TheHandlessDemon

Originally, Kalin started as a cheerful and good person, looking out for his teammates and giving hope to them. But after his team conquered the entire city of Satellite, Kalin became obsessed with protecting what they worked so hard to obtain, growing paranoid into believing that any duel gangs not under his control were a threat to the order they brought. This caused him to begin dueling people recklessly including kids, harming them in the process, which eventually lead him to challenge the city's security, causing his downfall, being captured by them and sent to prison to die blaming Yusei for his capture.
As a Dark Signer his personality has become more crazed, bursting out in insane laughter at his opponents and enemies' pain and misery. He also showed great hatred towards his former teammates, Jack Atlas, Crow Hogan, and especially Yusei Fudo, to whom he would often call a traitor and exclaim "You betrayed me!"
After his death and revival he came to realize that all his pain came from his own mistakes, regretting what he has done in the past. Depressed and guilty he ventured to Crash Town looking for a place to die, uncaring of what befalls him. His method of dueling shows that as his monster's effects act like Russian Roulette. But after seeing Yusei and the kids, West and Nico attempting to save him, Kalin regained his self-worth and kindness as he vowed to protect them and all the citizens of Crash Town.
