Not true. A generic villain is one that fits way too comfortably in the villain archetype and doesn't try to challenge it at all. Read up on your Vladimir Propp theory buddy.
Joker for example is not a generic villain. He doesn't have any real goal as such, just the pleasure that comes with 'anarchy'. It's a simple goal but that doesn't make him generic, because the goal and the motivation is heavily explored in countless storylines and comics.
common overlap is the God-Mode Sue, with a ridiculous power level, forcing the heroes to hold the Idiot Ball, and/or requiring Deus ex Machina in order for the protagonists to stand a chance of defeating them. This is the type that generally shows up in canon. It can overlap with other types, such as Jerk Sue, as well, but it never overlaps with Purity Sue (although they might become one after the Heel-Face Turn, once the plot forgets everything evil about them).
Generic goals are: 'ambiguous world peace', money, fame, power of some kind
Hell we never saw Madara's connection to the Tsuki no Me, we never saw why THIS would be his logical solution or would be his perfect way out of reality. If anything Madara is a king, he seems like someone strongly grounded in reality. He had this Tsuki no Me plan half-heartedly assigned to him because that was the Akatsuki's and obito's goal.
