The Swaplocke is a Nuzlocke to be attempted by two players, each with their own copy of the game. It's a cooperative Nuzlocke, and should be played simultaneously. The goal is for both players to beat the Champion of their respective game and win together.
Both players must use games within the same generation, but don't have to use the same version. The games used must be able to trade with each other, which is why having them in the same generation is mandatory. Both players must agree on the extent of this rule, and whether or not they'll allow differing regions within the same generation.
- For example, you could have one player using Pokemon Diamond, and the other player using Pokemon Pearl.
- If agreed on by both players, one player could use a game taking place in one region, and the other taking place in another. An example of this would be if one player uses Pokemon X, and the other player uses Omega Ruby.
This game could be expanded upon with other Nuzlocke variants, such as the Wedlocke, SoulLink, or Wonderlocke, but should always remain cooperative.
- Players may only catch the first Pokemon of each route (unless it conflicts with another rule.)
- Players must nickname all Pokemon caught.
- If a Pokemon faints, it is considered dead and must be released/permaboxed
- Players cannot choose the same starter. For example, if Player 1 chooses the Fire type starter, then Player 2 must choose either the Grass or Water type starter.
- Players cannot catch the same Pokemon on the same route. If Player 1 catches a Pidgey, and Player 2 encounters a Pidgey as their first encounter, they must re-encounter until they encounter something else (or until a catch limit is reached, if implemented)
- Both players must have the same number of Pokemon in their party. If one player cannot have a full party, then the other player must deposit any surplus Pokemon until both players have teams equal in number.
- After both players have beaten a gym, players must both roll a six-sided die. The Pokemon in that slot in their party is then traded to the other player. This traded Pokemon cannot leave that player's party until the next gym is beaten, or until it dies, whatever comes first. Players may not change their party before the trade.
- If a Pokemon is traded from one trainer to the other and stays alive until a gym is beaten and is not traded back to their original trainer, the trainer currently in possession of it may place it in their box if they wish. For example, if a Kirlia is traded from Player 1 to Player 2 after the defeat of their second gym, and the Kirlia does not die by the time both players defeat the third gym, and it is not traded back to Player 1 after said third gym, then Player 2 now has the option to remove it from the party if they wish.
- Both players must use different Pokemon from each other. For example, if Player 1 has a Scraggy on their team, Player 2 cannot use a Scraggy or Scrafty on their team until Player 1's Scraggy is removed from the team or killed.
- Both players must use Pokemon with different primary typings. For example, if Player 1 has an Espeon, then Player 2 cannot have any primary Psychic Pokemon on their team. Player 1 also cannot have any other primary Psychic type Pokemon on their team. An exception to this rule are Normal type Pokemon. Both players may have one Normal type Pokemon on their team. Bird Pokemon that are Normal-Flying type may count as primary Flying type if both players agree.
- Shiny Clause: If a player encounters a Shiny Pokemon, it may be caught regardless of the rules. The player who captured this Pokemon may choose whether or not to include it in the Swaplocke. If they choose not to include it, this Pokemon must remain in the PC unless it's transferred to a different game outside the Swaplocke. However, if this Pokemon is included in the Swaplocke, it is susceptible to all other rules, which means it can be traded between trainers.
- If one player whites out, or loses all their Pokemon, the other player has the option of lending the losing player a Pokemon or two from their game, to keep the Locke from ending. If the lending player has no Pokemon they can send, then the Swaplocke ends and both players lose. The lending player may not lend a Pokemon to the losing player if they have less than or equal to six Pokemon total, and they can only send a Pokemon that isn't currently a member of their party. The lending player may send up to three Pokemon to the other player. The original trainer of the lent Pokemon does not matter.
- The Swaplocke is over only once both players have defeated the Champion, or if one player has no Pokemon left. (Players must agree whether they can continue from a team wipe with boxed Pokemon or not.)
- Legendaries may or may not be used, but their inclusion must be agreed on by both players. If playing with default rules, they are not recommended. (Players may catch them with the intent to send them to a different game, similar to Shiny clause.)
Any other modifiers, such as item and catch limits, can be compatible with this locke, but both players must agree on what rules are implemented. The Swaplocke can be made as easy or as difficult as you want, as long as both players are able to follow the set rules.
