Biography
Eager to win a trip to Australia in an upcoming tournament, Jonouchi trained Joe hard. He continued to train him during school hours, rather than turn the Digital Pet off.

Jonouchi connected Joe with Yugi's pet U2 for a data exchange. As Digital pets commonly take after their owner, Joe began to bully U2, like how Jonouchi used to bully Yugi. The 2 pets became friends afterwards.

After Kujirada used got his pet, Devil Master, to eat Anzu's pet Peachy, Jonouchi connected Joe to Devil Master to battle. Joe initially caught Devil Master with a sneak attack, but was ultimitely eaten too.

In the manga, using data it incorporated from its data exchange with Joe, U2 became more powerful and was able to defeat Devil Master.

In the anime Devil Master was instead beaten by Honda's Super Strawberry and U2 beat Haiyama's pet, after powering-up due to its data exchange with Joe.
