>>23340933From what I'm aware he's:
Performed surgery on Shouma when he was young to augment his potential with the Red Gavv, but nothing came of it... yet
Operated on Hanto after he used Dark Choco to relieve his symptoms
Duplicated the VRAM system for Hanto to use
Created the Gochipod using his own teeth
Created an antidote for Lakia's venom
But hasn't created a Gochizou. Shouma created almost all Gochizous in the series. Any other Gochizous that were used by any Bitter Gavv users were either created by Shouma clones, or through an unknown method by Nyelv (Including the two original Vram puddings) that will probably be revealed next episode.
