Snifit on Stilts said:Gyarados is water/flying because in gen 1 the only dragon move did a set amount of damage, thus making gyarados have nothing that does super effective damage.
Likewise, Gyarados would be overpowered for not having a weakness. Kingdra is a Water/Dragon-type, but at least the 2nd generation introduced Dragon-type moves that do not deal set damage, making it less lethal.
