Known design projects

• No.17 Battle Convoy
  (with Shōji Kawamori)

• No.21 Corvette Stingray
• Powered Convoy

Micro Change

• MC-19 Binocular Robo Scope Man

Notes

• The two other inventors credited with working on Radi-Cassette Robo were responsible for creating the toy's internal electronics and AM-receiving microcassette tape (both of which were left out of the toy's release in Transformers as Blaster).
• Besides the above toys, none of the patents assigned to Obara appear to have gone into production, nor became the basis for other toys, meaning he never worked on Transformers per se.
• Obara also designed a robot that transformed from a wearable headset to a jet that was presumably intended for Micro Change. Whether it actually worked as a headset is hard to say.
• There is basically no other information about him on the internet. He came in, finalized Optimus Prime's design, and left...
