I can see the reasoning to split but there have been two schools of thought about this for comics Obviously Green Lantern or Robin are examples of a superhero name taken by several individuals but the standard seems to be to create a main article about the character name legacy and give some details about each If more detail is needed warrented provide a link to the main article Obviously this is also affected by the significance of the character Starman comics for instance gives descriptions of all of the many characters with that name but only re links to those individuals who have been notable using that psuedonym For Shadowhawk it seems as if the mantle of this character was passed cleanly from one person to another so I d say keep it all in one article as with articles such as Phantom Lady or Black Canary
