Masuka, Dexter's hilariously inappropriate lab colleague, is one of those characters who just sticks with you. He appeared in a whopping 96 episodes out of 'Dexter''s 96-episode run, which means he was there for pretty much the entire ride. From his cringe-worthy jokes to his oddly endearing loyalty, Masuka became a staple of the show's dark humor.
What's wild is how he managed to stay relevant even when the plot got super heavy. Whether Dexter was dealing with family drama or hunting serial killers, Masuka was there in the background, cracking jokes about blood spatter. It's a testament to how well the character balanced the show's tone—without him, 'Dexter' might've felt way grimmer.
