Brass Knuckles

The Brass Knuckles are a robotic variety of Echidnas from a future version of Mobius. They are the most numerous enemy of the Freedom Fighters of the Galaxy.

Trivia
Their name derives from the weapon known as Brass Knuckles, which have been made illegal in a wide range of the U.S.
 * The Freedom Fighters of the Galaxy and their enemies, including the Brass Knuckles, currently hold the fifteenth-longest non-appearance gap in the main series, though it is unknown if they will return at all (StH: #104-#207)
 * Given their name, it is likely that the Brass Knuckles are intended to be descendants of Knuckles the Echidna. Their name is also shared with the hand weapons.
 * Whether intentional or not, the Brass Knuckles' mechanical nature makes them resemble the Cybermen of Doctor Who-fame.
 * In the Off Panel for StH #243, a version of Metal Knuckles known as Brass Knuckles is featured. However, this version bears little resemblance to the Mobius Galaxy villains.
