Frankenstein

The Frankenstein is a Hardmode enemy that spawns only during a Solar Eclipse, during which they are as common as zombies. Hitting much harder, having more life and walking faster, they can be considered "super-zombies".

They are one of only three (the others being Swamp Thing and Mothron) enemies that drop the Broken Hero Sword, which is necessary for crafting the Terra Blade.

Trivia

 * Frankenstein is a reference to the namesake 1931 film, as the theme of Solar Eclipse enemies is classic horror film icons.
 * Terraria propagates the common misconception that Frankenstein is the name of the monster rather than the doctor who created it.
