The Red Dragon is a Boss Monster in Lost Kingdoms, appearing at the end of Mt. Jarndunn.
It later appears in Yalwog as a regular, yet powerful, enemy.
As a card Edit
The Red Dragon is one of the strongest Summon monsters in the game. It possess long range, good power and is cheap when compared to other monsters of a similar level.
The only set-back is that the Red Dragon has a fairly narrow range in a straight line, making agile enemies a pain.
