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.
