Zombot Dark Dragon

Zombot Dark Dragon is the boss of the Dark Ages in Plants vs. Zombies 2: It's About Time. Unlike its previous predecessors, it is in a different form of Zombot which is a machine that is designed to be similar to a dragon. The Zombot Dark Dragon is the 11th zombie to be encountered at the last night of Dark Ages. It summons all zombies excluding the Peasant Flag Zombie and Zombie King. It can be stopped by the Magnet-shroom's Plant Food Upgrade.

Almanac Entry
TOUGHNESS: Undying

SPEED: Hungry

The desolator of all, from dark times.

Damage: fire breathing attacks destroy plants

Special: lobbed fireballs can hatch Imp Dragon Zombies

With a rumble of destruction, Dr. Zomboss forged his Dark Dragon in the heart of a volcano. Then he tempered the beast in the chilled waters of Doom Lake. Finally he fed its furnace with coal from the Mines of Morbidity. And the paint job - that was done by Carl.

Trivia

 * Unlike the first four Zombots, this one is not a one eyed, four legged robot, although its eyes look similar to the other Zombots' (which are yellow with a black pupil). After it is defeated, one of the Zombot's eyes fall off as metal parts can be seen. This shows that it is a robot, not biological lifeform. However, it is unknown if this one is four-legged or not. It shares this trait with the Zombot Sharktronic Sub.
 * It is the first Zombot to be based on an animal. The second is the Zombot Sharktronic Sub.
 * It is the first zombie and Zombot to lose an eye when defeated.
 * It is the second Zombot having Dr. Zomboss dressing up, the first being Zombot Plank Walker. In the Zombot Plank Walker, he wears the same only to include the eyepatch. Here, he dons a full Gladiator armor.
 * Dr. Zomboss' veins are shown through his helmet.
 * There is a cross tattoo or scar on the Zombot's face.
 * Dr. Zomboss is dressed up like a Roman gladiator since Rome fell just before the Dark Ages but the East Roman Empire (Byzantine Empire), survived until 1453, which was time when the Dark Ages started fading away into the Renaissance.
 * Its full body is only shown when it flies in. However, it is only a shadow of it.
 * This is the first Zomboss battle that has a premium plant and a plant that's not from the world it is the boss of in it (the Pea-nut and Kernel-pult respectively).
 * It summons zombies in a different manner than the first four Zombots. In the first four battles, zombies are summoned out of a portal inside the Zombot's mouth, by slowly transforming first from a white silhouette. The Zombot Dark Dragon summons zombies similar to how Gunpowder Devil and Blade-Wielding Hero summons zombies; the zombies simply rise out of the ground whenever it roars.
 * This and Zombot Sharktronic Sub are the only Zombots with a weakness. The boosted Magnet-shroom tugs on the Zombot's nose ring, stunning it briefly while Tangle Kelp entangles the turbine of Zombot Sharktronic Sub.
 * Its lobbed fireballs can kill zombies.
 * It is the second Zombot that is not fully visible. The first one was the original Zombot from Plants vs. Zombies, and the third one is the Zombot Sharktronic Sub.
 * In the Chinese Dark Ages map, it appears to have legs.
 * In the Chinese version, Dr. Zomboss does not wear his gladiator armor. Instead, he is wearing his lab gown.
 * It was inspired by a chinese dragon Zombot found in Plants vs. Zombies: Journey to the West.
