"Pen is a somewhat cocky and loud person, originally obsessed with having control over his own life, he learned to go with the flow and live life to the fullest. He's often willing to poke sarcastic fun at others, especially his opponents. He's very energetic, and although he's not always the best at understanding his emotions or others, he uses his gut instincts to try and figure things out."

Excited, energetic, flashy, cocky, sometimes sarcastic. He tries to keep a grin on his face, capable of exploding with energy at practically any moment. His sarcasm and cockiness often sounds casual rather than snide jabs.
