Spike

Appearance
Spike is a cute baby dragon. He was hatched by Twilight when she was a filly and now he helps Twilight in her studies, making, sending letters by blowing it and receiving letters too by burping them. Spike has also a huge crush on Rarity since they met and he has been giving diamonds to her lately but sometimes he eats them cause he eats diamonds and crystals and Rarity often call him "Spikey wikey" because one of the episodes, Rarity told to Twilight that spike is the cutest thing in Equestria. Spike has green eyes, violet scales but on his tummy is yellowgreen, green spikes on hi back and has a pointy arrow on the tip of his tail. Spike's greatest fear is Twilight tells to him that she doesn't need him anymore and wants him to go away to another pony who would make him an assistant.

Skills
This cute baby dragon is skilled to help Twilight in her studies and sending letters to anypony by blowing on it and receiving letters from anypony by burping them. He is always generous except that episode when it was Spike's birthday and become a selfish ginormous dragon and he was saved my Rarity's memories by telling her the gem was given to her from Spikey wikey the "most generous dragon" in Equestria.
