Izzy Izumi

Koushiro "Izzy" Izumi is one of the main protagonist of Adventure, Adventure tri., and Last Evolution Kizuna and supporting in Adventure 02.

He is a member of the DigiDestined. He is partnered to Tentomon.

Physical Appearance
Izzy is a young man of Japanese descent with short reddish-brown hair, dark brown eyes, and a peach complexion. The third-shortest of the group when he was younger, Izzy eventually grew into an average height compared to his classmates and friends. Despite not being the athlete that Tai or Sora can be, Izzy is a rather healthy and lean young man.

Personality
Izzy can be described as introverted, analytical, and secretive. Due to his insecurities regarding his origins as an adopted child, he kept his personal life and feelings very close to the chest. This prevent him from allowing anyone to really get to know him beyond his immense intellect and skills with technology. This secretive nature faded away after having a hear-to-heart conversation with his adoptive parents about who he is and where he came from.

He often prefers to work with technology, having a tough time dealing with people, and often escaping into his laptop. Izzy is nothing if not creative, using his outrageous intellect to assess the world around him, and coming up with unorthodox solutions to daunting problems. This can be seen through his use of his laptop at the age of nine in the Digital World to outwit and outmaneuver the enemies of the Digidestined.

As Izzy grew up, his reliance on technology remained an ever-present and useful trait, inventing new technology and programs to assist him in his adventures throughout multiple universes.
