I don't play as many games as I would like people to believe, but the stick weilding bosses from Condemned: Criminal Origins were very strange indeed.
While his majesty Yahtzee made the very prompt-worthy statement that things become less scary once you explain them in his review of the second game, Bloodshot, these bosses were never explained in full, or at all in the sequel.
While it's likely that they were redesigned for the sequel and we weren't shown this, like pretty much all the other characters, I saw no real proof of this and can still fool myself into thinking that they're mostly unrelated.
Besides, me and my friends would always give them funny names like "Roger" or "Sprinkles."
