Hi! Thanks for bringing this to our attention! However, I should let you know that just because some serieses may crossover, does not mean that they are in the same universe. Here's the way the Image Multiverse works, essentially:
Almost every series (except if they feature the same characters as another) should be classified within its own universe. Every universe has a version of each series within itself. For instance, the Youngblood program has appeared in Spawn, and vice versa, but after some of those intitial meetings things change. In Spawn, significant status-quo changes occur that would have otherwise affected the Youngblood title if they occured. But Youngblood does not acknowledge those parts of Spawn, meaning that it diverged from the Spawn unvierse after those initial interactions.
So in the case of Spawn and Youngblood, perhaps they started as the same universe, but now they clearly are not. Here's another example: Spawn appears in the Invincible War, alongside most major Image superheroes. Yet Spawn and Invincible cannot possibly take place in the same universe, for sooo many reasons that may be too long to list here. This means that the Invincible unvierse has a version of Spawn, who had similar adventures to the Spawn universe's Spawn, but not exactly.
Now this brings up another problem: should we create brand new character pages for all of these individuals? E.g., should we make a page for the Spawn who appeared in Invincible #60 and everyone else? My answer is no for now. Firstly, that takes a LOT of time, and we the admins would have to search the whole wiki and make these changes. Second, Image does not even establish its multiverse the way it should. As far as it's concerned, the real Spawn appeared in Invincible #60, without thinking or acknowledging the problems this idea causes. So if Image treats the characters as their real selves, so will we. If they change their stance, we'll equally do something about it.
I don't think it is my place to say, but perhaps you should only do this for Top Cow and its relaunched counterpart "Switch". As of yet I believe, this is the only example of two universes in the same partner studio of Image. Chaning the names of every other page would be complicated and time-consuming, wouldn't it? Unless this happens again (I'm not counting Invincible yet), I think someone would be able to figure out what universe a character was from by looking at a link like their first appearance, for instance. I do agree that Satan from Spawn should be considered a separate character than Satan from Highbrow, however, and examples like this should be followed to distinguish characters of the same name. The characters of "Switch" are, really, separate characters now, are they not? So, they should get their own pages because of that, to distinguish them from the Top Cow counterparts who are named the same. Basically, I think this should not be done.
