Kowalski is the brains of the team; their group strategist and inventor. He's loyal, even if he's not always completely honest about his inventions. He's also highly narcissistic - both confident and boastful about his brains and his looks - so much so that Kowalski will regularly try out his completely untested inventions on himself. Sometimes it ends well. And sometimes... it doesn't. He loves to demonstrate his encyclopedic knowledge of anything and everything and can be such a show-off that Skipper has created the 'Show-Off Jar', which Kowalski must put a quarter into every time he shows off his intellect unnecessarily.

Here is a reference video of what Kowalski sounds like https://youtu.be/BGf7dhRffbQ https://youtu.be/BGf7dhRffbQ
