Lancelot? Ah, "Knightmare" wouldn't be spelled with a K, would it? It seems like exactly the right kind of pun. I'm sorry, though, I'm afraid I don't know much about these from firsthand experience. Not ones that aren't autonomous, at least. Anyone actually piloting something like that strikes me as nothing short of terrifying, especially if it's armed.

It is very elegantly designed, though. Your friend and brother both have excellent taste.
