Donkey Kong

Donkey Kong was a Kong who notably ate bananas and said "Okay".

Birth
It is unknown how Donkey Kong was created. It is assumed Cranky Kong did several satanic rituals to create him.

Sometime after creation, he became the first member of the DK Crew.

Murder trial
Donkey Kong stood trial for the murder of Cranky Kong in February 1995, and was convicted October 1995. He was given a short 2 year sentence due to the "Frankenstein's monster" legal defence, Cranky's overwhelming unpopularity, and on the agreement that he would undergo anger management counselling. Donkey Kong was let out on good behaviour 2 months into his sentence, this was likely done in reaction to mounting political pressures calling for Donkey Kong's return to active service during the Great Ape War.
