Weirdly, neither 'jesus' nor 'christ' appears in this list. While reddit's obviously hugely popular internationally, I'm assuming there's some North-American cultural impositions, de facto or de jure, in play. In my small circle there's a lot of compound expletives that include one or the other.
We can trace back some common expressions of surprise or frustration to this character's name / title - crikey, jeepers, gee, I'm sure there's more - but I suppose those are both sufficiently linguistically distanced to be safe, and in the context of TFA somewhat anachronistic.
On reflection nothing as sophisticated or delicious as two of my favourites -- twatwaffle or cockwomble (only the former got a mention in TFA). Typically it'd be Jesus followed by one of the stronger profanities - especially that one that Americans seem to be surprisingly sensitive about, but which Australians will exuberantly drop on a whim.
To wit - while the f-word appears ~ 14 times in the article, the c-word is notably absent. (EDIT: actually it's there, once, in a PNG, which is why it didn't come up on page-search.)
Referring to TFA's matrix, it looks like only a handful of potentially comfortable combinations that could use this fictional character's name against the suffixes and prefixes they've identified -- but they would feel a bit contrived.
