1) Maybe, as Lasatar said, could be a Monster with the same role of Lao/Gaoren/Mohrans or alternatively the low rank final boss (if there's still low/high rank).

2) Now the meaning of Flagship Monster isn't completely defined, I mean, MD Diablos as been officially declared as Co-Flagship with Valphalk in MHXX but it doesn't appear in the boxart of MHXX. Also, while Rathalos appears in the Boxart of MHW, it wasn't mentioned by Capcom that he is the flagship of MHW IIRC.
