Toothless is playful and intelligent with a puppy-like energy. When flying through the dark, he shoots purple flames called plasma blasts in all directions, which bounce off nearby surfaces to give him an accurate reading of his surroundings Toothless, although he cannot speak, shows a lot of emotions through his facial expressions and body language. Toothless has even been shown to make a laughing sort of noise and often gives a few critical looks if he doesn't like the looks of something.
