|This character exists primarily or exclusively within the Sonic X anime or comic continuity.|

Notably, he is the first character to appear in the series, as he is seen sleeping by a river with Froggy in the beginning of episode 1. His most notable appearance was during the Sonic Adventure adaption, where he played the same role as he did in the game. At the start of the series, he was apparently caught in the Chaos Control explosion that transported the main characters from their world to Earth. However, he did not make another appearance until a second Chaos Control event brought several locations from their world to Earth, though in one episode, he is seen fighting with Ella in a tournament in the Japanese version (the English dub has cut the entire fight between the two). It is unknown if Big somehow remained on his homeworld until the second event, or if he had been on Earth the entire time and nobody knew about his whereabouts.
