Kurilien (クリリアン) is a video game-only alien villain that appears in the 1986 Famicom game Dragon Ball: Shenron no Nazo.
Kurilien is a four-armed alien fighter who greatly resembles Krillin, even wearing the Orin Temple outfit. He works for Monster Carrot, despite the fact of not being a member of the Rabbit Gang, and first appeared in Stage 11, "Monster Carrot's Revenge".
Akira Toriyama drew the concept art for the character, which can be seen in the strategy guide; the sprite in the game looks much different, due to the obvious graphics constraints of the time. Kurilien appears to have a long, alien-esque head, large pointy ears, and sharp teeth. In the concept art, he wields a spear and nun-chucks, and is described as the "#1 assassin in the universe". However, in the actual game, he does not wield any weapons and is incredibly easy to defeat.
- His name is most likely a combination of Kuririn (Krillin's Japanese name) and Alien.
- In the American version (Dragon Power), Monster Carrot calls him "Round Head".
