[@Zardoric] That's.......a nighfury...?

Ok....first, power is too OP. You can get them to do anything, for example, have a dragon run away in a curtain direction, knowing there is danger towards that way. 

I would like you to change the power please.

The type of dragon is 'Plasma' (If you want to make it a nightfury.)

Either way, just name some of the effects your breath can do if you choose not to go the HTTYD Route.

The bio isn't needed too much, just note down how he felt while he was waiting to hatch, where he was and how close he was towards the other eggs, etc.
