M versus N

Here we are at the end of my A to Z, but due to the odd format, also the beginning and the middle. I wanted to finish the project with a big picture stuffed with loads of characters, akin to E versus V, but something about this suggestion -- from my friend Liam as I recall -- grabbed me; perhaps I was drawn to the opportunity to have a go at some pixel art.

In this final A to Z image, Alan Moore's Nite Owl chases Nintendo's Mario for reasons unknown.
