Niantic has added Ditto in Pokemon Go for a couple of days already and fans are hyped to finally witness the most-awaited mimic Pokemon. However, Pokemon Go players are wondering if will there be another Pokemon to be released separately in the following generations, knowing that a Gen 2 update is constantly rumored to be the next major update to arrive.

According to the report from Otakukart, there are several Pokemon in the future generations that could be introduced similar to Ditto. Report said that these Pokemon would perhaps give Niantic the most trouble once introducing them to Pokemon Go.

First on the list is Smeargle. This Pokemon is known to contribute more trouble to Niantic compared to Ditto as it has the ability to permanently copy the abilities of its foes during battle. In order to make that happen, Niantic require some extra codes to implement this type of ability.

Next Pokemon that might be difficult to introduce is Unown. This ancient Pokemon will need a special handling when it comes with PokeDex entries. As reported, it will require players to still track of all Unown variants after the first catch.

Third on the list is Shedinja. It has a unique ability that will not take any damage unless it is super effective. As a result, this ghost Pokemon would be annoying enough as a gym defender. Fourth on the list is Slacking. Slacking is known as the less cool version of Snorlax. It possesses great strength, however, it lazes around a lot which would be a challenge for Niantic to introduce Slacking to Pokemon Go.

Finally, the Pokemon that is included on the list is Zoroark. It is similar to Ditto but nowhere near as strong. It was reported that Zoroark can cast illusions and mimic Pokemon's appearance. However, it will be dispelled once the Pokemon is struck.

These 5 Pokemon will most likely give Niantic trouble on integrating them to the game. As a result, introducing them separately like Ditto would be a possible scenario.
