"(These designs) embody tradition, the future, cuteness and sophistication, and I believe that they represent today's Japan perfectly", said Yoshiko Ikoma, deputy head of the Tokyo 2020 Olympics mascot selection panel.
They can teleport, move objects with their mind and talk to stones and the wind - they're the official mascots of the Tokyo 2020 Olympic and Paralympic Games.
"I thought that something combining futuristic and traditional elements would perfectly fit the image of Japan and Tokyo", he said.
"It has strong sense of justice, and is very athletic", an organiser said.
Earlier, 2042 individuals had submitted their designs and the experts shortlisted three of those for public voting.
A total of 6.5 million Japanese children - from schools in the country and overseas - cast their vote between December 11 and February 22 and then the unveiling happened.
The designer of the winning mascots is Ryo Taniguchi, who graduated as an art major from Cabrillo College in California, and is now active as a character designer/illustrator.
With nearly 110,000 votes, "Mascots A" were selected.
He added that he was thinking about becoming an athlete and possibly trying to take part in the Olympics as a ping-pong player.
One of the students at Hoyonomori Gakuen School where the selection was announced, Miu Kawa, 12, said she was very excited the "futuristic" designs won. Meanwhile, the Paralympic mascot wears a pink and white chequered pattern, "has a dignified inner strength and a kind heart that loves nature". The event has not given names to the mascots.
Taniguchi will be awarded ¥1 million and a ticket to the opening ceremonies of both the 2020 Olympics and Paralympics.
The Tokyo 2020 mascot will hope to replicate the success of Soohorang, the cuddly stuffed tiger from the Winter Olympics in Pyeongchang handed out to athletes on the podium.
The Rugby World Cup, which takes place in Japan next year, has already unveiled a pair of pot-bellied lions as its mascots.
