>>50868003He had more of a presence beyond the TCG in Japan. As part of the band Suzukisan, he performed a lot of Pokemon-related music in the early days, including both the original and the gen 2 Japanese equivalents of the pokerap.
I don't think Imakuni? will show up in any modern pokemon products though. Even if there are probably a lot of Japanese players who remember him fondly, he's a little too weird for modern Pokemon and doesn't fit with the franchise's image anymore. It's a shame ;_;
