Digimon Adventure
Izzy was the brains of the group many times he helped the group out of difficult situations. He is the owner of the Crest of Knowledge, mostly because the fact he is not only extremely smart but also has a hunger for the truth.

Digimon 02


Although he grew, he is still short compared to the other DigiDestined - he is only as tall as the new soccer team. Izzy seems to have a lot of free time and often stops by the computer club at the elementary school to help the new DigiDestined in almost every episode. He is still into computers and is curious about the D-3s and other items the new DigiDestined have access to.

Digimon 02: Diaboromon Strikes Back
Like in 'Bokura no Wargame!' Koushiro still was responsible for the techie stuff. He was the one who gathered all the Chosen Children (including Tachikawa Mimi who's in America) to help defeat Diaboromon causing havoc on the net and the real world.

Digimon 02: Series Finale Epilogue
