The Lion and Lord Unicorn are characters who appeared in Way To Wonderland TV Special. They are from Through The Looking-Glass, and What Alice Found There.
They are fighting for the crown who belongs to the White King, which, given that they are on the White side as well, makes their rivalry all the more absurd.
The Lion is slow and rather stupid, although clearly the better fighter. The Unicorn is a educated gentleman.
The Unicorn is a human-like unicorn, who wears formal clothes in blue, white and black colors.
They seem to be friends of the Queen of Hearts once they were invited to her birthday party.
