Thundurus has often been called the assassin of the heavens, for the lightning bolts he hurls are a frequent and deadly instrument of his wrath. Although most bolts he hurls in thunderstorms are mere target practice, aimed at the highest object he can find (including the occasional hapless human or pokemon), he is more than willing to chase down and slay any individual who has angered the gods.
Although there are many steps which desperate individuals have taken to avoid Thundurus' wrath, the only reliable way to do so is to avoid performing acts of great sacrilege to draw his attention in the first place. Motor vehicles and other insulated structures can protect their occupants from lightning, as can most modern buildings, but these barriers can not prevent Thundurus from spitting ferocious winds to destroy wherever their victims hide; these winds often kills their targets with spinning debris without wasting a thunderbolt. Some pokemon can absorb electric attacks but most flee in terror, and the few who stay struggle to shield their hell-bound trainers from deadly winds or blasts of non-electric energy. Nor is it possible to outlast Thundurus, for although human endurance can escape many mortal wild pokemon, it has nothing on the tenacity of a god.
There are legends which describe villains so powerful they defeated Thundurus in battle, and their evil deeds are often overlooked in modern versions of the tale. This is because Thundurus is a devastating god who kills many by target practice in addition to those who have earned its wrath, and at best causes large storms which fry electrical equipment and make sleeping impossible. It has therefore become re-imagined as a demon, not an executioner; conversely, those who defy it have become folk heroes, despite their massive, disgusting crimes.
