Two

Two is an algebralien and is the host of the fifth season of BFDI, Battle for Dream Island: The Power of Two. Two was intended to first appear in the video "X Finds Out His Value" in 2008, but was cut and didn't appear as a sentient algebralien, though they did earlier in The Number Playground Chronicle!. Two made their first canonical appearance on BFDI in "The Escape from Four" as the episode's main antagonist. Ever since their debut, Two is known for having limitless power, making them one of the most powerful characters in the entire franchise, as they were given the most Yoylite power by the Algebraliens as revealed in Alone. They arrived on Earth while Four was out of control, and offered the contestants a chance to harness this limitless power, which captivated them and led to a shift to Two's game. He stole Four's contestants.
