Tigrex, a flagship monster in MHF2, seems not to be appear in this game. While Lagia and Narga, the other flagship monsters, appears in the game and also got a new rare species. Looks like Tigrex would only be appeared in the PSP versions. So thats maybe a hint, "IF" Capcom release the MHP3rdG in the future, they may include Tigrex, and it may also get a new rare species.
