Thundurus's name is a misspelling of the word "thunderous". The choosing of this name is possibly due to the end of its name having to match Landorus and Tornadus' and when it uses lightning, thunder accompanies it due to hot air particles brushing against cold.
Despite Thundurus being the Bolt Strike Pokémon, he cannot learn the move Bolt Strike.
Thundurus is the only one of the Djinn trio to not have his Therian forme resemble a creature in reality (Landorus looks like a cat, Tornadus looks like a bird).
Thundurus and the rest of the Kami trio will have 3DS and AR searcher app exclusive forms in Pokemon Black 2 and Pokemon White 2, called "Therian Formes", while their current forms are called "Incarnation Forms".
While Thundurus has a gender, it still cannot breed because it is in the undiscovered egg group.
