Susie

Unlike the other members of The Fun Gang, Susie is quicker to violence and attacks using her axe, though she doesn't truly wish to kill anyone. Brutal and unforgiving in combat as well as being naturally strong, Susie is a force to be reckoned with and makes that clear by looks alone. It really isn't a good idea to get on her bad side. Susie is a little more merciful than she used to be, but a fight is still not recommended. She isn't that fond of many other dragons beyond The Fun Gang, but her best friend is Lancer. Seriously, don't mess with him. That would be getting on her worst side.
Susie is less mean than she was before joining The Fun Gang. She was prone to bullying other dragons and used to make fun of Ralsei for various things before they were on better terms with one another. She's trying to be friendlier since a series of events changed her perspective.
Upon initial arrival to the Tribe of Roaring Thunder, Susie jeered at the idea of being trapped. Her friends urged her to stay, even just for a couple days before she tried to leave. It was around this time another dragon arrived, a ridgeback named Gerathon, who's first idea was to jostle his way past the many dragons of the tunnels and back out into the territory, snarling that he refused to be kept by superstitious hatchling's tales.
Susie latched on to this idea, and a day later early in the morning set off herself, believing nothing would really happen if she crossed again and deciding to prove it before coming back and telling her friends she was still alive and that there was no need to believe these dragons.
Of course, plans like that aren't usually followed through with when you find the body of a certain ridgeback limp at the bottom of a ditch.
