MISSION FILE / BOSS-08
Boss Order & Weaknesses
Regenesis has two separate four-boss weakness cycles, not one optimal 1–8 chain. Start each cycle by beating any one member with the X-Buster, then follow the weapon rewards.
Load your next target
Choose a boss you already defeated. The console rotates that cycle to the weapon you now own.

03 / GUIDE SCOPE
What this route does—and does not—claim
The v1.00.4 guide connects boss names, stages, weapon rewards and 2× weakness factors in one route matrix.
The easiest neutral starter depends on movesets and player skill. This database does not invent a universal “best first boss.”
