Aniimo Open-World Boss System Omega bosses don’t spawn on a timer. There are 3 of them, one per region, and each stays inert until you finish a specific Journey quest. Waiting at the marker does nothing until that quest is done. Below: all 3, what unlocks each, and how they differ from the roaming Alpha tier.
Alpha bosses roam the open world and respawn on their own – no quest gate, cheaper to challenge. Omega bosses are a separate, quest-gated tier: a boss-danger marker that stays inert until you’ve completed the right Journey quest in that region, then costs double to fight and refreshes weekly instead of ambiently.
This is what the fight is for. 17 of the 20 world bosses unlock an evolution: that Aniimo will not evolve until you have beaten its boss, whatever else you have done.
Three, one per region. Each one stays inert until its own Journey quest is finished.

17 Alpha species roam the open world across 18 boss markers: no quest gate, 30 Primegy per attempt. Each card below shows the ground it stands on and the evolution its defeat unlocks. Two of them are not on the ground at all: Geoclaw and Minespine stand in caves, and their pins are the only two the game leaves off its own map and compass until the Branch's 120-Amber blessing, Earthwake Prayer, reveals the caves.

It is not a passive spawn: there is no ambient timer and no weather trigger. Waiting at the map marker, at any time of day, does nothing. Each one appears only once you finish a specific Journey quest in its region, the one named on its card above.
The encounter refreshes weekly once unlocked. Treat it as a weekly cooldown rather than a fixed day of the calendar.
All 3 cost 50 Primegy per attempt, double the 30 Primegy of an Alpha field boss.
Alpha bosses roam the open world and respawn on their own, no quest required, for 30 Primegy. Omega bosses are a separate, quest-gated tier: 3 of them, one per region, each behind its own unlock quest and costing 50 Primegy.
