Titles from the Mazinger Z series, either being sequels to the original anime or remakes/ reboots of it

These are the anime that appear in Super Robot Wars J for Game Boy Advance.

This is often considered one of, if not the best written Super Robot Wars game, and is a personal favourite of mine.

Anime featuring mainly traditionally animated, hand drawn robots made between the year 2000 and 2009. As CGI started being used in anime in this period, some mecha series started shifting towards CGI robots, I think this list would be really helpful.
