In guardians of the Galaxy 2, Yondu reveals to Rocket that when he was young he was sold to Kree slavers. However, as far I can recall from the dialogue, it's never explicitly stated that Yondu is a Kree.

From what I can remember, most characters in the Guardians movies that are blue like Yondu have tended to be Kree, including Ronan and the Kree (admiral, captain, whatever) that Nova Prime talked to.

So, is Yondu a Kree?
