Giles, Willow, Xander (Buffy the Vampire Slayer). The talisman Willow is carrying was inserted into the cartoon some years after the cartoon's debut. Initially the only visual cue for when Buffy the Vampire Slayer/Angel characters were visiting other fiction planes in The Hero of Three Faces was the transport effect seen here, which could only be used in scenes when they actually were in the middle of transporting. Since then I've inserted the talisman into all panels depicting anyone using or having used Willow's spell (including the Rogue One squad, who succeed to the talismans here), including retroactively, and added notations in this space that that's what the talisman signifies, like the ubiquitous editor's footnotes in Green Lantern comics reminding you, every time it comes up in dialog as a plot point, that the ring is ineffective against anything colored yellow. Sometimes, in order to give them better exposure in this, I go back to cartoons with the Doctor where the dialog could have been given to any time-traveler, and I edit the art so it's one of these guys instead.
