Dragon Ball - Season 1 Episode 38 Five Murasakis

Unable to finish Goku off with the boomerang shuriken, Murasaki uses his final ninjutsu, Bunshin no Jutsu (Split-Image Technique). Having somehow increased to five people, the Murasakis each take out their different weapons! Unable to tell which of them is the real one, Goku has no choice but to run! However, it turns out the Mursakis are merely a set of quintuplets. Now aware that they are all real, Goku uses Zanzouken to defeat four of them in the blink of an eye. With no other card to play, Mursaki calls forth Artificial Human No. 8!!
