No, it is just a stylized dragon with transparent background I found on a random site a long ago. I'm using it in MechWarrior 4 when I play. Yes, I'm into older games. XD
If I may have a question, how can I disable the boss cam? I want to stay in simple behind view during the battle but most mods don't support this. In CM it is disabled and I hope it is just a simple edit somewhere in the scripts too.
