[[WMG: Sayaka Yumi from ''MazingerZ'' showed up in ''UFORoboGrendizer''.]]

Sayaka was supposed to show up in the series and having a role active, but she was replaced by Maria Grace Fleed cause ExecutiveMeddling. However, the prototypical {{Tsundere}} lead would get NOTHING from that. Shortly after Maria's first appearance, she kidnapped the girl and spent the whole remainder series impersonating her.
* If Sayaka has to fight against Maria (basically a tsundere vs tsundere fight) for the love of Kouji (as we saw many times in some ''VideoGame/SuperRobotWars'' games, and also in some stories and parodies), you can bet safely your ten bucks that Sayaka will kick the little bitch redhead ass for good...
