An early experimental Zeon combat MS rival of the Zaku I developed by the Zimmad Company. It was fast, had a versatile array of weapons which included a 135mm anti-ship rifle and was perceived as vastly outperforming the Zaku I - except it was all propaganda: the suit was prone to overloading its engine and exploding at random, and it did so in multiple occasions despite endless attempts at fixing such horrible behavior, being deemed a total and utter failure.
However this problem was eventually solved and the Zudah was actually modernized and used in battle some time later by selected Zeon and Neo Zeon units in a limited capacity.
In Gundam GQuuuuuuX's final episode, one of the alternate timelines witnessed by Lalah depicted Char piloting a red Zudah. Due to the suit's aforementioned issues, viewers quickly joked that his death in that timeline had nothing to do with the Earth Federation Forces and all to do with him being set up to die from suit failure.
