Blue Beetle by Keith Giffen

When Jaime finds the scarab, he thinks it's just a cool looking rock and takes it home.  The rock is actually alien technology, and one night it comes to life and fuses itself to Jaime's spine.  Now, whenever Jaime's in trouble, the scarab kicks into action, covering Jaime's body in blue armour and protecting him from danger.  The armour also enables Jaime to fly, which is really cool.  What's not so cool is that the scarab is an alien artificial intelligence, which means it thinks for itself.  That's a problem, because the scarab thinks the solution to every problem is to kill somebody.  If Jaime doesn't want to be known as a supervillain instead of a superhero, he's going to have to find a way to control the scarab.  That means he's going to have to find a way to communicate for it.  Unfortunately for Jaime, the scarab only speaks an alien language.

Superhero graphic novels are a must if you're going to booktalk to boys, so I am always on the hunt for good titles.  There are plenty out there to choose from, but this one also has a multicultural hero, which always makes me do my happy dance.
