Big Daddy Nautilus
(I have no doubt this has been suggested before)
I played a game as Varus with my glorious Nautilus support... At some point, Zed came after me and killed me in two seconds. Later that game, Zed tried that again, but Nautilus was hiding nearby and was able to save me, and I managed to kill Zed with his help. My response in all chat was, "Not this time. I got my big daddy with me." It seemed like an appropriate thing to say.
