Raul Chamgerlain is a world-renowned French fashion designer who looks surprisingly similar to Bobby Pancakes. The resemblance was strong enough to allow Bobby, after some minor plastic surgery, to impersonate him and gain access to high-society events in his place. This mostly consisted of replacing his ear which had been removed by Strahd von Zarovich in Season 2.
Philge and Raul had a high-profile romance in the weeks before Season 3, causing her much embarrassment when Bobby found out. Raul also with had a close relationship with visual effects specialist Glitter Gleam.
Raul's name appears to have been drawn from a list of fake American-sounding names for baseball players that appeared in the Japanese SNES game Fighting Baseball.
