Special Nemeses

[Skyblade]

So I received a special Belphegor from my Update Data today. He's level 99, and he's named Early Spring; Teddy. This goes along with the level 99 Mammon I've found called Be Mine; White Fox. I also have a level 99 Beelzebub, but I don't know if it has a special name, since it has a Japanese name to it.

The fights are overall really cool, and I like that there are some good rewards (both items and Genome Skills) to get from the Nemeses fights. But after the nearly hour-long fight to get through the level 80 Belphegor yesterday (Hard Mode), I'm a bit hesitant to take on this new one, even though I think the rewards might be better (and possibly there might even be an item to steal).

Have any of you guys found any of the special Nemeses fights yet? And, if so, are you saving them to send, or fighting them? What do you think of the Nemeses fights overall? What strategies and setup do you use for each one?
