In the flashback in Glory Blaze, it is revealed that Paul previously caught a Ninjask; however, it is not seen outside of the flashback and it is unknown if he still has it.
Ninjask moves around at such a high speed that it cannot be seen, even while its crying can be clearly heard. For that reason, this Pokémon was long believed to be invisible.
If Ninjask is not trained properly, it will refuse to obey the Trainer and cry loudly continuously. Because of this quality, this Pokémon is said to be one that puts the Trainer's abilities to the test.
Ninjask have the second highest speed of any Pokémon in the games. They are surpassed only by the Speed Forme of Deoxys. With its ability, Speed Boost, and proper EV training in Speed, it is able to be the fastest of all Pokémon.
