^ Diablos and Gravios are capable to fly a little bit, even in-game (Gravios with the slam Attack, and both of them when they need to reach higher areas or whey they need to escape from a Pitfall Trap).

And speaking of Primatius, don't forget about Bullfango, which has been reclassified once and the category has been renamed twice.

Bullfango: Herbivore (1st Gen) > Primatius (2nd Gen) > Pelagus (MHFU) > Fanged Beast (3rd Gen onwards)... lol
