend of hers thing led me to believe she wants revenge, possibly for being sealed in the moon, and wants to ruin the contest.
In TPOT 13, One, after making some contestants sign the contract, gets to the “main course:” Creating a major storm which causes something to happen to Leafy, whether intentionally or not. During that time, she was living a comfortable life with Firey on her. Their cabins that were built were also damaged, and Firey is looking for Leafy, but does not make another appearance until the post-credit scene.The storm also swept away the EXITors who didn’t rejoin, as well as some other contestants. The challenge ended up being related to the storm they caused.
Her most notable appearance is when she pressures Basketball into signing her contract, by promising to end the storm and to bring Robot Flower back by using a timer. (she lied to Basketball about the storm, which helps prove my theory that she stole some of the contestant’s body parts) Back in TPOT 7, Robot Flower overwrote herself with Season 1 Flower, which made her very violent and caused her to fight in the latest episode and be weakened to be able to have her real self recovered. Notably, One says to Basketball that she has power, but not enough, and then the screen turns towards Two, hinting that she is weaker than them. A lot of people think that she wants Two’s power, and is making the contestants give her their power. If she wants vengeance, then it would make sense that she wants Two’s powers because she could get revenge on Two, without them being too powerless to stop her.
