An easily irritated, generally annoyed, and hard to get-along-with personality. He likely has a sense of overblown pride in his own skills. He is likely the best pilot on the entire Star Fox team though, so at the very least he’s earned his belief in himself. Falco’s voice actor will need to be able to convincingly pull off sounding irritated and angry, as Falco frequently becomes irritated and angry. Of all the characters across multiple games Falco has been portrayed the most consistently, so looking into his performances from any of the games will probably get his character across. I see a tendency of voice actors to really overblow his Brooklyn accent, however. I would prefer that Falco does not have such a strong accent, as I really do not hear it much at all in the actual Star Fox games. I am open to being convinced otherwise, however.
