Just a little pic of the fight between Kirby and Nightmare in Kirby's Adventure or in my opinion it's superior remake, Nightmare in Dream Land. It takes place on the moon, but why does the moon have grass?
Unlike his animu counterpart, Nightmare only appears once in the video games.(not including his cameo in that one mini game in Mass Attack)
Where in the anime, he's the main cause of evil and started World War ? that went on for a gazillion years! Although in the games, Nightmare is an actual challenge instead of using one whip of the Star Rod in a dream in the anime.(seriously, that fight was pathetic!XP)
