The punch of a Tyrogue is nearly as strong as a Hitmonchan's, and even more remarkable is how effortlessly they appear to do it. Tyrogue do not sweat, pant, or breathe heavily, and to the untrained observer their fighting is as much a painful mockery of their opponents as a serious attempt to win. In reality, Tyrogue push themselves to their limits, and are equally known for falling asleep in the middle of combat. Sleep, however, only slows them down, as their feet dodge attacks with footwork rivaling a Hitmonlee's.
The reason they do this is because to Tyrogue, this is the essence of what it means to be a man. Tyrogue, like their evolutions, are deeply steeped in an ideal form of masculinity, which they identify with unflinching courage and enormous power, and stamina. There are no female Tyrogue, nor is there a counterpart species as with Miltank and Nidorina; those few born with the capacity to lay eggs switch their gender not like Azurill by random chance during in evolution, but by pure willpower soon after birth.
Given that the same gender cannot breed, it is unclear how Tyrogue continue to be born. To be sure, Ditto likely play a role – they must in captivity, and unless their mothers are yet to be discovered, so do they in the wild. But what do they turn into? What sort of strange creatures were once Tyrogue's mothers? What form do Ditto take to mate and lay their eggs? And if a Tyrogue was born female and did not see all that is good in the world in a single gender, what sort of pokemon would they become after evolution?
Perhaps someday, science will shine its light on this fascinating pokemon and the mystery of its birth.
