Beyond that, he also has Yondu’s Yaka arrow, which could be a massive asset to The Avengers and The Guardians if he has been practicing how to control it.
If Kraglin did survive the events of Avengers: Infinity War, there’s still a hope that he could become a principal ally in the continuation of the Infinity War story when Avengers 4 premieres.
(It probably would have helped out a lot during that massive Wakanda scene.)
James Gunn could also simply be alluding to what he has planned for the character in the next Guardians of the Galaxy-based adventure, so we’ll have to wait and see how that all pans out.
