1,2. I like the concept quite a bit, as it adds realism and a new degree of ecology to the series. No ecosystem is free of competition between species, and some species just flat out hate others for their own reasons.

3. This is a tough choice, quite a few good ones on the list: competition for same niches, competition between differnt niches, predator-prey rivalries. Honestly, I'll have to go with the Gurenzeburu vs Highland predators rivalry. It's just so different from other rivalries: an herbivore defending it's bretheren from predators, that's something that isn't even seen often in nature. This also took me surprise, as I was unaware Gurenzeburu was an herbivore (especially looking at those teeth).

4. I'll have to say Diablos vs. Cpehadrome, for the same reason Cottonmouth255 said: the rivalry doesn't really have a basis between the two species, as they have completely seperate ecologies and don't seem to have a predator-prey basis.

5. I can imagine a rivalry existing between the precious raths (Gold ian, Silver los) and large herbivores that live in the same habitats as them (Duramboros, Gravios, etc). They seem to be very heavily built and seem perfectly adapted to hunting together against large herbivores, which are otherwise untouched by most other predators.

6. I've actually been workin on my own MH region lately, though I don't have any fleshed out rivalries yet, though I do have a predator-prey relationship between a spinosaur-like brute wyvern that fishes for the young of a species of snake wyvern in the desert regions, so it's possible the adult snake wyverns and the brute wyverns can have a rivalry between each other.

On a side note, what's the rivalry between Amatsu and Zinogre? Seems a tad foolish for a predator even like zinogre to be battling an elder dragon.
