Four Chan is somewhere between a hacker, detective, and a super-scientist. He has a stunning intuition and technical know-how, and functions as a direct rival to Screentime. He always seems to be one step ahead of the New Warriors, able to locate their secret bases and predict their next move. In a fight against Screentime, after showing his total power over him, he gives a speech "You think the internet is your ally? You merely adopted the internet. I was born into it. Molded by it. I didn't leave my parent's basement until I was already a man, by then there was nothing but normalfags."
In an attempt to remedy an internal conflict he climbs into device of his own construction that can "double ones power". The device is destroyed, but he evolves and becomes 8 Chan (Everyone calls him eight chan, but he insists on being called infinity chan). He becomes even more difficult for the New Warriors to deal with. He assembles remote clues to discover their plans, immediately figures out their secret identities and where they live (which he spreads on the internet), and develops even more overwhelmingly powerful technology. However at the same time he is more insane, more radical, and less filtered. He is consumed by his 8 Chan identity. He takes a very Joker-esque "Everyone can become like me if given the right push" sort of attitude.
Some Gary Stu bullshit (in the words of 8 Chan) brings Screentime up to 8 Chan's level, and so 8 Chan and his crew determines that he needs to evolve again. He builds a machine that will take him into his final form, Infinity Next. However he is pushed to hard and when he tries to ascend he instead crashes. The process leaves him scared and deformed, and even more insane. With him now vulnerable, the New Warriors take advantage of his weakened state and are able to defeat him. A snowflake shuriken in his forehead finishes him off, or so we think. In reality he shatters into innumerable different villains, all similar, all psychically linked, and yet all filled with some form of hate, distrust, or general dislike for each other. Should they unite into Infinity Next they would certainly become an unstoppable force, but until then they are more a thorn in the side of the New Worriers, occasionally dangerous (or very dangerous when allied with other groups) but not the persistent threat that he was.
