Tadashi Hikari (光正 Hikari Tadashi) was the father of Yuichiro Hikari and grandfather of Lan Hikari and Hub Hikari. Tadashi is Dr. Light's counterpart in the Mega Man Battle Network universe.
Personality
Tadashi was an elderly man who was truly kind and a brilliant scientist. Although he sadly never got to live long enough to see the birth of his grandsons, he would have been very proud of them. Lan still loves his grandfather and wished that he would have just lived a bit little longer to be with him.
