The statue of Nightcrawler in the Dominator castle depicts him as a humanoid sneaking around with a dagger.
Nightcrawler was a master infiltrator and assasin. It is believed that the Vashta Na’rada was started by him or at least in his honor. He is always depicted wielding a dagger or two, usually while cloaked.
