This enemy has extremely long range and mostly high stats. She has a somewhat long attack rate and attack animation, she also has a chance to weaken your cats to 10% of their normal attack power! Fortunately, she has slow speed and surprisingly, a high knockback count. When you first encounter her, it is highly recommended to collect ALLanti-unstarred Alien Treasures up to that point so she is at a beatable difficulty level for the average player.
Not many units can outrange Cli-One, so focus on units that can survive her attacks. Overall, you should treat Cli-One like an upgraded, more advanced version of Nyandam.
*Above stats are with 600% anti-Unstarred Alien Treasures; see below for stats without all Treasures.
*Anti-Unstarred Alien Treasures include Aqua Crystal and Plasma Crystal.
This enemy is based on sea angels, sometimes called "cliones".
Her appearance and attack animation may also be a reference to the Angels in Neon Genesis Evangelion. The description tends to be a reference of the moon in the Rebuild of Evangelion's movies, where a part of the plot takes place.
When opening her head to attack, her attack animation is similar to the aliens in the sci-fi horror manga Parasyte.
