Mortynight Run", Krombopulos Michael is introduced as
Rick Sanchez's "best customer", a
hitman who buys an anti-matter handgun from him for use in an upcoming assassination of his. While meeting Rick at a garage to purchase the gun, Michael introduces himself to Rick's grandson
Morty, giving him a
business card (listing his contact information, social media accounts, and "#KMichaelKills"), who expresses disapproval at Michael's open love of killing and general lack of morals. Later after breaking into the facility used to hold his target, a gaseous being, kissing a photo of his wife beforehand for luck, he is accidentally crushed to death by Morty, who crashes Rick's ship into him after stealing it, before completing his mission for him.
