Wario is extremely greedy and does anything to get money, as shown especially in the Wario Land series and in Wario World. He is also a miser, as he never lets anyone else touch his treasure. Sometimes, his greedy nature even overtakes him and he goes out of control occasionally, even going as far as to double-cross his friends. Wario is also known to be gluttonous and addicted to sweets, having even problems due to that, as shown in WarioWare: Touched!. He is also shown to be childish at times, which is best demonstrated in the ending of Super Mario Land 2, where he proceeds to cry like a baby after being reduced in size, only to punt his shoe at Mario before sticking his tongue out in a taunting manner while taking his leave.
