According to Pokémon early concepts, baby Kangaskhan were originally slated to be its own individual Pokémon. In addition, it was planned to have two possible evolution stages. If its mother Kangaskhan fainted a certain number of times, it would die and the baby Kangaskhan would evolve into a Cubone which could be supported by the fact that the head aesthetics of Kangaskhan is identical to that of the skull worn by Cubone and its successor stage, Marowak (which would have evolved into Kangaskhan). However, due to difficulties laying out how loop holes in how the events leading to the events, the idea was scrapped the last minute prior to the first games release.
It was originally planned to be a Rock-type, likely for the reason above.
Kangaskhan is the only Pokémon that appears as two individual Pokémon but are both labeled as one despite the fact that most of the later Pokémon have individual stages for baby forms.
Kangaskhan probably derived its name from the great Mongol leader, Genghis Khan.
Kangaskhan owns a storage shop in the mystery dungeon games.
The baby Kangaskhan in its pouch may be an unrecorded Pokémon that may be recorded in future Generations.
This Pokemon is a "missing link." Marowak would evolve to Kangaskhan, then the mother would die, letting the baby Kangaskhan evolve into Cubone. However, this evolution split between Marowak and Kangaskhan made MISSINGNO., the Glitch Pokemon.
