One of the most annoying Cyclones, requiring a lot of Critical Hits to defeat. It is the slowest Cyclone, though in return its stage length is much shorter. Anti-Metal cats obtained from the other Cyclone stages (Clockwork Cat is optional though) are almost required to take down the Metal Cyclone, along with Crazed Whale Cat, Island Cat, and cheap meatshield cats. If you have them, Berserker Cat will be able to deal massive damage to it and Tesalan Pasalan can annihilate this Cyclone with one Critical Hit. Take a look at Anti-Metal Cats for a list of all the anti-metal units.
Unlike some of the other Cyclones, it is not considered a [[:Category:Floating Enemies]|Floating]] enemy, so anti-Floating units won't help much against it.
