The "Mobile Suit Gundam" anime series first aired in Japan in 1979, and spin-offs featuring robots locked in intergalactic battles have won legions of enthusiastic fans in Asia, Europe and elsewhere.
In 2009, the 30th anniversary of the show saw an 18-metre-tall Gundam statue erected in a Tokyo park.
"When I created Gundam 35 years ago, I used my imagination freely because it wasn't real," Yoshiyuki Tomino told reporters in Tokyo today.
"That is what creativity is for -- when you dream of something. Four decades later, Gundam is growing into something new."
Plausible suggestions would be used in constructing the robot by 2019, the series' 40th anniversary and a year before Tokyo hosts the Olympic Games.
