LunaWisp was my Peacebringer on a superhero game called City of Heroes. CoH was created by Cryptic Studios and published by NCSoft. Sadly, it was killed off when the company decided to concentrate on more modern games.
The Peacebringer, a being of light, was formed from the fusion of an alien energy being called a Kheldian and a willing host. At higher levels it gained the ability to shapeshift into what was basically a flying turret (Bright Nova) or a tank (White Dwarf).
The 'flying turret' or Bright Nova form. Basically a hard hitting
ranged DPS character. Annoyed the heck out of non Kheldians in the team
because of the whooshing and shooting noises the developers decided to
give the Kheldian's attacks.
They were still generally welcome in
teams though, they brought a lot of additional firepower and gained
themselves from being teamed with non Kheldians.
