By now, many hardcore Pokemon GO players may have completed the Special Research quest to catch Mew. However, others may still be struggling with some of the quest's more difficult objectives, like evolving a Magikarp into Gyarados. In order for players to avoid getting stuck in future Special Research quests, we've selected three Pokemon whose candy players may want to hoard.

Since the Special Research quest objectives seemed to revolve around Pokemon with unique abilities or evolution rules, it's a safe bet that future quests will be similar. With that in mind, there are three Pokemon currently available in Pokemon GO that seem to fit the bill, and all of them are from the third generation.

The two most obvious choices are Wailmer and Swablu. Like Magikarp, both Wailmer and Swablu require a whopping 400 candy to evolve to their next forms. Assuming the next Special Research quest has a task like the one to evolve Magikarp to Gyarados, it seems likely that evolving Wailmer, Swablu, or both could be a factor.

The third Pokemon that may seem less obvious is Feebas. Feebas requires 100 candy to evolve into Milotic, but it has a unique gimmick to its evolution that could play role in the next Special Research quest. In order to evolve Feebas into Milotic, players have to assign it as their buddy Pokemon and walk a total of 20km with it. It may be smart for players to prepare a Feebas for evolution and keep it in reserve just in case a future Special Research quest demands it.

Of course, it's possible that the next Special Research quest will have objectives that are completely different than those featured in the first one. After all, Feebas, Swablu, and Wailmer are all third generation Pokemon, whereas the second mythical Pokemon is Celebi from gen 2.

Even though Celebi is the second mythical Pokemon added to the franchise, that doesn't necessarily mean it will be the second mythical Pokemon in Pokemon GO. Datamining efforts have already found evidence that third generation mythical Pokemon Deoxys will be added to the game, so perhaps it will be the next mythical Pokemon instead.

Pokemon GO is available now for iOS and Android mobile devices.
