You cannot tame an Enderman in Minecraft. If you don't look at them, they will not attack you though. If you wear a Pumpkin on your head, they will not attack you, regardless if you look at them. But be warned, if you hit them, they will attack you.
Unless you are using mods, you can't tame birds because there are none.
There are no such things as nightmares without mods
You can't, unless your using mods. You can tame ocelots and wolves though.
Not in vanilla Skyrim. With the mod "Mofomojos Horse Whisperer" by MofoMojo, you can get a spell to "tame" stolen horses. You can find this mod at Nexus Mods.
The fanmade enderman is a version of the enderman MOB in Minecraft 1.8. The fanmade version of the enderman was popular because it was released before Minecraft 1.8 came out. Since the release of Minecraft 1.8, the fanmade enderman is obsolete.
No. a Enderman is based on a slenderman. Notch wanted to make the Enderman look a bit more frightening than a mutated Steve
No, they are no enderman in Pocket Edition of Minecraft 0.8.1
Currently the ability to tame the Ender Dragon in Vanilla Minecraft is impossible, and will most likely not be implemented. Although this can be achieved with the use of mods and thankfully there are some out there that allow the ability to do so.
Zombies are hard-coded to always be hostile toward the player, so without using cheats or mods, there is no way you can tame a zombie, as such. However, you could consider trapping a zombie instead.
Enderman is modeled after Slenderman; Notch wanted a creepy looking fellow.
There isn't one. Wolves are already in Minecraft. There are other tools and mods that can help you find and tame one though.
