Amy meets the black knight

One day, Amy went to a faire where she met another disabled person. The Black Knight from Monty Python and the Holy Grail.

I did not watch the whole movie but I did see the black knight scene. It was hilariously funny. The Black is in fact "invincible". I first heard of him in the Ultimate Showdown of Ultimate Destiny

Amy was born from a world where everyone had no arms. The Black Knight is an amputee which were chopped off by the king.
