Look away if you don’t want to see the spoiler! (Not official) (It’s just a prediction)

Full Abilities breakdown: (updating slowly bear with me)

PASSIVE : Regenerator - When a Pokémon does not take damage from the other team’s pokémon for a certain period of time, it’s HP gradually recovers.

BASIC ATTACK / BOOSTED ATTACK : The third normal attack becomes a reinforced attack that cleaves flames, increases the damage dealt, and recovers HP. The amount of HP recovered increases if the enhanced attack hits more than one Pokémon.

INITIAL SKILL 1  Safeguard : Protects you with its magical power and reduces the damage you take next. When damage is reduced, its movement speed is increased for a short time.

INITIAL SKILL 2 Tailwind : Creates a vortex of wind in the specified direction, damaging the opponent’s pokémon. The vortex remains for a while, and Pokémon on your side that go in the direction of the wind will move faster, while Pokémon on your side that go in the opposite direction will move slower.

SKILL 1 first option Fly & Fly+ : Increases the height of the Pokémon’s flight, allows it to ignore walls, and increases its movement speed and attack power. The next three normal attacks following the use of this move become enhanced attacks, allowing the attacker to use normal attacks and moves while moving. Using this move again causes it to descend to the ground with great force, damaging surrounding Pokémon.

SKILL 1 second option Fire Spin & Fire Spin+ : Creates a flaming vortex centered on you, damaging and slowing down your opponent’s Pokémon and causing allied Pokémon inside the vortex to take some of the damage instead. At the start of this move, the Pokémon gains the Shield effect, and the move ends when the Shield effect disappears. If a certain amount of time elapses while the Shield effect is still in effect, or if this move is used again, a heat wave is released around the Pokémon, damaging the opponent’s Pokémon. The more damage it takes while the effect lasts, the more damage it does.

SKILL 2 first option Flamethrower & Flamethrower+ : Sprays out a burst of flames in the specified direction, damaging the opponent’s Pokémon and lowering its Attack and Special Attack. The longer the flame is out, the longer the wait time for this move. If you keep hitting the opponent’s Pokémon with this move, it will be burned for a certain period of time and its movement speed will be reduced. When a burned Pokémon moves, a trail of flames is left behind.

SKILL 2 second option Sky Attack & Sky Attack+ : The Godbird spreads its wings and charges, then turns around and returns to its original position. It damages any Pokémon it hits and burns the ground it passes through for a while. The burning ground damages and slows the opponent’s Pokémon. If the attacker uses this move again or uses another move, the assault stops on the spot.

UNITE MOVE Rainbow Flame of Resurrection : When a Pokémon is KO’d, it will leave a feather mark for a short while. After spreading its wings wide, it expends all of its Eos Energy to heal the KO’d Pokémon and return it to the battlefield from the position of the feather mark. The more Eos Energy it consumes, the more allied Pokémon it can return to battle.

TL/DR : passive is free leftovers, boosted attack regens HP, Fly is a mixture of Charizards unite move and Talonflames fly, Unite is free res to all four teamates if you have enough Eos Energy and they’re within range.
