When Shrewd was created, he was meant to be Sir Sheath mild-mannered brother. But that idea has been discarded, and Shrewd has been reimagined as a thug for the Enmity Organization.
Shrewd is shown to be somewhat quiet, rude, and bad-tempered. He is a part of Enmity's muscle and usually tries to solve things through brute force. He also sometimes works under the command of Riff Wrath.
