==Strategy==
Please note that you are strongly recommended to collect most or even all Anti-Starred Alien Treasures from Cats of the Cosmos at this point since the Starred Aliens here have extremely high buffs. Otherwise, they will be very hard for an average player to handle.
The strategy in this stage is to focus the backliner enemies as much as possible before killing the Primeval Cyclone. LD units such as Fiend Cat, Golfer Cat, and Awakened Mina, along with Wave Attack units like Manic Macho Legs and Talented Pizza Cat can accomplish this task. Depending on how you approach this stage, a Fiend Cat with Target Angel Talent can make this stage easier or harder. Talented Rodeo Cat can easily help keep the Primeval Cyclone from destroying your LD stack. A general lineup may consist of 3 meatshields, Rodeo Cat, and 6 LD/Wave Attack units. It may help to replace some of the LD/Wave Attack units with long-ranged units in case the Primeval Cyclone dies before you can finish off the rest of the backliner enemies.
Angels and Starred Aliens appear as support, so if you have any remaining slots, you may add in anti-Angels and anti-Aliens if you want. Do note that this is not necessary and only add them if you have nothing else to add to your Cat army.
