I just have a lot of headcanons for this series, I really don't know why. Most of them will be character based, but I'm kinda lazy so I'm not going to sort them. But I will differentiate each character, so each character who isn't from the base four have a nickname:

Purple Haired Nick: Mr. Edgepants

Imposter Nick: C-36

Space Jail Jon: Stabby McStabberson

Some of these will be based off of the evidence in the episodes, but a lot of them will also be just add ons that help with their characters.

- Jon is actually illiterate, the joke in one of the episodes wasn't a joke. He can write, but he can't read

- Jon is the only one out of the whole group, excluding Nick, to have a driver's license. Don't ask me how he passed the driver's test when he literally can't read, but he did it anyways

- Jon met Nick two years before the events of the series, so when he's about 18

- Nick can actually hear the laugh track since only the people who are from the universe can't hear it

- The inter dimensional shape shifters can't replicate clothing, only the person's basic shape

- Ashlie isn't the one who makes changes to her house. She just goes to sleep and BAM. New potted plant

- Ashlies generally don't have romantic feelings for Nicks, this is why the replacement trick doesn't work on specifically her

- Uni can't cook for the life of himself

- Uni is a puggle, or a mix between a beagle and a pug. He refuses to admit to it, though

- A Duni does exist in the Middle of Nowhere. He's not a psycho and is a generally pleasant person to be around. Uni is also dating him, so here's to the ship

- Unfortunately, no one else from the D-Gang is there

- Mr. Edgepants sent serious alarms off in every Nick he met

- Mr. Edgepants used to have access to all sorts of classified data because he used be sort of an enforcer for the Council. This, of course, got taken away after he was sentenced

- C-36 hates his Jon

- C-36 felt genuinely hurt when the gang was distancing themselves for him because he was envious of their relationships with one another

- Stabby McStabberson doesn't talk to his neighbor. He thinks he's crazy

- Stabby McStabberson has escaped Space Jail so many times that all of the guards and employees there know his information by heart

Huh. Maybe I should make another chapter for THQ headcanons (I actually don't have any for Jonstoner, strangely enough. Mainly because I never finished it).
