Like the other Cyclone bosses, Zyclone has an extremely fast attack rate, massive health, and unbeatable DPS. However, it is also a Zombie type, which means that it can respawn after being killed. Unlike other Zombies, however, it can revive an infinite amount of times! Like Metal Cyclone, Divine Cyclone and Super Cosmic Cyclone, it is not counted as a Floating enemy, so most anti-Floatings won't help here. Unlike most other Zombies, it does not have the 'burrow into the ground' ability and cannot sneak behind cats unless it is killed. This is probably due to the Zyclone being such a powerful enemy, and if it did sneak, it would be impossible to win, because of how Zombies take no damage while in the ground.
The spirits of those defeated by the Battle Cats have gathered into a vengeful storm. How can you defeat a whirlwind that is already dead?
The vengeful souls of those who died in battle coalesced into this great vortex.
By absorbing the life force of all who get near, it can revive itself many times.
Perhaps you could prevent it from reviving with the power of zombie killers...
It is suggested to use ranged attackers and meatshields, just like against the other Cyclones. However, since this cyclone can respawn, it is advised to either bring Zombie Killers, or to have cats that move fast, e.g. Awakened Bahamut, Immortal Yukimura, etc, to go behind the Zyclone while it is respawning.
If you have Iron Legion units, this enemy is a piece of cake. Stall with Gato Amigo, Jiangshi, Crazed Wall, and Wall Cat (if some of these are/almost hypermaxed, you can try use only 3 to save space for damage dealers). If you don't have Iron Legion cats, substitute with Glorious Amaterasu and/or Mighty Lord Gao. Lumbercat is strongly recommended. Use Awakened Bahamut or Immortal Yukimura to finish the base when Zyclone is dead and no other enemies are in the way (close to where Zyclone died). Fill the rest of the space with ranged attackers and any strong Uber Rares (Holy Valkyrie is optional). Rich Cat and Sniper the Cat are strongly recommended (if you ran out of Sniper Cats, use Sniper The Heavy to substitute if you have)
Time between attacks
120 (area attack)
Revives with 100% HP after being defeated for 120f (∞ times)
*In each stage, there is strength magnification, the value of health and attack power varies due to this value.
*Time between attacks is the time of the attack from the motion end until the next attack motion start.
This is one of the first Zombie enemies in the game that can revive more than 1 time.
