Need anime opening crossovers where characters from one anime are drawn over the opening to another anime. Here's some examples:

https://www.youtube.com/watch?v=AuTR2OaeidU (Urusei Yatsura opening, Kaiji characters)
https://www.youtube.com/watch?v=hputLPRiPDk (Revolutionary Girl Utena opening, Lupin characters)
https://www.youtube.com/watch?v=xi5oZqH1pjc (Haruhi Suzumiya opening, Jojo characters)
https://www.youtube.com/watch?v=yxSIH_KIICk (Baccano opening, Yugioh characters)
https://www.youtube.com/watch?v=XxrBMp6dpxo (Medabots opening, Hetalia characters)

If possible can both be anime related and not just anime clips being pasted onto an anime opening. I've searched about NND a lot and found a few but it's hard without knowing Japanese, so any from there are also okay.

Thanks.
