Full Name: Yai Ayanokoji Age: 8 Yai has a NetNavi just like her friends and his name is Glide yet he's more of a butler than a fighter. Yai has a very high IQ which managed to get her skipped to 5th grade. Yai doesn't even bother with NetBattling, but she's also rich and her family lives in a mansion.

Full Name: Dex Oyama Age: 11 Dex is Lan's rival sometimes and GutsMan's Operator. He has a little brother named Chisao, that believes Dex is the best Operator on the world; and Dex tries desperately to maintain his respect.

MegaMan is Lan's NetNavi and together they make a great team. MegaMan is sometimes referred to just as Mega or Rock. MegaMan was originally Lan's twin brother Hub Hikari who died of a heart disease but his father revived him as a NetNavi from his data. As an opposite of Lan he is polite and well behaved.

Mayl's NetNavi. While known as a Healer Navi more than a NetBattling Navi, she has shown capable of holding her own fights when needed. She is kind hearted. She is hip and cool, with the heart of a champion NetBattler.

Glide is the NetNavi of Yai. He's not great for fighting so thus he relies on Yai using rare Battle Chips that she provides him with to do devastating attacks. He is very calm and... Butler-like.

GutsMan's Operator is Dex. While not very bright, he is a super strong Navi that relies on brute force. GutsMan is a loyal friend and fights beside his allies. He acts just like Dex sometimes...
