Did Katsura Masakazu help design Cell?

[Zebra]

I read on this Spanish fansite: https://k2r.es/news/1451/katsura-y-tori ... a-amistad/

También es sabido que el diseño original de Cell, es propio de Katsura, y que pasado un tiempo Toriyama recuerda como una tortura tener que dibujar todas las manchas sobre la piel de este personaje. Por otro lado se comenta que Trunks, o al menos su vestuario podrían ser una idea de Katsura. También resuenan que A17 y A18 fueran idea de Katsura.

It's also known that Cell's original design was Katsura's own, and that after a while, Toriyama recalls how it was a torture to draw all the marks on this character's skin. It's also rumored that Trunks, or at least his costume, could have been Katsura's idea. It's also rumored that A17 and A18 were Katsura's own ideas.
