I can imagine Blood baron as a Deathscythe based Gunpla. And it's ability isn't a far stretch since the star build gundam can do something similar. Honestly I'd REALLY like to see Echo Barbatos against this guy. Since Barbatos Lupus Rex is very werewolf like. Vampire vs Werewolf except with robots. 

Divine Shogun definitely sounds like the Gunpla of an eccentric guy who likes to flash their culture. Definitely someone who'd end up as a rival or enemy.  

And the Phantom Rogue Definitely sounds like a rival. If this was an anime then the Intro definitely has the Joker and Phantom battling each other.
