Could this be seen as a potential example of how Ridley would take on things bigger than him?
((This is gonna be long'ish))
The first segment of this video demonstrates exactly how I would expect a highly intelligent, fragile creature (such as a dragon, wyvern, or Ridley himself) not to behave. It sensed a threat from a point of safety and a point of being potentially hidden. It had an opportunity here to hide. It did not. Rather than remain on its perch and potentially avoid detection, the wyvern roared at it, giving away both its position and its intentions as an adversary and aggressor.
The wyvern then engages what appears to be a much larger tyrannosaurus'like creature in direct combat. It's using its claws and jaw, which seem unequipped to confront the tyrannosaurus head-on. The front is also the place where the tyrannosaurus is most capable of defending itself against. This is well-demonstrated, as not far into the engagement, the wyvern is immediately grabbed and thrashed by its neck as punishment for such a reckless attack on the worst possible angle to approach this adversary. Had the creature not approached the scenario so recklessly, it would not have been in such a position to be, quite literally, grabbed by its neck and thrashed around like a dog's chew toy. That would have immediately killed such a fragile creature. After all, dragons or wyverns, if one were to make an argument for their existence, would likely have a physiology that would be put under tremendous stress in such a scene. Ripped wings, broken phalanges (finger bones, basically wing bones), and a broken neck would likely occur from this totally avoidable scenario for the wyvern.
I would, honestly, assume the creature to be dead at this point, though it was not due to story progression in the clip, after all, we had to have the rock smashed to reveal the hiding woman so it somehow survives.
At around 1:40, the wyvern appears to possess some sort of acoustic attack. It is ultimately able to inflict a potentially heavy blow with this attack, but the tyrannosaurus has not been wounded to the point where it's unable to stand up. The video cuts out here with the wyvern on the ground standing against the tyrannosaurus, putting itself again at tremendous risk and removing its gift of flight from the equation for no reason other than to roar and look intimidating. I imagine if the clip continued and logical battle were to follow, the wyvern would be, again, grabbed, thrashed, and killed.
I have many questions, and given Ridley is such an intelligent, sapient villain, I would suspect he would have many as well such as:
Why should I reveal my place of hiding?
Why should I reveal my intentions as an aggressor?
Why should I fight this creature in the first place?
Should I want to engage this creature, why shouldn't I hover well out of range of any of its attacks and use my acoustic attack on it repeatedly until it is in a weak enough state such that it poses me no threat?
Should I fight it at all, or stalk it, waiting for a more opportune moment?
Should my acoustical attack be ultimately ineffective, how should I approach such a creature? Clearly I want to avoid its big, toothy, pointy mouth of doom.
The wyvern has every point to make a decision here to keep itself alive, and it was reckless. I don't picture Ridley being this reckless (well, unless he's serving as a boss for Samus and needs to die in a battle area for gameplay's sake).
Bah, why are Dragons and Wyverns always so stupid? They could do whatevery they want, but in every game they choose to just die totally avoidable deaths without any practice of tactic in their approach to a scene. In so many games they can talk, they can think, reason, plan, ponder, and can sometimes even form societies, yet as soon as a battle breaks out it's "raaaaaaaaaawr rawr let's go face tank everything and die, totally ignoring my superior mobility, ability to fly, and ability to hit with ranged attacks such as fire breath"
