- "And remember to excersize everyday! It'll help a lot on the field!"
- ―Mr. Hill, 2011 and 2012
Mr. Carlos Hill is a minor character in Sibling Rivalries anf Sibling Rivalries: Salvador Real's Adventures, and a main character in Sibling Rivalries: Vancouver Stories. He is the gym teacher at Wisconsin Elementary School in 2014, the coach of Salvador Real's soccer team in 2012, and the coach of Jason Parker's football team in 2011.
- Originally his first name was Scott, which was a reference to Scott Hill, the voice actor of Johnny Klebitz in the Grand Theft Auto series.
- Mr. Hill originally held the position as the first human character in the GTA Nerd Comic Universe to speak, until 2016 when Tristian Duran took that place (originally Sibling Rivalries: Vancouver Stories, set in 2011, was the first chronological GTA Nerd Comic Universe story to feature humans, until Turner's Second Chance came out, which began with a flashback to 2005).
- Mr. Hill is a tribute to one of GTA Nerd's gym teachers in elementary school, whose name is Mr. Becker. Mr. Hill, like the aforementioned teacher, is very nice.
- Mr. Hill was originally going to be a mean gym teacher who yells a lot, but GTA Nerd wanted him to be nice.
- He is Packie's favorite teacher at school, despite Packie hating excersizing ("Dodgeball Mishap").
- His only lines in SR: SRA would be reused in SR: VS.
- He is the coach of the Vancouver Vultures in 2011, but it is possible he was fired or quit, as he became Salvador's coach on an unnamed soccer team in 2012, then the gym teacher for Wisconsin Elementary School since 2014. This leaves the Vultures and the unnamed soccer team coachless as of 2014, until Esteven Caballero took over as coach as revealed in Turner's Second Chance.
