Asobin's last appearance giving advice was in the manual for Makai Retsuden (Kung Fu Kid) released on 17th May 1987. He continued to appear in manuals on the page describing the correct care and maintenance of cartridges and cards during the rest of the Mark III releases, although no longer provided his customary gameplay advice. Professor Asobin was succeeded by Opa-Opa from the Fantasy Zone series of games as the next iconic mascot of Sega.
