Who is in the Obi-Wan Kenobi Cast? Star Wars series, Obi-Wan Kenobi. Obi-Wan Kenobi is in all 6 live Star Wars movies. The adult Obi Wan Kenobi costume comes with a tunic, hooded robe, pants and a belt. Spider-Man, Spider-Man, does whatever a spider can-which, in this case, is dressing up as Spider-Man or as Spider-Man from Homecoming (with a costume from Liking Cosplay). But dressing up is not the only way one gets to earn money in cosplay.
