John Blacksad is the main protagonist of the Blacksad comic series. Like other hardboiled detectives, Blacksad narrates his stories, adding cynical commentary on the evils of the world around him. Unlucky in love, he never seems to be able to form a lasting relationship, often due to circumstances beyond his control. He usually wears a dark suit and trench coat, and uses the alias John H. Blackmore on several fake IDs, including debt collector, FBI agent and customs officer.
Blacksad made an appearance in the Mr. /co/ 2020 tournament, being sent to investigate the disappearances of multiple Mr. /co/ contestants. While he didn't make it past the Qualifiers, he managed to evade capture from the Egyptians.
Blacksad would also make an appearance in the 2020 Tag Team Tournament, with Weekly at his side. While they were able to make it past Qualifiers at that time, they didn't go very far.
