Spoiler warning: Beginning here are "spoiling" details that may relate to the story plot and/or contain plot surprises.
Clay Yanick Jones is a fairly minor character in Equidae and Stanford. He is the gym leader of Driftveil City and sometimes works as an INTERPOL officer whenever he's available.
He is easily distinguished when wearing his emerald-studded and gold-banded, white cowboy hat. He has curly, brownish hair that he rarely combs. He also wears brown baggy pants and vest as well as a teal tie (the innings of his pants match his tie) and maroon undershirt.
