The End Monster is an End creature that got mutated, its regular eyes turned red, gained 4 extra eyes, and things at the end of its arms and legs.It was friendly before but the mutation made it Hostile.Its mutation was caused by it going through the End Portal to get to the overworld, since it was curious to see what the overworld looked like.Something went wrong while it went through the portal, causing it to be mutated.The only reason it got mutated in the portal was because 4 eye creatures went in at the same time, which is why it now has 4 extra eyes.Those eye creatures were hostile, which is why the end creature is now hostile, and is also why its regular eyes turned red.

It was also smaller before it got mutated, its now 2 blocks high.

(NOTE: Not sure if fits contest or something else, I just thought of this monster and decided to make the skin and enter it in the contest.)
