Athena is a pink Celestial that was added on May 26th, 2021, along with the other Celestials.
Athena is made up of three separate shells, each with their own weapons. The bottom shell spins counter to the other two shells. The bottom layer, a nonagon, has a Giga Trap launcher on each side. The middle layer, a heptagon, has a crasher spawner on each side that spawns giant crashers. The top layer, a pentagon, has a Quintuplet auto-turret on each side.
Athena's mega crashers are slightly smaller than those of Zaphkiel, but they are a little faster and have much longer range, sometimes chasing players up to half the map's distance. The Quintuplet turrets spew dozens of bullets per second, and can easily shred an unprepared army of tanks. The Quintuplet bullets are also very fast, so outrunning and dodging them can be difficult for some tanks.
