Who Wins in a Free-For-All Between Five Different Types of Undying Immortals?
Goal is to be the last one standing whatsoever, generally such that the winner has more agency than anyone else and is able to live their very long life unbothered by any of the others. Temporary alliances are allowed, but no permanent peace treaties - nobody can rest easy knowing the others are out there. Anything's on the board and defeating the others doesn't mean they need to die per say, just to be generally rendered harmless or incapacitated.
The combatants are:
Looper, someone with the ability to "Save" and "Load" the time and world state at will with a thought (reverting to the most recent save automatically when slain unless they would, in the same cognitive capacity as themselves in their previous save, choose to "Give Up" at which point they permanently die). This individual gets only one save slot which must be overwritten in order to Save further. Think a typical RPG save/load mechanic, like if Skyrim's system only had one save, or if you could save at any point with Undertale's SAVE system.
- If this is too powerful, all other combatants are aware of the reload when it occurs and maintain their memories.
Swapper, someone who, on their death, is replaced with an alternate universe version of themself within 5 meters of the location of death. This alternate self could be radically different, having made different choices in life, and might be from a reality with a radically different style or aesthetic, but their goal (winning this battle) remains the same. This AU self also swaps following these rules and so on and so fourth.
Cloner, someone who, on death, respawns with an exact copy of their body at combat start from an indestructible machine the size of a car with unlimited power and clones at a set hidden location. They choose this location before combat start but cannot move it. This self has all of the memories and personality their prior did up until point of death but is a SOMA or Transporter Problem sort of clone who is technically a different consciousness, if that matters.
Regenerator, someone with a conventional regeneration powerset akin to Deadpool or Wolverine, able to regenerate their body from minute instances of themself (such as, and up to a drop of their blood, as the maximum for their potential). The Regenerator does not age.
Lich, an evil freak whose soul is Barred from the Afterlife. Presume they function as a conventional fantasy Lich in respawn mechanics alone (such as one from Dungeons and Dragons Fifth Edition or Pathfinder 1st Edition) and can reappear at the site of phylacteries within 1d10 days. They start with two phylacteries, which can be destroyed, that they decide the initial location of and can create a new one through several days of ritual sacrifice of a human being. After respawning for the first time, looks like a skeleton.
All combatants are otherwise identical aside from phenotypal variations so they're not confused for each other, and they're all relatively fit and atheltic humans in their early twenties at combat start. They start in a circle each approximately 20 meters from each other.
R1: Set in the present, these fools all appear right now in Central Park in New York City. Combatants are fluent in English and Spanish.
R2: Set at the beginning of recorded history, around 3100 BC, in Mesopotamia. No combatants age, and combatants are fluent in all languages in the area.
Feel free to ask for clarification on rules or to logic out what you think makes the most sense.
