The Vision is a synthezoid and a long-time member of the Avengers. The Vision was apparently destroyed by his ex-wife, the Scarlet Witch, during the "Avengers Dissassembled" storyline. But a rebuilt incarnation of the Vision currently leads the Young Avengers.

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?

Hawkeye is Catholic. Remembering his mini-series, when he was pretending to be dead his had a Catholic funeral (if memory serves me right). Kingpin was portrayed as Catholic (link to the whole mafia thing) in early DD. Vision also played with the whole religious-Catholic thing at one point.
[The following are Catholic characters:]
Great characters and although the press has been bad lately - Great Religion.

...Probably the best comic you could find to figure out who believes in a god or a god, or have deep faith in God or a god would be:
The Goddess uses the heroes' faith and belief in gods and such to recruit heroes.
Here are a list of Avengers who are "believers" so are recruited by the Goddess:
The so-called "non-believers" that the Goddess didn't choose:
Beast (although Beast claims to believe in a god, but Vision counters with "Obviously because your belief in a supreme being is not as deeply felt nor well known as the others.")
Quasar (which was stated in his own book)
