Aviva Corcovado (voiced by Athena Karkanis) -- Aviva is the leader of the Tortuga gang, second in command to Chris and Martin. She designs all of the inventions the Kratts use, usually inspired by nature. She is an engineer and inventor. Once she has made up her mind, it takes appealing to her emotions and overwhelming evidence to change it. She is also competitive, rivaling Zach in invention contests, the Kratts, and even nature itself, most notably in "Cheetah Racer '', where she bet that she could invent a land vehicle that was faster than a cheetah, although she was proved wrong. Her Creature Power Suit color is purple. For instance, she used this to become a Lawes 's parotia in "Birds of a Feather '', a groundhog girl in "Groundhog Wake Up Call '', a Thompson 's gazelle in "The Amazing Creature Race '', and a giant female praying mantis to humiliate Zach in "Praying Mantis.
