Bibbo Bibbowski, Supermans noble friend from Suicide Slum, is a Catholic.
From: "Bibbo Bibbowski" page on Wikipedia.org website (http://en.wikipedia.org/wiki/Bibbo_Bibbowski; viewed 24 May 2007):
"Bibbo" Bibbowski is a supporting character in Superman comics. He first appeared in Adventures of Superman #428, by Marv Wolfman and Jerry Ordway, when Superman was looking for information in a Suicide Slum bar called the Ace O' Clubs. Bibbo, thinking this was "some clown in a Superman suit" punched Superman, and damaged his hand. He gained respect for the Man of Steel because "yer tough". He would later refer to Superman as his "fav'rit".
Later stories established Bibbo as a longshoreman and former boxer, however he remained largely a comic relief character, portrayed as vaguely well-meaning but not too bright. His admiration for Superman seemingly remained based on physical strength, as his admiration was briefly transferred to Lobo when the Czarnian appeared tougher.
He became a more significant part of the comic when he found a winning lottery ticket and used the money to buy the Ace O' Clubs bar and help those living in the Slum. By the time of the Death of Superman storyline, he had come to represent the idea of ordinary people living up to Superman's example.
Bibbo briefly took care of a small white dog named Krypto, not to be confused with the current Kryptonian dog of the same name. The original Krypto's name arose when the engraver Bibbo hired made a mistake. It was supposed to be Krypton.
Bibbo would briefly create an alternative identity for himself after Superman's death. He temporarily named himself Superdood in hopes of helping fight crime while Superman was away.
In The Power of Shazam!, Ordway introduced Professor Bibbowski, Bibbo's pacifistic scientist brother.
Bibbo played an important part in the alternate universe story 'Superman The Dark Side'. He watched out for Jimmy Olsen, kept an eye on Lois Lane and fought back as much as he was able against invading alien forces.

Ok, so in recent films it's been apparent that Daredevil and Nightcrawler are Catholic...
So, who else out there could be fielded in a "Catholic" Heroclix team?
Oh yea, Bibbo Bibbowski, one of Superman's friends, is Catholic. During the 'Death of Superman' saga he prayed the 'Our Father', made the sign of the cross asking God to give the world strength during Superman's death.
Oddest. Topic. Ever.
But not a bad one. I just never expected to see it. I wouldn't use the "Our Father" as a sign of being Catholic. Many denominations use this. The same is true with the ideas of confession and alter boys. Eastern Orthodoxy has both...
And also don't look at funerals too hard. I've been to Lutheran funeral that look a lot like Catholic, as do Orthodox.
