"The Stainless Steel Rat" is the GOAT nickname for a fictional hero.
He was the hero of the Stainless Steel Rat books by Harry Harrison. His full name is James Bolivar diGriz, aka "Slippery Jim diGriz." Also good names. Harrison had a good ear for how names sound.
I loved those novels when I was a kid.

I also loved Harrison's "Deathworld" novel series, whose hero also had a pretty good name — Jason dinAlt.

On the other hand, "Jake Cardigan" is a ridiculous name. He was the hero of the Tekwar novels and TV series, created by William Shatner. Ron Goulart ghostwrote the books.
@francis Afraid I missed that one.
