Villains from both worlds merge into one: Octo Petey. This piece showcases the battle environment as well as the boss; displaying how the character would move around the sunken building with the ink streams. Don't fall in the polluted water!
An (unofficial) illustration; I wanted to make it feel like it was a real promo for this theoretical crossover of Super Mario Sunshine and Splatoon.
A painting of Mario and his "squid" form. The squid form was based off of the Gooper Blooper: a boss from the game, Super Mario Sunshine. I tried to make sure the theme or references of the game stayed intact for the crossover.
Some of the preliminaries for making the Octo Petey boss fight.
I created these series of concepts and illustrations that merges two video game universes together: Super Mario Sunshine and Splatoon. These are not official concepts for the Nintendo franchises, but more so a fun idea and exercise. A "what if this were to happen" sort of thing! It eventually became known as "Splatshine".
