Narwhal-class submarine-Nautilus, Hull number SS-168.
I'm Nautilus, Narwhal-class submarine – Ah, um, not that "Captain Nemo." During that war, my friends shot at me by mistake, and I managed to do something incredible without realizing it... Overall, I think ended up being quite useful to everyone...
