1. Black Dragon. Designed in a Western style, or in the style of evil dragons from D&D. Immune to magic, breathes fire (possibly setting things on fire), has the most powerful stats in the game.
2. Golden (mythical) Dragon. Designed in a Western style, or in the style of evil dragons from D&D. Magic mirror, Caster, acid breath (with a poisoning effect), slightly weaker stats than the black dragon.
3. Lava Dragon. Elemental, immune to fire, breathes fire, does not fly, tougher and darker in color than the black dragon, but deals less damage.
4. Azure Dragon. Designed in a Chinese style. Immune to cold, freezing breath (effect similar to the Deep Freeze spell from Heroes 5), and something else.
I also want a Dark Dragon that attacks with darkness and lives in the dungeon, a Dragon of Earth (Western, evil D&D-style dragon) that buries enemies with earth and stuns them on attack, and that can burrow underground and emerge on the battlefield, and a Dragon of Air that attacks quickly and is ethereal, and if it hits, it splits into two smaller dragons. This one could also be in the evil D&D style, half-Western.
Oh yeah, nin hao! lol. Konnichiwa! xDxDxD
