Kwazii is a daredevil cat with a mysterious pirate past. He loves storms, exploring, general excitement and swashbuckling.

As befitting a pirate and an old-fashioned sailor, Kwazii believes in many different kinds of sea monsters and legendary beasts. Oftentimes he seems to try and scare his crewmates with his spooky stories. He is hot-blooded and is considered to be one of the bravest of the Octonauts, but does have arachnophobia and has a soft heart for cute small animals, especially the babies. Kwazii isn’t very patient and doesn’t like chores that he seems boring like cleaning or science, and is always up for a little excitement.

He speaks with a Cockney accent and a typical sea ferrying dialect.
