Sigma and Piemon
He is the first to go out and battle for Neo against Zero. He talks via his computer in the battle and only talks normally later on. His feelings are connected with Piemon. When Zero is fighting Piemon, some of Piemon's mask breaks at the sametime some of Sigma's does. Taichi gives him the chance to quit and let Piemon be spared.
Sigma is partially greatful and he and Piemon leave. Neo however is toally annoyed and orders Arkadimon baby to fight Piedmon. Sigma is behind a Glass window with Neo unable to do anything. At the point of Piemon's death Sigma screams out as does Piemon. His data is then absorbed by Arka who digivolves to Child. Sigma eventually joins forces with Taichi and starts to sabatage Arka's Data but fails.
As a young boy he doesn't seem to have anyfriends *and he looks a lot like Kenny from Beyblade but without the glasses (before the mail starts you KNOW Digimon came before BB)* He also keeps friends with the others on his return to the real world.
