Character from the anime series Digimon. Izzy is the computer geek of the group and carries a pineapple laptop with him everywhere. Discovered that information is a living, tangible substance in the digital world, and applied this theory by emailing the group across the continent, but never repeated the trick. Seems to have a special connection with Gennai. He uses the crest of knowledge to help Tentomon, a large, red, cybernetic beetle, digivolve.

His full name is Koushirou Izumi, not Koushiro Izumi. The "u" was inexplicably chopped off by the dubbers in the first episode's character introductions.
