I don't have a definite answer for that. You'd have to look closely at various DC Comics issues and maybe check official character bios to get a clear idea of their ages and who's older.
To be honest, the age of Cynthia Lance in DC Comics isn't commonly known. It might vary depending on different storylines and continuities. You could try digging through dedicated DC Comics forums or fan communities for more accurate details.
Yes, DC Comics is older than Marvel. DC Comics was founded in 1934, while Marvel Comics was founded in 1939.
Roy Harper is a DC Comics character who is known as Speedy and later Arsenal. He's a skilled archer and a sidekick to Green Arrow.
Not much. Will Harper isn't a prominent or widely-known figure in DC Comics.
DC Comics has the edge in terms of age. DC started in the 1930s, laying the groundwork for superhero comics. Marvel followed a few years after, but DC's been around longer. Their early characters like Superman and Batman have been iconic for decades.
No, comics have a longer history than manga. Comics originated in the West much earlier.
In some ways, yes. DC Comics often delves into deeper, more brooding themes and has darker-toned characters and storylines.
It's not a straightforward comparison. DC Comics may present a darker tone in many cases, with more complex and morally ambiguous characters. However, Marvel can surprise with dark plots and intense situations too.
Generally, Batman came onto the scene before the Joker. The Joker's creation was in response to Batman's presence. So, no, the Joker isn't older than Batman.
DC Comics offers a darker and grittier tone in many of its stories, which some people prefer over the more lighthearted and humorous approach of Marvel Comics.
