Red Dragon

The Red Dragon is a new mob that is planned to be included sometime in the future, post the Minecraft 1.0 release at Minecon.

History
Originally Dragons were a possible planned mob hinted at by Notch during the Spider Jockey update. He also mentioned that dragon lairs may be an addition. They remained a potential work-in-progress until the Enderdragon was announced.

Notch has in the past stated that if Dragons are added, they will not be able to be mounted because it would put pressure on servers in SMP.

In September of 2011 Notch stated that "dragons will be added eventually".

On October 7th 2011 Notch revealed the existence of the Ender Dragon.

On October 12th 2011 Notch announced Red Dragons "After release, I will totally work on slightly less dangerous dragons that don't destroy terrain and can land and whatnot. They will be red."

On October 12th 2011, in a Reddit post Notch also said. "They will be different dragons. The Enderdragon will probably become larger, and the ones in the main world will be this size, won't go through terrain, and will be red because dragons are red."

On October 12th 2011, in a twitter post Notch also said: "Dragons have 6 limbs" Which would consist of 2 wings, 2 legs and 2 arms.
