Boomerang vs Captain Boomerang
For all intents and purposes, these two characters are the same and can be used interchangeably. The only real differences between them is that Captain Boomerang was introduced by DC in 1960 while Boomerang was Marvel’s boomerang-wielding marksman who debuted in 1966. Both are primarily villains and both incorporate a myriad of gimmicky boomerangs in their deadly arsenal.
