The "Salamangreat" monsters are based on fiery themed animals. And while the Main Deck members appear to be based on small and average-sized animals, the Extra Deck monsters are based on the largest and most majestic of the animal kingdom. Much like Yusaku's animal-based Cyberse monsters, "Salamangreats" are armored with a cyberspace design. They also have a hot-red tint spread over their bodies and are constantly emitting flames.
Salamangreat is a portmanteau of the words "Salamandra" and "Great". Their kanji (転生炎獣) translates as "Reincarnated Flame Beast", which is linked to the archetypes's style and philosophy. The members of this archetype are named after various, likely symbolic, fiery animals.
