Seventeen's Dino Blood Iron, who looks like a real character rather than an alter ego

Seventeen's Dino's alter ego, Picheolin, who announced his official debut.

Dino uploaded photos taken after transforming into a Blood Iron Man!

Dino, who seems like he isn't just an alter ego, but simply Blood Iron Man himself.

I have no idea what song they will debut with, so I'm looking forward to it.
