Hiroshi Kotetsu

Hiroshi Kotetsu is an archaeologist and the father of Shiko Kotetsu as well as the creator of Shin Kotetsu. While he is never seen in person, he is named after and based on Hiroshi Shiba, the main protagonist of Steel Jeeg.

Appearance
Hiroshi resembles his namesake with semi-spiked brown hair, brown eyes, and the same figure, ironically appearing to be much younger than his actual middle age.

Personality
While Hiroshi loves his daughter Shiko, they do not communicate much partly due to Hiroshi always being away on his expeditions and Shiko resenting him for making her into a cyborg. This implies that Hiroshi is a fan of Steel Jeeg and wanted to make Shiko in her image, albeit without her consent. Since Shiko never wrote back and that Hiroshi wanted his daughter to have some company, he created Shin based on the new Jeeg robot who he treats like a daughter and wants them to get along. Hiroshi seemed happy that Shiko made friends.

History
While Hiroshi never appears in person as he is always away on some far off place for his expeditions, he talks with Shiko over postcards that she always rips up out of spite. However, he seemed happy that Shiko made friends. At some unknown time he created Shin who he sent back to Fujino Suzuno for them to meet which erupted in a big fight.
