Mongo was a Pokemon Jared caught at Level 23. Mongo is known for having one of the shortest life-spans in the entire Nuzlocke series, lasting from the end of Part 14 , to the middle of Part 15.
Mongo only took part in one match, which was against Brains & Brawn Frank & Sly. Despite fierce resistance against Teeckadee during her capture, Mongo was taken down by only two Psybeams from Mr Mime, failing to initiate any attack before she met her fate.
