How to beat it

A rewrite of the in-game help and of the prompts shown during the fight: no made-up strategy.

It raises a Storm Shield: deal enough damage to break it and the Alpha drops straight into the Weakened state.
Destroying that shield also interrupts the cast it is charging.

What holds for every Alpha and Omega

After Alpha and Omega Aniimo leave BREAK state, they enter BREAK Recovery state until their BREAK gauge fully recovers. While in BREAK or BREAK Recovery state, they take greatly increased damage.
Watch out! Warning areas will appear on the ground before the Alpha attacks. Make sure to dodge in advance!
There will be only one chance to catch an Alpha after defeating it. Switch to the most advanced Aniipod you have to catch!
