Luxray seek battle with their enemies as ferociously as Zangoose and Seviper, but because both pokemon involved are nocturnal, stealthy, and black in color, their battle has elicited far less attention, and the legends surrounding their rivalry from times of old risk being forgotten. And this is a shame, for the fury with which Luxray's ancestors hunted Mightyena for generations has given these pokemon both remarkable eyesight and a reputation as kings of the jungle.
Man, despite his stories of royal usurpation and eternal pokemon wars, is a latecomer to this rivalry. Its origins lie in an age-old struggle between packs of these two pokemon to dominate the food chain; a struggle which appears to have started nearly as early as their ancestors diverged into separate lines of pokemon. Mightyena aid hunters because they feared the Luxray and wanted an ally. Luxray choose to spare a select few Buneary and Bidoof in return for their aid in tracking passing Mightyena. Even Luxray's Noctowl-like eyesight, which allows them to spot nearly any nearby pokemon at rest, is believed to have developed first to target Mightyena, and only later their actual prey. Luxray walk so silently that they are usually only exposed to their foes (and in recent times, human hunters) when they attack with their terrifying roar or deadly blasts of lightning.
Today, even wild Luxray can be tamed in pokeballs, and the position of men in the Mightyena-Luxray rivalry has shifted to support of whichever one that particular person trains. Yet both of these species are pack pokemon with fairly similar behavior, and when separated from their own alpha pokemon and forced to call a human their leader, their rivalry can swiftly dissipate. Today, the Luxray no longer resist, and man is the unchallenged king of the jungle.
