Enemy Mine: Tabletop Games
- Magic: The Gathering has a number of scenarios:
- Almost all cards in Magic: The Gathering are divided into one of five categories, defined by certain characteristics and assigned a colour. The five colours are seen on the back of the cards in a pentangle. The characters and creatures associated with any particular colour are hated by the colours on either of the nearer points, but even they will ally to fight against a colour further away (physically and thematically) from one of them.
- This forms a significant part of the dynamic for the good guys in the Archenemy variant (since they can easily be colors that either do or would hate each other slightly less than they hate the main opponent).
- The events of the Zendikar block have the vampires, elves, humans, Kor, minotaurs, goblins, merfolk and what-have-you uniting against the Eldrazi).
- In the Scars of Mirrodin block, the Mirran forces in all five colors were forced to team up against Phyrexia... although the Black-aligned section was wiped out by the second set, and Phyrexia won in the end.
- Mage: The Awakening generally sees the Pentacle Orders locked in battle against the Seers of the Throne, with Banishers attacking both sides. However, when The Mad, Reaper Legacies or the Abyss-aligned Scelesti show up, all three sides will most likely declare a truce to stop them.
- Mage: The Ascension has pretty much the same dynamic, with the Traditions and the Technocracy setting aside their conflict long enough to take down a Nephandus or Marauder.
- Werewolf: The Forsaken does the same thing as well, with the Forsaken and the Pure reluctantly willing to put aside differences and put down Bale Hounds or the Idigam whenever they pop up. An entire Lodge, the Lodge of the Hunt, exists to invoke this trope, bringing together werewolves who have a common Arch-Enemy.
- Warhammer 40,000 very, very occasionally has instances where the more reasonable factions will hold off on killing each other to deal with a mutual threat. For a few minutes, anyway.
- This most common variant occurs between forces of the Imperium, Eldar, and Tau against Tyranids, Necrons, or Chaos, and matching temporary alliances may occur between Chaos, Orks, and Dark Eldar, as prominently seen during Dawn of War: Winter Assault.
- The Eldar, being who they are, will often manipulate any allies they do make so that they take the brunt of the fighting (and thus causalities), in essence back-stabbing their allies during the alliance, as well as overtly so 5 minutes before its usefulness ends. Their evil cousins, the Dark Eldar, pretty much always do the same.
- Dawn of War II has a new mode which exemplifies this, known as "The Last Stand", where a Space Marine Captain, an Ork Mekboy and an Eldar Farseer cooperate to Hold the Line against a swarm of enemies. The Chaos Rising expansion throws the Chaos Sorcerer and the Tyranid Hive Tyrant into the mix of heroes in the play mode, which technically cements— if it wasn't apparent with the widely opposing team we had before— that the game mode is not to be taken as canon, especially when a loyalist Marine cooperates with a Chaos Marine in any way.
- Rules for the 6th Edition allow "allies"; if the player's army allows, they can take a HQ and a Troop choice (or more if they really want to) from another army. Specifically, the categories Desperate Allies and Unholy Alliance allow players to invoke this trope if they want.
- In Paranoia, even if someone's ideology is directly opposed to yours (Psion vs. Anti-Mutant, Corpore Metal vs. Frankenstein Destroyers), alliances can always shift to suit the demands of the moment. You can always hose them later.
- Several years ago, Arcanacon in Australia featured a freeform called "Mars Attacks! the World of Darkness". The blurb for the game included:
Will the Camarilla fight alongside the Sabbat?Will the Garou fight alongside the Wyrm?Will the Traditions fight alongside the Technocracy?Will the Seelie fight alongside the Unseelie?...and will the Malkavians fight alongside the Martians?
- Just about all the Successor States in BattleTech was quite happy to blow each other to kingdom come. And then the Clans came, and all of a sudden, Arch Enemies were forming alliances to stop the threat. A few decades later, the Word of Blake started nuking everyone. So the Successor States ended up forming an alliance with the Clans to nuke the Blakists back.
