KD6-3.7, also known as K and Joe, is a Replicant Blade Runner of the "new batch" from 2049, engineered to be less rebellious than the original Replicants. Being a replicant from the new batch, he is trained to show little to no emotion as a Blade Runner in order to complete tasks that are at times questionable and any opposition would result in his death. As a result, K presents himself as stoic and rather serious and rarely ever smiles, he is also thorough in completing his tasks.
