Robin's doppleganger was not shown on Himym properley but it basically just looked like Robin with cropped hair and a dirty face she was carrying a baseball if I remember correctly and also a checked shirt and washed out jeans and old (maybe men's) trainers Barney, Lily, Ted , Marshall and Robin all saw lesbian Robin at the same time it seems according to Season 5 episode "Double Date" she was just casually walking along the street and spitting on the floor.
2. Moustache Marshall......
Again Marshall's Doppleganger was not shown properley on Himym it was just featured as a flashback on again The episode "Double Date" of season 5 not much was revealed about moustache Marshall apart from they all found him on a bus advert..... He was also found in maclaren's flirting with a blonde female he was wearing a brown suit with a burgundy tie and dark brown/ light black??? loafers.
3. stripper lily ( Jasmine )......
Barney and Ted were the first to see lily's Doppleganger and surprisingly Striper lily was found in her usual habitat...A STRIP CLUB!!!! she also made an appearance in season 7 again in a strip club she was wearing a pink and black lace corset with a black mole on the side of her face big ginger hair and thigh high boots.
4.Mexican wrestler Ted.....
Ted's dopleganger was also shown in season 5 in one of the last episodes of the 24 shown on TV Barney, Lily and Marshall were the first too see him but texted Ted the picture whilst he was at a party... Mexican wrestler Ted was wearing tight lycra silver shorts and black mid length tights with frizzy medium length hair thick eyebrows and a thick layer of guyliner.
5.Fertility doctor Barney......
Barney's doppleganger was played out a few times by barney himself and in the last episode of season five Lily claimed she saw Barney's doppleganger (a guy selling hot dogs) but midway through season six in the episode "Bad News" they met his real one he was wearing a long white lab coat light brown pants a pale blue pull over jumper and black loafers glasses and had dark brown hair and a fluffy beard.
