Both final
Both fully evolved
The Both final connection is one of the evolution rules in the daily PokéWired Pokémon puzzle. Two Pokémon are linked by it when this holds: Both fully evolved.
It's not directional: it works both ways, so it doesn't matter which Pokémon goes on the left and which on the right. You'll meet it in Normal puzzles, and it can also show up in the Unlimited and Chain modes.
Evolution connections look at where a Pokémon sits in its family: which stage it is, how long its line is, and how it evolves — by level, by stone or by another method.
