The head captain had the strongest fire type sword (even though I'm not sure about the identity of his Zanpakuto, I think there was something else going on there), so honestly, I hope Engetsu's shikai isn't (or wasn't) a fire type. It'd be cooler if Engetsu was the strongest of its own type, or at least stronger than all the current ones.

I still think Zangetsu is spiritually related to Engetsu; nothing has proven the possibility otherwise.
