Maximilian Alonzo Ernesto "Max" Russo is a former wizard and the youngest of the Russo kids. Like his siblings, he is half Mexican from his mother and half Italian-American from his father. He is portrayed by Jake T. Austin.
In the series's finale, Alex became the Russo Family Wizard and Justin a full wizard due to becoming the Headmaster of Wiz Tech. As a fall-back plan for becoming mortal, Max obtains the Sub Station which he seems very happy about.
At 16, he is the most mischievous, determined to take his magic "to the Max." When he's not dodging homework and vegetables, Max plays practical jokes on his siblings. His first spell (on the show) was "Comakus Pancakus" to conjure up a stack of pancakes.
It is very hard to tell at times if Max is eccentric, outside the box or just stupid. He takes almost everything said to him literally, often confuses the meaning of words (such as aunt and ant), doesn't seem to understand when he's being insulted even when told he is being insulted, and has been known to do some very idiotic things such as shrinking his own brain just so he can store more jelly beans in his skull. However he has been shown to be an average level student despite his intellectual shortcomings. In the season 4 premiere he claimed to be acting dumber than he really was so no one would believe him if he revealed he was a wizard.
His dumb personality makes him very innocent and simple. It is proved multiple times. During most problems and troubled times, he doesn't get even the least bit sad. Even when his siblings got to keep the powers, he was happy about being a mortal, basically because he never used magic and it wasn't as important to him.
