Familiar fans of the Pokemon franchise will already know that not every Pokemon evolves by leveling up. Certain species require trading, and then there are the species that have unique evolution requirements. Naturally, this carries over into Pokemon GO, where Pokemon don't "level up," but may require a trick in addition to receiving the right amount of Pokemon Candy.

Some of the Pokemon in Pokemon GO just need to be assigned as a Buddy and walk a certain amount of kilometers, but that isn't always the case. Evolution methods can have bizarre requirements, and some take longer than others. Knowing and checking which Pokemon have special evolutions will prevent trainers from being caught off guard.

For some Pokemon, there will be a tab beneath the Evolve button on the summary page. Tap the dropdown arrow to view the Evolution/Buddy Task and check its progress. Most Pokemon with this evolution method will need to be set as the Buddy Pokemon. To do this, tap the trainer icon in the lower-left of the screen. Select Choose a Buddy or Swap Buddies. A Buddy Pokemon can be changed up to 20 times a day.

The Pokemon doesn't necessarily have to be out of the Poke Ball/on the map for the completion of the task. Just make sure it's set as the Buddy before getting to work on the Buddy Tasks.

Every Pokemon with a Unique Evolution Method

Pokemon with Unique Evolutions are those that don't need to be set as a Buddy, but they do have Evolution Tasks. For a Pokemon like Tyrogue, the silhouette of what it will evolve into will appear next to the Evolve button. Others may have question marks and have little-to-no clues on how to evolve the Pokemon.

* Trainers can view their Pokemon's IVs by tapping the icon in the bottom-right of Tyrogue's summary screen. Select Appraisal to see which one of its IVs are the highest. In addition to this, there will be a silhouette (if players have not yet registered them) of either Hitmonchan, Hitmonlee, or Hitmontop near Evolve. If players want Hitmontop but their Tyrogue's best IV is its Attack, then they should refrain from evolving it and save the Candies for the next Tyrogue.
