Montgomery "Monty" Adams is the main protagonist in the 6th Goosebumps Series 2000 book, I Am Your Evil Twin.


Monty's father died when he was two, leaving him to be raised only by his mother. As a zoologist, she had to go to Borneo for a year, leaving Monty with his Uncle Leo for a year, along with his cousin.

He started to see an evil version of himself running around, and found out that his Uncle Leo created an evil clone of himself that then created evil clones of Monty. He also discovered that his cousin Nan is actually his sister, who his mother had to give up when they were young.

Monty was mistaken for the clones and was hauled away. While he managed to escape, an evil Monty tricked Nan and Monty was hauled away to South America, along with the clones.
