Okay, so there'll be several shows where characters have some form of body part mutilated. In The Walking Dead and Game Of Thrones, it's actually uncanny as to how similar Merle and Jaime Lannister's injuries and personalities actually are. They both lost their right hand, they both gained metal replacements, and they both use their new 'attachment' in combat. As if that wasn't already enough, the characters themselves match up. They're both villainous, and appear to be the main antagonist after their Pilot episodes, though over time, Merle and Jaime gradually begin to redeem themselves and could even be considered heroes in certain moments.
