Mega Man Battle Network 4: Red Sun

The fourth part of the Mega Man Battle Network series comes in two versions - Red Sun and Blue Moon - each with different enemies, battle chips, souls and characters. Once again you'll take on the role of Lan, who, together with his friend Mega Man.exe, must rid the Internet of viruses and other enemies from the cyber world. Unlike the previous games in the series, Mega Man Battle Network 4 focuses on a tournament system where players will encounter a variety of enemies to defeat. A new Soul Unison system lets Mega Man transform into his defeated enemies.
