Why did I suddenly awake in a huge fish tank? Did I get reincarnated as a fish? *Looks down at myself* ...do fishes nowadays have an upper body of a skeleton or is it just me? Also who's the fellow skeleton mer beside me? They look like... Dream sans?! What the hell? What is this? Is this a freaking dream because if it is this is not funny!

What if someone died and was reborn in an undertale au as a siren? And not just any kind of siren, but a sans, a skeleton siren. They can change back between full skeleton form and back to their siren form. (Everything is different, different personalities etc, also includes all aus that I use, like a mixed au?

What if someone was reborn as underswap sans with gamer abilities? (So this was a request kind of thing and I did have another one in mind with this but with it happen differently kind of thing so there will most likely be two reborn as underswap sans with gamer abilities but I'll probably use a different name for it. Also different personalities, different beginning, deferent ending, different everything idk yet

What if someone became cross from xtale after the au was already gone? This cross doesn't really know much about xtale to begin with and has none of the original cross's memories to go with it either. That and the chara that he shared a soul with wasn't even there, he was just alone in his au. Sure he was confused as to how he became cross but shrugged it off and just dealt with it until someone came. (Different personalities etc different everything and all that. Different beginnings and different endings etc Help me decided who meets cross first.

I somehow become killer sans!? (Different everything, different beginnings, different personalities, different multiverse, multiverses etc

What if someone from our world became error and didn't destroy au's and left that for nightmare and his gang and claims au's? ( different things including personalities

What if when gaster fell into the core and his soul shattered...what if he was reborn as a human that had knowledge from there first life from our own world? What if...gaster didn't remember that he was actually gaster but though he was a human from our own world with those memories and knowledge from our own world...well up until sometime after meeting sans and papyrus's aus.. (Different everything, different personalities can just different
