Craig Tucker is a member of the boys' fourth grade class. Craig's most distinguishing physical feature is his blue chullo hat topped with a yellow puffball. One of his traits is his compulsive tendency to flip people off, usually for no discernible reason. He leads the group known as Craig's Gang (aka Craig and those guys). He is one of the two children (along with Tweek Tweak) who are openly gay.

Relationship with Tweek

In "Tweek vs. Craig", the main boys, on account of a bet they had made, claim to Tweek and Craig that each had insulted the other, and convince them to fight. When it turns out neither of them knows how to fight, they have them trained for it. Craig is trained in Sumo wrestling by Cartman. After the fight, both boys are hospitalized, but the kids fool them into fighting again. It is possible, however, that this fight brought the two boys closer together, as they are seen together on very many occurrences in later episodes.

In later seasons, Tweek and Craig can be seen standing side by side in various episodes including "Ginger Kids", where they are trapped in a cage together, and in "The Wacky Molestation Adventure", where they are on the same side of the town.

In the episode "Tweek x Craig", the new female Asian students draw Yaoi pictures of Tweek and Craig in love, despite the two not being together. To stop the drawings, the two-stage a "breakup" in front of the school to stop the pictures, but Tweek goes too far in his role and makes Craig out to be a cheater by inventing a "Michael" that Craig cheated on for dramatic effect. This crushes the town's spirits, so the two reconcile in order to appease the town. The two are now in a genuine relationship.

In the Season Twenty-One episode, "Put It Down", Tweek stresses over the nuclear bomb threats made by North Korea. Craig suggests that he make cupcakes for them. Craig tries his best to make Tweek feel better. He gives him fidget spinners to fix his anxiety and gives him logical answers to his problem, which only makes things worse. But after hearing Heidi's speech about grieving, he comforts Tweek and talks with him about how he's feeling, helping him truly feel better.

Although their initial relationship appeared only to be in order to keep the town happy, following the events of "Tweek x Craig", the two have grown closer. In "Put It Down", Craig calls Tweek the affectionate pet names "babe" and "honey", even when no one is around, implying their relationship is now genuine. They are also often seen holding hands ("Put It Down", and "Splatty Tomato").
