By "secret monsters", are we talking new addidions besides E4, like Hororohoruru, or are we talking returnees? Because there are a few monsters I can think of that could be potential "returnees", many of which are 6* bosses, though.

1. Lunastra, Didn't everyone think this would show up in 4U but didn't. And don't start on how it would be the same as Teo, because since Teo got a revamp (blast), there's no reason to say that Luna can't get extra attacks as well. (P.S. If Luna returns Tower is all but comfirmed)

2. Ceanataur, we got blangos. didn't we, well with the return of the volcano (lack of hollow), this is a pretty likely cantidate, unless it's Lavasioth (wait, if Lavasioth returns, then could other frontier monsters get in as well... SHANTIEN CONFIRMED... not realy)

3. Lao-shan Lung, It's all related to the story of Kokoto, so why not return alongside.

4. Shen Gaoren, While not nessecerally related to any story, the town did return in 4U as the battlequarters, and the new stuff would be perfect for the Shen fight.

5. Amatsu, Just like Lao, it's related to Yukumo.

6. Yama, while not related to anything, it needs to return big time.

While not all of these will make it,if at least one does, I will be very happy.
