Apocalypse and his horsemen are teleported into Metropolis after a Celestial tech experiment.
Round 1: Someone calls the police and this is the league available.
Round 2: Apoc and the others manage to stay out of sight. Over the course of the year the groups have time to study each other without a direct confrontation and time to prep. (no sundip, sinister has captured many mutants/metahumans to study)
They are each put in the same timeframe in a merged marvel movie universe and given the same research facility and funds. Who's smarter and comes out on top?
Six months prep
One year prep
Ten years prep
What is are they going to do with prep anyway? We could speculate, but you can only assume make more armor/soldiers, but we dont know how fast they can do that.
We have no idea what limits they have with prep
The shorter time period was meant to favor iron man who did have superior feats in pulling a suit out of his ass.
In the longer run I would give the edge to Trask because he is not as much of an egomaniac. He built a foundation for a system that others could easily improve on even if he was dead. So I think he's a better manager and would be able to work better with a team for the ten year prep to basically make the future sentinels or better.
