It is in Mexico. On the map in the top right of Mexico there are 3 galloping horses. The unicorn is in the field next to the canyon.
BUT, you have to have found and broken the 3 horses of the apocalypse and killed the chupacabra before the unicron spawns.
Good luck :)
To get the unicorn you have to get to mexico first but do your challenges and you have to be rank 5 to get the unicorn you don't have to be rank 5 in sharpshooter or the tomahawk thing just the one when you have to kill 2 bears, 5 wolfs, and 3 cougars with your torch but anyway when you get to rank 5 in undead slayer or something you have to kill the chupacabra and thats going to be west of Torquemada in the field like go to your map and zoom all the way out then you should see 3 horses and its going to be in that field and thats where the unicorn will be also so good luck finding it and it won't say nothing like "there is a mythical creature in the area" you just have to find it but it should be easy cause rainbow comes out from the back of it when it is running. If you could not find it and you have a ps3 add beastyman31 and he will tell you where its at
You have to do a certain challenge
its something like killing certain animals then you have to find the chupacabra kill it then look for the unicorn somewhere to the north of mexico?
