It has an enormous range of 650, but can't hit close units, giving it a major flaw if your units can get close enough. However, it is virtually impossible to get close enough, because its attack rate is insanely fast compared to other Long Distance enemies.
A Category-5 storm that grew massive by consuming lesser cyclones. Repels threats from uber long distance. Meteoroloigists say getting near its eye disables its knockback.
You can kill it easily by stacking Sadako Cat and A. Bahamut Cat. You need to weaken the Cyclone, then release A. Bahamut Cat, as demonstrated here. If you make the Cyclone stay next to the enemy base, Bahamut will kill it without being damaged due to the knockbacks that the Cyclone will receive.
If sufficiently levelled, and with a Unit Defense UP Combo, you can use Titan Cat and Crazed Titan Cat due to their high HP. Divine Kai can also DESTROY this enemy, even at level 30. A Perfect Cyclone without support canbe soloed by Divine Kai (like in Oncoming Storm).
Be warned that, although this Cyclone has a minimum range, it can hit the Cat Base at point blank range just fine.
