Great Mazinger
Boss was a main protagonist in both Mazinger Z and Great Mazinger starting in episode 3 of the original series. Boss and his gang, Nuke and Mucha, were the comic relief characters. Boss began as a bully and Kabuto Koji's rival at school, but quickly became an ally, often scouting for Mazinger Z on his motorcycle, or getting into some sort of slapstick mischief. In Great Mazinger, Kabuto Shiro and Bakarasu also join the gang with the latter always annoying Boss. He is also Sayaka Yumi's long-time school friend and has a huge crush on her. In the Great Mazinger, since the firsts episodes, he fall in loves with Jun Hono as well, stricken by her beauty; but she doesn't feel the same for him, and worse, Tetsuya, while not officially her boyfriend, doesn't like Boss's attempts and often fights with Boss.
