In battle, the Czar Dragon attacks with many fire-related moves such as Flame Wall. Despite being made of fire, the Czar Dragon is capable of using the deadly Water Blast move. After the Czar Dragon is defeated, it will transform into Zombone.
The Czar Dragon is weak to ice-related moves so Mallow's Snowy will come in handy in this fight. Mario should also avoid using his fire techniques and stick to Jump techniques while Princess Toadstool heals.
