勇者王ガオガイガー
In the early 1990s, many of Okawara's designs made an unexpected turn back toward those of classic Super Robots with "Brave Exkaiser", the first show in Sunrise's Brave Series funded by Transformers manufacturer Takara. As the series of shows continued, Okawara would go on to design the principal robot for every entry in the Brave Series, culminating in his design of almost every robot seen in "The King of Braves GaoGaiGar"—the series' final televised entry—as well as the show's OVA sequel, "The King of Braves GaoGaiGar FINAL".
