Is There Like a Skater and/or emo Anime??

for skateboarding animé I couldn't really find much but many people did recommend to others asking your question to watch Air Gear and Eureka Seven link
link as for emo animé I'm not sure about there being anything emo specifically but there are many Gothic/horror themed animes. so toi might want to try the gothique theme.

Try [K] Project, there is a patin, patinage boarder called Yata and he is awesome! =]
