Pokémon typically cannot speak directly to humans. Their dialogue is often limited to their own names and the occasional onomatopoeia. However, some Pokémon have managed to break through that language barrier to let people know exactly what they’re trying to convey.
It’s not just about Mauzi’s ability to speak after extensive training. Pokémon have found all sorts of ways for humans to hear and understand them. Here are some prime examples of such Pokémon that have managed to “talk” to humans.
Mewtwo and other legendary Pokémon use telepathy
Mewtwo doesn’t speak per se, but it can communicate in words humans can understand. It does this by telepathically projecting its thoughts to anyone within range. Technically, Santa Clause’s Lapras was the first Pokemon to use this form of communication, but Mewtwo was the one that popularized it. It became the primary language of most Legendary and Mythical Pokémon in the films, as well as some other prominent Pokémon such as Lucario and Zorua. Although it makes sense for a Psychic-type Pokémon like Mewtwo to communicate telepathically, it’s unclear why other types of Legendary Pokémon can do so.
Pokémon like Beheeyem can speak directly through Meowth
This is a form of cheating, but a Pokemon can communicate with humans using someone who already speaks the language, like Meowth. Some of them can also possess a translator’s body in order to “speak” through them. This method was originally used by a mutated Tentacruel, but Meowth was also possessed by a Ghastly and Haunter, a Deoxys, and a group of Beheeyem. A yamask was similarly able to talk to humans by possessing cilan. This method of communication indicates that all Pokémon have at least a passing understanding of human language, limited only by their own ability to speak it.
Ninetales and Zoroark speak through human illusions
Some Pokémon were able to replicate human speech through illusions. For example, from episode 232, “Just Waiting on a Friend”, a Ninetails created the illusion of a girl named Lokoko, who fooled Ash and his friends for a while. Even after the trick was figured out, the Nine-Tails continued to use the illusion to talk to them.
A similar situation arose Black and white Episode 127, “The Island of Illusions!” Here, a Zoroark was able to create an illusion of Nurse Joy that was convincing enough to fool the main characters. In either case, these indicate Pokémon’s understanding of human behavior as well as human speech.
Manaphy can repeat a limited number of words
It’s rare, but other Pokemon besides Meowth managed to learn human speech. The Manaphy from Pokémon Ranger and the Temple of the Sea is a prime example of this. Even as a newborn Pokémon, it quickly learned what lines it was given. At the end of the film, it might even say full sentences like “I love you mom.”
Of course, the range of Manaphy’s dialogue is strictly limited. Additionally, it probably won’t learn new dialogue once it’s released into the wild. Regardless that it has learned something is impressive.
Rotom can talk through certain devices
A Rotom can use human speech perfectly when attached to the appropriate device. This trend started in Pokémon the Series TV: Sun and Moon, where Ash was regularly pursued by a Rotom Pokédex. Other Rotom have been shown to master human speech by entering phones and drones.
In these cases, the Rotom are more apt to say lines expected of the device they possessed. For example, if they own a Pokédex, most of their dialogue revolves around Pokémon facts. Regardless, they are perfectly capable of using human speech.
