Max is known to be very intelligent, as he reads lots of books and originally wanted to become a librarian. He was shown to originally have a childish side as well, reading Cow the cow.

Max is very enthusiastic about research, constantly dragging Runt and co to the library for one reason or another. However, when it comes to social interaction, Max struggled initially due to being very egotistical, although this improved over time. He is also a bit of a prankster.
