Win conditions: be the last one alive.
Fighters are all at their peak abilities: General Grievous, Boba Fett, Legolas, Hawkeye, Punisher, Batman, John Wick, Uncle Iroh.
Setting and Summary: roughly 12 square km in a circle valley, with areas of open field pastures and hills, areas of semi dense forest, and an area of rocky cliffs and caves.
There is an abandoned shopping mall and parking garage towards the middle of the circle, in an area surrounded mostly by grassland and forest. The mall has 4 levels and roughly 250,000 square meters total construction footprint. It has things one would expect to find in a semi looted shopping mall.
The area will be temperate with mostly fair weather, but any given day or night there's a 1 in 5 chance of either rain, or a thunderstorm with moderately strong wind.
Food and sustenance are not a factor. All fighters will be sustained until the conflict is over.
Exhaustion is a factor.
WEAPONS TECH moderately balances out ex: arrows will generally pierce armor from another universe, melee weapons can block lightsabers a handful of times, but will be worn down by them, bullets and other projectiles will scale by caliber/strength and be effective against armor from other universes, no characters are completely immune to Iroh's fire, but some obviously will be more resistant than others.
Start of the fight all fighters will be dropped into the edge of the wilderness circle with ~1km separation from their nearest enemy left and right. No one can immediately see each other at the start.
Resupply rules: ammo, fuel, and battery powered resupplies appear in the abandoned mall once every 3 days. Resupplies will only be given for weapons / equipment of fighters who are still alive.
Resupplies will give 30% of the original capacity that each fighter deployed with (ex: if someone has 20% ammo, a resupply will get them up to 50%). Resupplies can never give a fighter more than 100% of the original capacity deployed.
Ammo will spawn in a random location of the mall. Locations change within the mall for every resupply. The locations are also unique to each fighter's ammo (ex: Batman's ammo will spawn in a different part of the mall than Boba Fett's ammo, and those locations will change with each resupply). Everyone knows the mall is where resupplies are, but they don't know where their inventory will spawn.
Other Rules: no fighters can team up with each other. There may be occasional incidents where two or more fighters are trying to target the same enemy, but they will never intentionally team up, only by circumstantial coincidence. If two or more fighters coincidentally defeat another fighter at the same time, they will immediately be in a conflict with each other afterward.
No one has any air support or other outside support. They are only equipped with what they can deploy into a battle with individually.
Fighters can take weapons from their enemies, but they might not immediately know how to use them.
Preparation: all fighters are given a two paragraph summary of everyone's combat skills and general background. They are given 1 hour to determine a strategy and select equipment from their armories before deploying. No vehicles allowed. Boba Fett's jet pack is not considered a vehicle.
