There's just absolutely nothing special about Brachy other than the fact that he's the only common new monster in the game, which is clearly why Japan put him all over the promotional material and the cover.

Once you replace him with something else, in this case Azure Rathalos, and make that the poster boy and featured cover art monster, Brachydios just ends up being really insignificant within the context of the game itself, even moreso than Nargacuga was in Unite, which we all complained about. If you took Lagiacrus off the cover and posters, he'd still be the central focus of the story and you would become far more acquainted with him through NPCs than any other monster in the game, which is how a flagship is always treated (Tigrex, Rathalos, Zinogre, etc)

In MH3U, the only mention anyone even makes of Brachydios is the Argosy captain, who is basically just like "Yeah hey I saw this monster in the volcano, go kill it." and then after that he just becomes another mob like anything else besides Lagiacrus and Ceadeus.
