Tweak Family consist of Mrs. Tweak, Richard Tweak, and Mrs. Tweak and Richard Tweaks son, Tweek Tweak. Richard talks calmly which is completely opposite of jittery Tweek. He often gets lost in his own little world where he repeats cliché metaphors about how good something is. When he does this, he speaks in a somber tone of voice, accompanied by calm music.They supply their son with coffee (mixed with grounded meth), unaware it is the cause of Tweek's physical and mental problems, they instead blame it on his attention deficit disorder.Tweek is rarely seen smiling or expressing positive emotions, being almost constantly on the verge of outright panic. He is usually seen gritting his teeth or generally flipping out. Sometimes he may seem slightly calmer with less twitches and spasms when around his boyfriend Craig Tucker. He also appears to be easily manipulated, making him a frequent pawn plots Tweek does not fare well under stress, often experiencing feelings of extreme pressure.

PHIGHTING!!! consist of, Sword, Rocket, Slingshot, Boombox, Boomball, Banhammer, Medkit, Subspace, Biograft, Hyperlaser, Katana, Skateboard, Scythe, Shuriken, and Vinestaff. All Phighters possess some form of horns, except in cases where they are removed, such as?Hyperlaser. Phighters sleep in netted beds as to not disturb their horns. Phighters sometimes engage in horn fights. Phighter horns are bone, and can be styled similarly to nails (e.g. painting them,?Rocket?carving his horns to look like?Zuka's, Zuka dying his horns.) Carving horns does require maintenance - it is not a permanent alteration. Younger Phighters can regrow their horns quickly, whereas older Phighters will not at all. If the entirety of one’s horns is removed, they will die. Phighters do not excrete waste other than sweat. Phighters can get sick, they are organic beings and need to be cared for/take care of themselves. The average lifespan of Phighters is similar to the lifespan of humans.
