I nominate the "crownie" golden knight from the fantasy era. That gold armor is unbeatable, plus he has a gray beard, so must have won a great many encounters with those nasty skellies and other enemies to survive to that age! (Image by Agent Fuse posted in Brickipedia)
A good healthy debate ensues.
I object! That golden knight is a "pansy" in my castle world. What self respecting Knight wears gold?!?! It is a soft metal!!!!
It isn't going to stop any weapon coming at him. To look pretty I say. To brag and to show off. In other words absolutely no knight I want defending me. No thanks. Now if you are going to tell me he is in his "party" attire, well I still say no thank you. What kind of knight wastes his money on gold armor when he can spend it on better weapons, armor and horses?
Give me a good old fashion Black Falcon or a Shadow Knight and I am a happy and well defended lady.
