Slimey is one of the two main protagonists of the Slimey & SMJ4 series. He is a small anthropomorphic shapeshifting green slime with a face similar to Meatwad from the Adult Swim series Aqua Teen Hunger Force.
Slimey is generally kind-hearted and has a mature sense of humor. He is often easygoing and very optimistic, like his best friend Justin. Although he is mostly friendly, he does get sarcastic and is easily irritated, much to the annoyance of SMJ4.blend1, who is one of Slimey and Justin's neighbors. Slimey is also somewhat cowardly and gullible, a good example of this is that an April Fools prank about nuclear missiles about to strike the entire United States caused him to think that the country was in danger, not realizing it was a prank Justin pulled on him. Under normal circumstances, Slimey is a professional slapstick artist, along with Justin. They both use comedic antics while fighting their enemies, most notably Jar-Jar Binks and Shia LaBeouf. Overall, Slimey is innocent and loyal to Justin and his friends.
Slimey and Justin are best friends and have so much in common with each other. They are both comical, outgoing and lighthearted. They also have very excellent skills at slapstick comedy. However, they will occasionally get annoyed of each other, especially if things don't go as planned.
Slimey and Justine don't usually interact with each other, but he will sometimes talk to her in case of big situations.
Slimey is often mindful of .blend1 and doesn't like him very much, same as .blend1 doesn't like Slimey, but .blend1 doesn't hate him as much as he hates Justin. Slimey is commonly irritated by his antics.
Slimey didn't really seem to care very much for his Creepypasta counterpart Slimey.avi. However, he has developed a close relationship with .avi as the seasons went by.
Mini-Me has actually been good friends with Slimey, because he is said to be the cuter and more innocent version of .blend1.
Slimey doesn't like Jar-Jar, much like most of the other characters, formerly excluding .blend1. He and Justin often try to put an end to his dark plans, since Jar-Jar is portrayed as a Sith Lord in the series.
