Aniimo Alpha Annihilator achievement needs five Alpha/Omega defeats. Build a list of accessible bosses and check the counter after wins. Five successful captures are not the stated requirement.
Five early candidates
| Target | Region | Route note |
|---|---|---|
| Alpha Turbo | Nimbus Fields | Two-Nimbi floating-phase route. |
| Alpha Irisal | Sea of Flowers | The roadmap encounters it during Fragrant Colors. |
| Alpha Stellarys | Forest of Falling Stars | Check the Alpha marker, not a normal wild Stellarys. |
| Alpha Scorchhowl | Beast Fang Ridge | Read its current encounter level before committing. |
| Alpha Glynsera | Beast Fang Ridge | October 30 fixes its unintended battle-long Super Armor. |
This is an editorial checklist of published targets, not a benchmarked fastest loop. Your progression and party determine the sensible next fight. An available Omega fits the other named category; none is mandatory merely because the checklist lists Alphas.
Note your count before a fight. After the victory result, check for an increment and log the boss. Keep captures, spending and reward claims in separate columns. Without a visible counter, record completed fights rather than assumed credit.
Single source: broad roadmaps agree, but independent current observations of repeats, guest credit, reward claims and synchronization remain missing. Do not spend resources on repeated fights without checking what registered. No in-game testing or numeric time/difficulty promise.
