If, on the other hand, we'd been (for example) shown the files covering Flex's parentage and under father there was visible "Wolv..." (with the rest cut off by the page), we'd likely have gone with "Wolverine (possible father)" or words to that effect. We'll bridge a gap, where something was shown but not explicitly spelled out, but we limit the level of outright new info and anything that is added is closely scrutinised.
Where creators are contactable, we try to always go to them to see if they'd like to fill in any missing details, or if they are okay with us doing so, or if they'd prefer to leave the details unrevealed for now. When that's not an option, then the decision whether to provide names gets influenced by various factors, one of the biggest being whether there's anyone else using the same codename - when two or more share a codename, having a real name for clarification purposes is helpful. There's at least two other Breakdowns, and no less than five other Januses. And since that prompted the decision to name those two Derangers, we decided to identify Freakout too - while no one else shares that exact codename as of yet, it's not such an unusual name that it's unlikely to happen in the future.
Where we got the names? That varies depending on who names them. In this case, I did, and I like to have a reason for the names I assign, rather than just randomly picking something that might not fit. I don't normally explain those reasons, but since you asked: Janus is a disturbed artist, and his name is derived from an artist with mental issues; housewife Breakdown's first name comes from a well-known fictional housewife and her surname from that housewife's fictional husband; Heavy Metal rocker Freakout's three part name is inspired by real world heavy metal rocker(s). I'll leave figuring out the exact inspirations to those who want to try.
As for St. Elmo, see below...
While we're not certain St. Elmo is a personification, it's certainly one of the more likely possibilities. Providing him with a civilian name would have been refuting that option, and, given his powers and manner of his apparent demise, he's easily resurrected if a writer ever chooses to do so (perhaps unlikely, but more unlikely things have happened), which means narrowing down the scope of who or what St. Elmo really is wouldn't be helpful to said speculative future writer. Since there's no one else calling themselves St. Elmo within the Marvel universe, the need for a clarifier isn't there either. Hence, we elected not to add a real name for him.
