Lan

Lan Hikari (Netto in Japan) has a NetNavi who is named MegaMan.EXE in which he is the star. Almost. Lan is, of course, the son of Dr. Hikari. He is always hungry and he wants to become the greatest NetBattler ever. But he is beaten by Chaud quite a bit.

Trivia

 * Hikari in Japanese means "light", which means that his Gramps' official title (from MegaMan Battle Network 3), in English, is Dr. Light (quite fitting, since they look almost identical). His first name (Tadashi) means Right, a pun on the naming confusion in America.
