Atsu and Ty

Atsu (アツホ) and Ty (タイチ) are Shuko Kido's young twin brothers. Shuko pays for their tuition in a school. In MegaMan Battle Network 4, they go to the stadium to watch Shuko's NetBattle, and they say they got money to buy a new washing machine for her. AquaMan misunderstood their conversation and thought Shuko was going to replace him for a new NetNavi, which makes him sad and flood the Net with his crying. Atsu asks Lan Hikari to help them find AquaMan and MegaMan explains the misunderstanding, returning the Net to normal.

Atsu and Ty also appear in the anime MegaMan NT Warrior.

Trivia

 * Atsu and Ty, as revealed in Mega Man Battle Network Official Complete Works were originally named Appo and Dah. Appo and Dah from Mega Man Legends 2 were Shu's younger brothers. Their names were scrapped for unknown reasons, possibly because they were odd sounding names in the Battle Network universe.
