Unorthodox matchup. Invincible vs Novum Chaldea.
Novum Chaldea vs. the Invincible Universe
Been thinking about this matchup and wanted to see how people think it would actually play out.
For the setting, I'm going with Earth with both the FGO and Invincible resources/technology available. This isn't stat equalization; everyone keeps their normal abilities, physical stats, weaknesses, etc. The main point of the setting equalization is just to avoid one side being limited because they're in the other's universe.
Round 1: Guardians of the Globe vs. Novum Chaldea
No prep. Both sides have their standard resources and capabilities.
Round 2: Viltrumite Empire ( so all 50?) vs. Novum Chaldea
Same conditions. No prep.
Round 3: All of Invincible vs. Novum Chaldea + Mages Association + Solomon and his Ten Rings
Basically the entire Invincible side vs. Chaldea Mages Association. Assume the different factions on the Invincible side are willing to cooperate for the purpose of this matchup.
Round 4: Same as Round 3, but both sides get 1 week of prep.
For the prep round, neither side starts with knowledge of the other's abilities. However, they're allowed to use whatever information gathering/intelligence resources they already have.
So, for example, if Chaldea has something like SHEBA/LAPLACE or another system capable of observing, analyzing, or predicting information about the opposing side, they're allowed to use it. The fact that they don't initially know the Invincible characters' abilities doesn't mean they're forbidden from trying to find out.
Same goes for the Invincible side if they have comparable technology or abilities.
Basically, no free encyclopedic knowledge of the opponent, but you can absolutely investigate them during the prep period. Arguments can be made that the other side can't be observed or investigated if the team has specific counters from being spied on like in Dragon Ball for instance.
For both sides, any technology, weapons, facilities, Servants, etc. that they actually have access to are fair game. Prep time doesn't magically give them new technology they never possessed, but they can make full use of what they have. so if a character has done something before, they can do it again under their usual circumstances.
How far does Chaldea get? I will try to answer any questions about Type-Moon to the best of my abilities since it's convoluted, but also I'm not entirely familiar with specific individual Invincible characters so I would like to discuss those as well.
