"'Can we just say the Knight is terrible and leave it at that?'"

Summary
Jerome Noble is the Squire, the former Sidekick to the Knight, the main hero of Bedlam, Maine. Due to a combination of horrible luck and the Knight being a horrible Mentor, Squire gained a reputation for getting his teeth kicked in and eventually went solo, moving to Starlight City, under the guise of attending college at Vanderburg University

Every Kid wants to be Robin, right?
Jerome Noble was born the son of Bedlam millionaire-playboy Franklin Noble, a man who had already for reasons that are his own become the superhero the Knight. Up until he was 12, Jerome took a backseat to his father's superheroics, and was not involved in it. As a gift on his 12th birthday, he was officially sworn in as the Knight's sidekick, the Squire.

Also on his 12th birthday was the first time he was hit in the back of the head and kidnapped while in the field by one of the Knights enemies, which prompted the addition of a helmet to his costume...after it happened 7 more times.

It was a bad idea to send a child with minimal training into situations involving insane and violent criminals, Who knew?!
Over the next 6 years Squire would gain experience and become a formidable fighter in his own right. He would also be kidnapped by criminals and held in a variety of death traps too many times for him to count, including once being kidnapped by Copper Spider and Spiderling, though this event was likely one of the less dangerous situations he was put in during his career as Knight's Sidekick.

This event caused a falling out, with the Knight angrily telling off Squire for not understanding that he had to put capturing and stopping supercriminals first. Squire took this...reasonably well. He trashed the Knight's headquarters before moving to Starlight City to attend college.

Present
Currently Squire is living in the Castle, a themepark he bought and renovated through funds he had access to for "Emergency Crime Fighting use". He is also attending Vanderburg University and acting as a hero in the area.

The Squire (Nitro Comics Version)
The original version of the squire appeared in the Nitro Comics universe as one half of a rather rude Batman and Robin parody that portrayed there Batman Espy (The Knight) as a Jerkass Manchild who was at best neglectful of the far more competent Squire. Through fan mail at the time it was discovered Squire was popular enough that he was folded into the main comics universe as a member of The Prodigies, a Teen Titans like group during a fan favorite run. After Nitro Comics was bought by Night Sky Comics, his time with the Prodigies, and the group itself, was retconned from existence, resulting in the new Canon version above.
