Connor Cooper is Sydney's younger brother. He has a raccoon appearance, reddish brown, black stripes and mask, and brown eyes.

Connor is a fearless and a brave young raccoon/fox with a strong sense of adventure. He often doesn't consider his own personal safety, like in when he runs over to Ice Blister and hugs him, despite knowing he's a dangerous animal. Initially, he seemed to have no respect for higher authority, with regards to his mother. Connor is also mischievous but very sweet and good-natured.

Upon their first meeting, Connor and Dexter immediately took a liking to each other as Connor was fascinated with Dex's species, (as Sydney states, Connor is fascinated by everything).

Connor fights using a cane like his sisters and is surprisingly good with a gun for his age.

He is also very intelligent as he has read and understood quickly the strange symbols and languages of Raiden's world.

Trivia:

Connor is named after his paternal grandfather.

His full name is Connor Galleth Cooper. His middle name is from his ancestor.

Connor is 12 years old. Kane is 15, Sydney is 14, and Sally is 9.
