Invasion of Poultrio

RUNS ON the 1st, 2nd, 15th & 16th of every month SEE THE CALENDAR →
The newest Great Advent, added in Version 15.2, running on the 1st, 2nd, 15th and 16th. Unusually, it has three Merciless stages and one Brutal rather than the usual one Deadly. The Swan Song drops Paperboy Cat at 100%.
Poultrio carries three traits at once — Red, Dark and Aku — with 3,600,000 HP, speed 60 and twenty knockbacks. It hits three times for 7,777 every 21 frames through an Omni Strike covering -420 to 390, sits behind a 60,000 HP Aku Shield that regenerates to full, has a 15% chance to trigger an Explosion at 290 range, and is a Base Destroyer dealing four times damage to your base.
Being Red, Dark and Aku simultaneously means very few anti-trait units miss it — but it also means almost nothing resists it.
