While many aspiring knights choose a traditional steed such as a chocobo, not every knight is so usual. Some choose instead to either forge a kinship or a shaky alliance with a creature far more scaled and dangerous.
The wyvern rider is an archetype of the chocobo knight class.
Wyvern Mount (Ex)
At 1st level, rather than bonding with a yellow chocobo, a wyvern rider makes a bond with a capricious, fearsome, but loyal young wyvern. The wyvern has statistics as follows, and is of the Dragon typing (using a D12 as its hit die, full BAB, all Good saves, 6+Int skills). The wyvern otherwise uses the Chocobo Knight’s mount companion table and counts as a chocobo mount for chocobo knight class features. The wyvern cannot speak, but can understand the rider’s first language (usually Common) and Draconic. The wyvern has magic item slots as an avian body type creature.

Fly (Clumsy; the wyvern can carry a rider while flying but its speed is reduced by half) AC: +3 Natural armor Attack: bite (1d8) (10ft reach), 2 wings* (1d4) Ability Scores: Str 17 Dex 14 Con 15 Int 4 Wis 8 Cha 12; Special Qualities: Darkvision 60ft, Scent, Immunity to Paralysis and Sleep
*These are secondary natural weapons.
Speed: 40 ft., 100 ft. Fly (Poor; the wyvern can carry a rider while flying) Attack: Bite (1d8) (10-ft.-reach), 2 wings* (1d4), Sting (1d6 plus Poison) (10ft reach) Ability Scores: +4 Str, +2 Dex, +2 Con.
Wyvern Poison (Ex): Sting, injury; save DC 10 + half the wyvern’s HD + the wyvern’s Constitution modifier; frequency 1/round for 6 rounds; effect 1d2 Con damage; cure 1 save
This ability alters chocobo mount.
Sky Strafe (Ex)
At 6th level, a wyvern rider’s wyvern mount gains Flyby Attack as a bonus feat, even if it would not meet its prerequisites. If it already possesses Flyby Attack, it can instead gain a combat feat of its choice for which it qualifies.
This ability replaces master feeder.
