John Paul "J.P." Mercer is the tritagonist of the Cartoon Network series Craig of the Creek. He is a young boy who is most often seen near the creek with his best friends Kelsey and Craig. His first appearance was in the Pilot.
J.P. is tall compared to most characters in the series. He has light skin, a large head with proportionally smaller cheeks, black eyes and eyebrows, and red hair.
J.P. wears a long-sleeve orange and white striped V-neck, black shoes, and tan pants with a tear on his right knee.
J.P. is not the brightest when it comes to thinking things through. He'll eat random food off of the forest floor and not listen to instructions.
Despite his weak intellect, he is quite a caring person and loyal friend, especially when his friends are in need of his assistance.
Even though he's older than Craig, and Kelsey he's pretty irresponsible. And it seems in episodes like "Dinner at the Creek" and "The Shortcut" it seems that J.P. is easy to manipulate due to his low intelligence.
- His family has a cat named Goo.
- He has a rash on his torso in the Pilot.
- His full name is John Paul, as revealed in the episode "You're It" when he states he is building a robot clone named Johnbot Paulthousand.
- J.P. said he has a tetanus shot.
- He is the oldest among his known friends.
- "Sunday Clothes" reveals that J.P. is in middle school.
- He stated that he doesn't know how to breathe out his nose.
- Despite his attraction to dangerous stunts, he is only known to have broken a bone once (his hand, as stated in "Jextra Perrestrial").
- He has many similarities to Ed from Ed, Edd n Eddy. They both are not too bright, wear a red and white striped shirt, they have two best friends, they both have a sister (J.P. has an older sister while Ed has a younger sister) and they both run in a similar fashion. He also somewhat resembles Rodney from Total Drama Pahkitew Island.
- J.P. finds some non-vulgar sayings offensive. For example, in "Kelsey the Author", he tells Craig to watch his language when he exclaims "Forget the world!"
- The episode "Jextra Perrestrial" suggests that J.P. may have ADHD or autism, as his sister Laura states that, "his brain works differently".
- He was friends with a crayfish named Big Pinchy when he was a kid in the episode of the same name.
- In "Into the Overpast" he reveals that he enjoys pineapple on pizza.
