Excerpts from wgntv.com:

The Chicago Police Department and the Chicago Fire Department teamed up with Make-A-Wish on Sunday to turn Navy Pier into a comic book adventure and help a boy play superhero for a day. 

Nine-year-old Cyrus Powers from Portage Park has cystic fibrosis and  wished to become the superhero “Minds-Eye.”  His mission: to save Chicago from the evil “Dr. Laugh,” who freezes his victims and steals their valuables. Powers got to work, putting together a team to arrest Dr. Laugh and unfreeze his victims. 

After the bust, Cyrus was presented with leadership awards as an honorary superhero police officer. 

Cyrus also got another surprise: Navy Pier installed a giant version of his uniform’s insignia in the middle of the ferris wheel.
