29 Trickster Dragon in DxD

So, this one needs a bit of backstory, which I'll be providing. Back when I first watched Highschool DxD, I used to read the Monster Manual for DnD, so at the time I liked that the Copper Dragons had a sense of humor. I wrote an original character with an original Sacred Gear, but I never did anything with him. So, I'm using his Gear's ability as the power for a new Dragon, one who can rival even the Heavenly Dragons. So, the Gear's ability was "Imperfect Mimicry", which would allow it to copy other Gears' powers, albeit at a fraction of their full prowess. I'm upgrading that into "Perfect Mimicry" for this Dragon, which allows him to mimic absolutely anything.

Known as a Trickster to all, he uses his powers to cause mischief amongst the various Realms. In his Dragon form, he's a Western-style dragon, with beautiful copper scales that glitter in the sunlight. In his Humanoid form,(That means Human, Devil, Angel, or Fallen Angel), he is a tall and extremely good-looking man with a jovial smile usually plastered on his face. His mischief isn't malevolent, it's normally all in good fun, but when angered his jokes turn into threats.

He gets along well with just about anybody, but people who can appreciate his pranks are his favorite kind. Those who are his friends aren't completely safe from his antics, but they generally aren't his main targets. He also enjoys the various media that Humans have created, including anime and manga, though his favorite things are movies. His friends also enjoy a great deal of protection, which he grants generously. I haven't really gotten an exact name down, but here's a possible suggestion; Kaldrad. Of course, I could always use a name from mythology, but I don't want to take the easy way.

Obviously, I shouldn't really need to write a possible plot, since it's literally just the normal plot with the addition of the Trickster Dragon. I mean, there definitely will be a change in the main plot, just the beginning would be mostly the same.
