Irregular Saturn (or just Saturn) is the alias of a Brazilian pixel artist who started making comics from a very early age. It was at the age of six when he produced his first hand-drawn paper comics about Mega Man X (1993). Saturn eventually moved to sprite comics once he discovered online sites where he could download original sprites ripped from the games. He originally envisioned his sprite comic Mega Man X: Unit 49 (2015) as a videogame, but became discouraged by the required skills or means to do this. With the creation of sprite comics in decline, Saturn considered quitting the practice, but in 2014 he was invited to join a sprite comic tournament in Brazil, called Nitrusland Escape Tournament, a fighting competition in which creators make strips with their characters battling other participants. A team of judges selected the best artwork and declared a winner for each round. Saturn won the tournament against more experienced artists, which renewed his energy to carry on with the practice. Sprite comics allowed him to develop the story he wanted to tell while learning useful skills in the process, to such an extent that he has been able to land some professional jobs, such as the creation of backgrounds for the indie game FictionSphere (2019).
The Mega Man franchise has been a popular subject in sprite comics, with original assets and multiple fan-made expansions available through sites such as Sprites-inc.co.uk and DeviantArt. Saturn normally downloads the sprites from these sites and modifies them if the poses he needs are not available. He also creates his own pixel art from scratch for original characters and backgrounds. Assets are composed around a comic layout in Paint.Net with layers reserved for panel images, panel borders, speech bubbles, text, onomatopoeias, watermark and a banner that changes each chapter. For Saturn, this franchise has enormous scope for fan creations due to the multiple unexplored areas of its lore.
For Saturn, his main motivation for creating Mega Man X: Unit 49 was to fulfil his childhood dream of sharing a story about which he is passionate with as many people as possible, and engage in constructive discussions with his readers, particularly those around the deeper sides of the story.
