Big Red was a presumed villain who turned out to be a good citizen back in 1870, before Ms. O joined the squad. He loves the color red and loves getting mail (he has 12 mailboxes). He is also the one that invented and built the Tube System. Since Big Red is red-haired, all the Tube Operators at Odd Squad are also red-haired.
