Big Time Rush is a TV series that aired on Nickelodeon from November 28, 2009 to July 25, 2013 for four seasons.

Guest Characters

(Note: Even on SpongeBob SquarePants, Patchy the Pirate is almost always portrayed in live action Patchy is most often shown in “kids show host” styled framing segments of SpongeBob episodes, but he has also been involved directly in plots.

“Big Time Halloween” is a non-canon episode that takes place in a world where the band are all horror movie monsters. During an attempt to change Carlos (now Franken-Carlos) into a normal human, he is briefly turned into Brobee as a sight gag.

The cast of Yo Gabba Gabba also appears in ”Big Time Cameo” but it’s in the context of a taping of the real life kids show rather than as part of an in-universe Yo Gabba Gabba crossover.)

Outgoing Crossovers

(Note: Big Time Rush is simultaneously a real life band and fictional characters who go by the same first names. I will assume that crossovers that happen during the run of their show while they are “in character” are proper crossovers, but it could be argued that these are celebrity cameos of the “real life” Big Time Rush. Complicating this further is that there is an episode called “Big Time Cameo” about how the boys are tired of filming cameos for other shows and includes actor Lucas Cruikshank from Marvin Marvin as himself.

“Big Time Marvin” is a double-length episode and I have seen it listed in some places as episodes nineteen and twenty.)
