Tbh that's exactly how comics crossovers are written too. There's a vague plot they all follow but it's obvious that the various writers didn't know what exactly happens in each other's issues until after it's too late.

I read the "Atlantis Attacks" event recently, where the bad guy wants to revive the evil god Set. His plan is to get Atlantis and the surface into a war and use the blood sacrifice to revive Set.

So naturally, he spends the first couple issues making a giant serpent crown, turning random people into snake people and collecting 7 brides for Set.

He eventually gets Atlantis to attack the surface, hoping that they will be killed or the surface will retaliate and destroy Atlantis.

Next issue, rather than waiting for the outcome of the battle he summons a sea monster to destroy Atlantis, its blood poisons the waters and he decides that the decimation of Atlanteans is enough for the sacrifice.

Next issue, he decides he needs to genocide them and nukes Atlantis.

Next issue, he announces that without the blood sacrifice his original plans are ruined. Regardless, turns out some gizmos and the power of one of the seven brides is enough to revive Set.

Next issue Set is defeated and torn into 7 pieces by Thor and Dr Strange.

But he has 7 brides and a giant serpent crown which are apparently also the ingredients needed to reunite the pieces of Set. Needless to say, he gets defeated for good before that happens..
