User blog comment:Lord Loss/Monster Hunter Theory... Blog/@comment-3211692-20121205202132/@comment-5460283-20121206004825

This is a very good theory, but i'm going to go out on more of a limb saying it wasn't a Rath (ian or los) in the first place but not a mimic either but what you said, a species that has taken components from other major predatory monsters.

Here's my list:

1) Rathian basic apperance with back/red coloration.

2) Rathalos longer end-tail spike

3) Some Espinas fire-breathing stances

4) Doragyurosu lightning -> wing spikes (which may not be spikes from the wing but poison barbes from the back)

5) Strength that compares with something like a Diablos or Gravios

6) A new flame sac chemical that comes from ????.

7) A flame sac developed to shoot a beam like a Gravios.

8) The ability to shoot an armor down gas like a Uragaan just not like fire fart or speepy fart.

And I could fairly saw that the origional monster was a true flying wyvern like its outward appearance,some of the most powerful true flying wyverns the Rath family.
