Salamander is a Koolasuchus. He was Link's fourteenth creature.
His card winded up in Japan, and activated when a boat knocked open the Card Capsule. He was seen by some locals before encountering Team Monster. He battled Chomp and easily lost. He was later revealed to be a 4 on the Power Scale.
Sometime after Tusky's defeat, the Ocean Panic card winded up in his Card Capsule, and was activated along with him. After his defeat, the card blew away, thus he lost the ability to use this Move.
The seventh copy of the Aqua Javelin Move Card was in his Card Capsule, and activated along with him.
The ninth copy of the Shockwave Move Card was in his Card Capsule, and activated along with him.
The sixth copy of the Hydro Cutter Move Card was in his Card Capsule, and activated along with him.
He had never won a battle.
While some creatures in Monsters King are oversized, Salamander is one of the most drastic, over twice the size of normal Koolasuchus, and looking much more like a giant salamander than a real-life Koolasuchus.
