The character is a crossover between Craftman tools and DC Comics.
Have you ever wondered who changes the lightbulbs at the Hall of Justice? Most people would answer with a resounding "no", but DC plans on answering the question at the upcoming New York Comic Con. In a
marketing gimmick crossover with Craftman Tools, DC Comics will introduce the Technician, a character that acts as the Justice League's maintenance guy, in a comic book released by the two companies at the comic book convention.
Written by Josh Williamson (who also helped out with the famed Subway/DC crossovers last year), the character has been shown fixing Wonder Woman's invisible jet (has that made a New 52 appearance yet?), changing the spark plugs on the Batmobile (likely pissing off Alfred) and threatening to drill Flash's feet to the ground if he continues to scuff the recently polished floors of the Hall of Justice. The comic book will also feature Cyborg, the Key and the Royal Flush Gang.
So if you're attending NYCC and get worn out with the constant hobnobbing with comics celebrities or attending exciting panels, be sure to check out the Craftsman Tools booth, which will be handing out free copies of the comic. Tools are awesome, after all.
