Taking place from 6-9 August the 37th annual event will take place at Ashton Court Estate, and will feature more than 100 hot air balloons.
The Power Rangers balloons will form part of the fiesta for the first time, and will be launched at the Night Glow event on Thursday evening (6 August) at 9.15pm.
It will be the only brand at the event with two balloons participating, and visitors will be able to watch the team prep, inflate, launch and land the creations, which have been designed to look like the red and pink Mighty Morphin Power Ranger helmets.
VIP guests will also be invited to attend a special Power Rangers picnic on the Friday afternoon, which will feature Power Rangers Dino Charge meet and greets and themed giveaways.
Agency Miss Jones & Co is working with Saban on the activation.
Gustavo Antonioni, managing director, consumer products EMEA at Saban Brands, said: "The Bristol International Balloon Fiesta is a weekend of non-stop family fun, which is a perfect fit for Saban’s Power Rangers brand."
