Some say that Luxray or Entei are the kings of beasts, and others give that title to Nidoking or Kingler. All these pokemon have some claim to the kingship, but they are not the only ones, for the rare male Kangaskhan are equally renowned as a powerful leader of pokemon.

They are called Kangaskhagan by some, khan of khans, and their harems (owing to the rarity of males of the species) are even larger than those of the Mongol Emperors. They are quarrelsome beasts, willing to take vast hordes of pokemon to "war" (or at least to battle) over a female kangaskhan or even a held item. They are magnamious towards those who surrender or those they defeat easily, but will punch someone into a pancake (human or pokemon alike) if they resist for too long. They are often compared to Tyranitar in their fighting style, the influence they wield among other pokemon, and the sheer strength of their attacks; some poorly-informed trainers have even mistaken Tyranitar for male Kangaskhan, or speculated that a Miltank/Tauros like relationship exists between the species. (In reality, there are female Tyranitar; they just look a great deal like the male ones.)

They are generally considered to be too dangerous to train, for even ghosts fear them, and are often regarded as a symbol of the wilderness. Although there are no credible reports of one being captured per se, there have been numerous reports of a male Kangaskhan in the company of one Erma, head of the Pokemon Ranger Union. It is not her pokemon, but a wild ally which works with her to protect the peace of Almia.
