What is the behavior of Kevin in Freak the Mighty?

Kevin, also known as Freak, has a small crippled body with an enormous brain. He speaks as if he already has a PhD in science and sometimes acts like a knight in King Arthur's court. He has so much knowledge in his head about chemistry, robotics, computers, and literature that it flows out into his language and behavior. His best friend Max doesn't understand most of what he says, so Kevin decides to introduce him...

Kevin, also known as Freak, has a small crippled body with an enormous brain. He speaks as if he already has a PhD in science and sometimes acts like a knight in King Arthur's court. He has so much knowledge in his head about chemistry, robotics, computers, and literature that it flows out into his language and behavior. His best friend Max doesn't understand most of what he says, so Kevin decides to introduce him to a dictionary to improve communication. Speaking of Max, Kevin actually scares him when he first moves into Max's neighborhood. Because Kevin is so scientifically minded and imaginative, he points a crutch at Max and orders him to identify himself. Kevin also calls Max "Earthling," makes his crutch out to be a gun, and then makes shooting noises while Max tries not to trip over his shadow with his big feet. Max describes how he felt afterwards in the following passage:

"Scuttle into your dim hole in the ground, Maxwell dear. Big goon like you, growing about an inch a day, and this midget kid, this crippled little humanoid, he actually scared you. Not the kind of scare that makes your knee bones feel like water, more the kind of scare where you go whoa! I don't understand this, I don't get it, what's going on?" (10).

Most kids would probably be intimidated by Kevin's behavior as well. He's definitely quirky. Kevin dominates verbally whether he is speaking to kids or to adults; so, he's probably misunderstood verbally, and underestimated intellectually and emotionally. Fortunately, Kevin's behavior becomes even more confident as he is carried around on the shoulders of his new best friend Max. He also proves to behave courageously, loyally, and selflessly when his friend is kidnapped and almost killed. And when he also faces his own death, he thinks of Max first by telling him not to worry, he'll get his bionic body eventually.
