His real name was Jimmie Foxx, but he was nicknamed the Beast because of his imposing physical presence. Foxx is one of the all-time greatest sluggers: a two time World Series champ, a three time MVP, winner of two batting titles. Foxx led the league in home runs four times, RBI three times (despite playing at the same time as Ruth and Gehrig), and hit 534 career home runs.

Unfortunately for Cubs fans, only three of those home runs came with the Cubs, who picked him up one year after his last good season. He hit .190 with the team in 225 at-bats, and was released in 1944. He later managed one of the women's teams during the war, and was the inspiration for the character played by Tom Hanks in "A League of Their Own."
