Dragons are the center of the mod
Everything in BDA depends on the dragons being worth caring about. If the dragons look wrong, behave wrong, or feel like normal Minecraft mobs with wings, the whole project fails.
V0.5 starts with three supported species: Night Fury, Deadly Nadder, and Gronckle. They are not just a list of mobs. Each one exists to prove a different side of the dragon system.
Night Fury
The Night Fury is the rarest and hardest dragon in V0.5. It is meant to be suspicious, intelligent, fast, and unforgiving if the player acts like a threat.
It detects players from far away, can smell them at closer range, reacts heavily to weapons and armor, and requires careful behavior before it becomes bondable. It is the dragon that has to sell the Toothless side of the project properly.
Deadly Nadder
The Deadly Nadder is more openly territorial. It is alert, sharp, and defensive, with a faster warning profile than the Gronckle but less paranoia than the Night Fury.
In V0.5 it gives the project a faster, spikier dragon identity and a strong middle point between the Night Fury and Gronckle.
Gronckle
The Gronckle is slower, heavier, and more tolerant. It is the easiest V0.5 dragon to approach and tame, which makes it important for players learning the system.
That does not mean it should feel low quality. It just fills a different role: heavy, stubborn, grounded, and easier to understand.
Wild dragons
Wild dragons spawn as adults. They roam, perch, stop to look around, react to hostile mobs, and handle players through the taming/threat system rather than instantly acting like loot.
Night Furies spawn alone in high terrain. Deadly Nadders spawn in smaller groups around Taiga and Meadow areas. Gronckles spawn in larger groups around mountain and Taiga-style terrain.
Tamed dragons
After taming, a dragon becomes owned by the player and switches into the post-tame systems: hunger, XP, levels, bond, commands, GUI, saddle, cargo, riding, combat, breeding, eggs, hatchlings, growth, and downed-state recovery.
That is what makes the dragon more than a mount. It becomes a long-term part of the player’s world.
