Just encountered it as though it was a Strong Monster.

- Interesting. I can tell you with certainty that it definitely was a boss monster, and not very long ago. Aboveground, meetable after mini-quests or with activatables. I think there are two explanations, and I don't know which is more likely: it's no longer a boss, or it made its way into the game as both a boss and a strong monster.
