Hello, I'm an expert in comic book lore and superhero narratives. Let's dive into the relationship between Deadpool and Deathstroke.

**Deadpool and Deathstroke are not brothers.** They are two distinct characters from different comic book universes. Deadpool, whose real name is Wade Wilson, is a character from Marvel Comics, known for his humor, regenerative healing factor, and tendency to break the fourth wall. Deathstroke, on the other hand, is Slade Wilson, a character from DC Comics, who is also known for his exceptional combat skills, strategic mind, and a suit that grants him enhanced strength and agility.

While both characters share the last name "Wilson" and have similar abilities, they are not related in the traditional sense. The similarity in their backgrounds is likely a nod to the fact that they are both antiheroes with a military past, but they operate in separate universes and have their own unique storylines and character developments.
