While Tornadus has a gender, it cannot breed because it is still a legendary.
In Pokemon Dream Radar, Tornadus appears as one of the legendary Pokemon of the game, but, unlike the rest of the Kami Trio, is encountered twice. The first time is when the player completes a research for the first time, where Tornadus appears to the player, but cannot be battled, as Tornadus flies away. The second time is when the player opens up the extension. This time, Tornadus is battleable.
It is one of three Pokémon that have Flying as one of its types but not have it as a secondary type. It shares this trait with Noibat and Noivern.
Of the three, Tornadus is the only one that has only one type.
Tornadus resembles a Djinn. Its Therian form resembles a bird.
Tornadus' name is a combination of the English words "tornado" and possibly the end of "Enceladus," who was a giant in Roman and Greek mythology.
