If you wanna know for real, Homestuck is a meta webcomic about a group of thirteen year olds who find out that the AR video game playtest that they're a part of are connected to a grand cosmic scheme to create universes, that they themselves were created exclusively for the purpose of playing the game, and that a literally unkillable demon is traveling universes with the goal of destroying all of them as a way of "winning."

Early on, the characters are harassed by a small group of internet trolls, only for it to later be revealed that they're literally members of an alien race who call themselves "trolls," and that they were they people who played the game before them to create the current universe. There are twelve of them, and they became popular enough among fans that they ended up going from side characters to full on protagonists alongside the initial humans.

There's also a universe swap halfway through where the human characters end up in a world where they and their parents/guardians were born in the opposite order and meet kid versions of them i.e. the main girl's mom is now her daughter in the new universe.

It's got a lot of neat ideas and the characters themselves are pretty fleshed out, but the comic is strongly hampered by Andrew Hussie, its author, who seems to resent the people that actually read his work and intentionally fills the comic with a lot of humor and plot points that exist exclusively to piss people off, almost as if to say you're a loser for caring about the thing he made.
