Yahshi was contacted by Aang to find rebel benders that could serve as potential allies against the Fire Nation. He succeeded and found four unique benders: Analay, a shadowbender who utilized shadows as her main weapon; Hiroshi, an earthbender who was proficient in tunneling and was capable of creating a rock dragon; Visola, a waterbender from the Northern Water Tribe who created weapons to augment her bending; and Riley, a warrior who had mastered the art of bending cookie dough. He introduced these benders to Team Avatar, but before they could be recruited, the benders left to start their own team.[1]
He was accompanied by an unnamed, horned, mole-like creature.
Yahshi is a fanmade character entered in the 2006 Nick Magazine contest where readers sent in their own created characters to be featured in the comic "New Recruits".[2]
