Leon's hairstyle is as well, and Daley is less, well, " flaming". Priss still sings, only the sound is more modern. Much of what was discarded is what many hold to be defining features of the OAV, namely the 80s rock theme, Leon's hairstyle (and Daley's clothes). Also, (B/V)oomer designs were more varied, shown as robots in service around the city randomly going mad. Some characters were added, none were subtracted, and their introductions and back history were changed. While all of the original characters and suit designs were kept (and changed later in the show), they all underwent significant updating.
While the sci-fi aspect of Bubblegum Crisis could be continued, many parts of the OAV series had to be left behind. The story still revolves around the fight of the Knight Sabers against the Boomers/ Voomers, and the superpowerful corporation Genom, and their interactions with the AD Police and their agents. In 1998, AD Vision provided funding to AIC for the creation of the Bubblegum Crisis TV series, "Bubblegum Crisis: Tokyo 2040" in exchange for exclusive DVD distribution rights in both the US and Japan (BGC2040 LDs were released in Japan), and extensive merchandising and character licensing rights. The 3 remaining episodes, later known as Bubblegum Crash, were finished and released by AIC. After a short 8 episode OAV series, AIC and Youmex, the producers of the first Bubblegum Crisis, split and the show was never finished.
