History
- It was first seen on July 23, 2025 around 10:35 CET, being the first boss to invade all Game Worlds at the same time (except Kalibra, which was offline due to technical problems).
- On August 13, 2025, Rejana posted that "the feedback had already been forwarded ... that a fixed spawn time is seen as problematic", but no changes were announced.
- On August 19, 2025, the patch gave it more HP, better armour, higher DPS and healing, and highly increased its Mitigation.
