The Shadow Blot

The Shadow Blot is the wholly revamped version of the Phantom Blot that appears in Epic Mickey. A destructive force of paint and thinner created by Mickey Mouse, the Shadow Blot has long rampaged Wasteland and seeks a way to escape it and continue his terror in Mickey's world.

Epic Mickey
When visiting Yen Sid's workshop and playing with magic paint, Mickey Mouse accidentally created a monster and quickly tried to erase it using thinner. However, what Mickey erased went back into the jug and fell into Wasteland, causing the Thinner Disaster and setting the Blot Wars into motion. Allying with the Mad Doctor, the Shadow Blot came very close to victory, only to be sealed away by Oswald and Ortensia, though at the cost of Ortensia's life.

Ever since that time, the Blot's presence remained in Wasteland through the various drippings that escaped the Jug, the largest of which has become the Blot's eyes and ears in Wasteland.

Continuing his work with the Mad Doctor and commanding the Blotlings in his stead, the Mad Doctor worked on a plan to allow the Shadow Blot to reach through the portal to Wasteland into Mickey's world and capture another toon to steal their heart. Selecting Mickey, the Blot dragged Mickey down into Wasteland, though the Mouse managed to bring Yen Sid's magic paint brush with him, frightening the creature off.

While Mickey travels through Wasteland to find rocket parts to get back home, the Shadow Blot builds his army up to assault Oswald's Fortress on Mickeyjunk Mountain and open the Jug. Mickey defeats the fake Blot on the mountain summit, but when Oswald discovers he was responsible for the Blot's creation, an enraged Oswald accidentally breaks the Jug open, releasing the real Blot.

Ransoming the lives of Oswald and Gremlin Gus for Mickey's heart, the Blot then proceeds to begin absorbing all of Wasteland's paint with Bloticles attached to the ground. Mickey destroys these connections and he and Oswald plan to hit him with the rocket. Absorbing the paint from the rocket and causing it to crash land in Dark Beauty Castle, Oswald comes up with another plan to defeat the Blot--bombard him with fireworks, setting the stage for Mickey's final battle where he must activate the fireworks and eventually gets dragged inside the Blot to get his heart back by force.

After breaking his heart free, Mickey's heart is given back to him by Oswald and the Lucky Rabbit hits the button to launch the fireworks, destroying the Blot in a series of colorful explosions that also serve to send Mickey back home.

Development
The Shadow Blot was present in the earliest concepts for Epic Mickey as the force that brought Mickey into Wasteland. As a revamped version of the Phantom Blot, Warren Spector intended on expanding the threat the Blot posed compared to his camera stealing motivation in his original appearance. The character's name was changed when the crew deemed that their revamped Blot had become very far removed from the original and in keeping with the "familiar but strange" feeling of the use of some characters.
