When I was coming up with a new post for a heroic I looked at all the heroics in the Dragon Book and realized that there needs to be more heroics related to space. The only heroic related to space would be the High Comet Dragon. (Might have missed some.) It would make sense to be in the game. It would also probably be one of my favourite heroics.
These are some of my ideas.
Possible Elements: Primal, Earth, Water and Nature.
Trained Moves: (Primal) Archaic Roar, (Earth) Asteroid+, (Water) Whirlpool+ and (Nature) Beehive.
Moves: (This is something new, but you are still allowed to suggest beginning moves) Primal: Slash of Ages, Earth: Meteor Shower, Water: Typhoon, and finally! Nature: Leaf Blast.
Source: Limited Time.
Description: Friends with the High Comet and the Origin Dragon, creating new planets and galaxies for dragons to live on. He loved creating Planets so much that he decided that he would start something, The Big Bang! After that, He could finally relax.
Rarity: Heroic (This is new as well) But I will probably not use it very often. Thinking about it, I will rarely use this in new heroic ideas. People usually have enough common sense to figure out what rarity the dragon is.
