Wamario was an evil version of Mario. Nintendo created him with the Wa-Machine, because they needed more haters. Wamario appeared in a few minor shames before his appearance in Super Daisy 64, where he worked for Wadaisy and tried to stop Daisy from taking back her castle. After failing three times, Wadaisy killed him. Later on, Wadaisy put Wamario's body and those of Wawaluigi and Wabowser into the Washing machine that is convenientently located that fuses/kills people. The three of them were fused, creating Wabowarigi.
