Has anyone at DC ever called him a "threat"?
Jay Garrick is getting screwed!!!
I don't know who says that. I said he needs something.
I think She-Hulk is a great example of taking a conceptually derivative character and turning them into something more worthwhile. Originally she was little more than a gender-swapped Hulk. Then they hit upon the idea of her loving being She-Hulk, made her a fun and sexy character, made her second series a fourth-wall breaking comedy that played with conventions of the format and genre.
Green Lantern's better equipped at handling multiple heroes, since it's baked into the concept. When the concept is "the fastest man alive", there's less wiggle room. Still, DC hasn't been in any rush to give the secondary Green Lanterns a solo series. Team-up series, sure.
If Marvel owned Flash, we'd have seen multiple spin-offs by now. For whatever reason, DC is more conservative about spin-off series outside of their Batman titles, and more so about giving a cancelled series a second shot.
You think wrong. I don't like how DC is currently handling the character.
Wally West, as he is, can continue existing in the relatively limited capacity he currently is. But fans on this forum are constantly demanding an ongoing solo series and a more prominent role in the DC Universe. If that's going to happen, then there needs to be something significant to set him apart from Flash (Barry Allen) and Kid Flash. Otherwise, he can continue being the Kyle Rayner.
