I think it is Big Bad Beetleborgs
Set in the fictional town of Charterville, three "typical average kids", Drew, Jo and Roland, enter the supposedly haunted Hillhurst Mansion after accepting a dare from rich snobs Van and Trip. The house is revealed to be the home of real monsters when the kids accidentally bump a pipe organ, releasing a phasm named Flabber. He proves to be friendly, and in return for releasing him, offers to grant them one wish. They wish to become their comic book heroes, the Big Bad Beetleborgs. However, this also brings the Beetleborgs' sworn enemies to life: the Magnavores, led by the evil Vexor, who would summon monsters from the comic books to battle the Beetleborgs. Roland's mom and dad run the comic book shop along with his grandmother Nano. In a 6-parter, Vexor created his own Beetleborg, Shadowborg, which was a match for the Beetleborgs and briefly took their powers. They had to call a temporary Beetleborg (White Blaster Beetleborg) Josh, and after Shadowborg was destroyed, Josh lost his powers. The Beetleborgs would meet the Beetleborgs comic creator, Art Fortunes during this six part story in order for him to create the White Blaster Beetleborg and the Mega Blue Beetleborg.
