When it comes to him being a purposeful reference by the original Japanese designer, that part is unclear (but absolutely possible, remember when an anime had the Angry Video Game Nerd and Nostalgia Critic in the background in one scene?), but I think it's safe to say the localizer handling dialogue noticed the resemblance and knew this would be the perfect time to sneak in a Critikal reference.

It really is hard to believe that this was all accidental.
