In case you are interested, King Arthur is the runner up for most badass Catholic doodle (King Arthur would have been Catholic if he ever existed).
And in third place, is my quasi-Catholic work is this triptych depicting Beren and Luthien. My defense for adding this work to the list? Well, Tolkien was Catholic and Beren was badass. That's close enough for me to add Silmarillion-based art to this list.
