|First appearance||The Sacred Orb|
Megarus is an imposing battler and always brawls to the end. His many fins make him super fast in the water and difficult to catch in a brawl. Megarus' exoskeleton shell is strong and durable. His mouth contains a thousand teeth that rip through the toughest armor.
In Infiltrated, they were seen again and were defeated by Akwimos.
In episode 8, several Aquos Megaruses were seen jumping out of water in New Vestroia.
