Strike.

The most well known aspect of Stike class dragons is that they have incredible speed. Even if a dragon meets all other criteria to fit into the Strike class, if they are slow other dragon experts will look at you odly for wanting too add that dragon too the class.

Strike class dragons tend too breath other forms of plasma then fire. For example the Night Fury's plasma balls or the Skrill's lighting.

Dragons in this class tend to have good eyesight and aim.

These dragons tend to have powerful striking power.

They may also have abilities that allow them too navigate there surroundings while they travel at fast speeds.

If you don't know how to seduce a specific Stike class dragon, a good bet is too show them how fit you are. Trying to show off how fast you can run is pointless as even the fastest runner in the world will appear pathetically slow to a Strike class. Instead, show them how long you can train for. This will more then likely arouse them.

(In the canon Strike class dragons are known for there jaw streangth and intelligence. All dragons in this universe are as smart as humans, so thats a none factor. The jaw streangth thing makes no sense to me since there are no Strike class dragons that are shown to have particularly strong bites. Thats why I removed that aspect from the list.)
