Adamant Blaze is an earth pony with aspergers, and has a lot of trouble socializing with other ponies. In a lot of social circles he is unaccepted, and is bullied, picked on, and treated horribly. He came to Ponyville around the time of season 2. The only one he truly considers as a friend is Pinkie Pie. Pinkie is friends with everyone in Ponyville, but she especially likes Adamant Blaze.
Blaze also has a crush on Pinkie, but is not brave enough to tell her.
