cannot remember the name of this anime

Okay I am watching the Sousei no Aquarion again and I keep remembering like images from a similar anime I watched where the main character was kind of like apollo in being kind of wild and animal-like. In the beginning of the anime this character is put in a cage by the people he ends up living with.

Which era would this anime from? 60's, 70's, 80's, 90's or present?

Im not too sure but I think it was early 2000s.

Edit: Actually it was 2009-2010 according to wiki and anime-planet, the name is Isekai no Seikishi Monogatari.
