Gasnine take pleasure in playing malicious tricks on people. Acting benevolent, they allow people to clamber onto their back and take them for rides across the sky before abruptly turning intangible, allowing their passenger to fall to the ground.
This fleet-footed Pokémon is said to run over 6,200 miles in a single day and night. When exposed to a strong wind, a Gasnine's gaseous body quickly dwindles away.
