I've just remembered something. When I was at sixth form, a classmate shared my fondness of the old 12ep OVA*, and Pokémon arrived in the West. I'm sure I've got a Pikachu Guyver drawing from back then, somewhere in my old art portfolios...
*I once screamed "GUYVAAAAAAARRRR" on my turn in a game of 'guess the line' in the college workshop. He figured out what I was referring to, and I got a written warning for inappropriate behaviour.
