I'm having difficulty coming up with my abilities...I guess its trying to incorporate the chocobo into everything any thoughts?
Chocobo knights have lances besides your abilities are in speed and that powerful moment of impact as a strike with the lance. You've got tactics at your disposal instead of a large array of tools and weapons, that being said it's not easy coming up with ideas beyond Strike. So here's some suggestions.
Stun: While riding the chocobo you are able to use the ability "Feather Daze Dash" which is like sonic rush from Kingdom Hearts 1. When you hit a foe with this move it stuns them as your quick speed will have them in a daze. Sure it has damage but it's focused on confusing a foe.
Defense: While riding the chocoho you are able to use the ability "Dodge and Duck" which is a tactic where you alter your behavior, making movements more subtle instead of proclaiming your courageous motions for your enemy to predict, in a sense you wait for the foe to strike, analyze your environment then use the speed you posses as a tool to out maneuver foes, sometimes able to counter attacks.
Disable: While wielding the Lance you can impact a foe, or part of their clothing to a surface such as a wall to get them pinned down. Short sweet and simple until you reveal the "Finisher Deluxe" which consists of your chocobo moving real quick then slamming on that lance in the case that it's sticking in a foe's shoulder or stomach perhaps. Yeah it consists of mostly damage but the start if that Disabling Pin Down.
Enabler: Your chocobo releases some magic, casting Hastaga on the party while simultaneously casting Slowaga on foes. Sure it does both disabling and enabling but the primary feature here is the Hastage for your party.
Skill: military tactics, military survivalism, um experience in the wild, traveler's knowledge of geography, map making, biology, ranching, what ever makes sense for the character.
Now "strike" looks like the boring part of your character.
Edit: thank Fate/Zero for being a cool and inspiring action battle anime when it's not earning that rated MA with detestable characters.
