George Lucas frågade den här frågan under filmen av "Revenge of the Sith". Svårt att säga, hans svar var varken illuminerande eller särskilt meningsfullt.
"So how did Anakin get that scar, George?" asks John Knoll.
"I don't know. Ask Howard," says George, referring to President of Lucas Licensing Howard Roffman. "That's one of those things that happens in the novels between the movies. I just put it there. He has to explain how it got there. I think Anakin got it slipping in the bathtub, but of course, he's not going to tell anybody that."
Boken som han hänvisar till är "Darth Vaders uppkomst och fall", som informerar oss om att hans ärr mottogs under en duell med Asajj Ventress.
Lethal droids were not the only adversaries to the Jedi, as Count Dooku had recruited such deadly beings as the Sith aspirant Asajj Ventress and the nearly indestructible Gen'Dai bounty hunter, Durge, to fight on his behalf. Dooku himself had trained Ventress in the art of lightsaber combat, but often ridiculed her preference to wield two lightsabers at the same time. Anakin nearly defeated Ventress on the fourth moon of the gas giant Yavin. One of their duels, in the industrial sector of Coruscant, left him with a deep scar on the right side of his face.
Vi får faktiskt se den här händelsen i serien Serie Republic 71: Dreadnaughts of Rendili, del 3
