The War Within

It happened spontaneously, but I love AU. So… Avatar Hiccup. Hiccup considered himself an ordinary person before meeting Toothless. (Dragons can be equated to spirits, i mean relationships between people and them). Then he discovered his talent as an airbender and Toothless became his teacher. Later, other talents were discovered, which made it clear that Hiccup was an avatar.

Astrid became his waterbender teacher. Snotlout was an adept of firebender, but he sincerely did not understand how to teach, because he himself used magic on a subconscious level. Fishlegs is an earthbender, but he did not go beyond the amateur level and could not become a teacher. The twins are always on their own wave. Ruffnut is a master in airbending and can perform techniques with clouds of gas, while Tuffnut is not a master, but is ready to set fire to the gas with his sparks at any moment. The twins always come in a set.

Brothers Grimborn! Lord of Fire Viggo. The aesthetics of blue flame and lightning were created for him. So I couldn't resist. The hottest flame and deadly techniques of lightningbending made him the most terrible opponent for the young avatar, but in the future, he will become the teacher of fire magic for Hiccup. I endowed Riker with explosion magic, as for me, it suits him perfectly. An explosive mixture of rage and bloodlust.
