"ANCIENTS/ELDERS: The greatest Yautja that have ever lived, they have survived a thousand hunts. They have hunted so much that they look for other means of sport. Consequently, they are more compassionate and disciplined than most other Yautja. Many have learned new fighting techniques over the ages. For example, one "Ancient" who had hunted in 16th century Japan learned "Hira Baraki," or two-sword combat, continues to use it today, and has two custom swords. These represent less than 1% of the entire population."
Do I need to say more?
Also, physical abilities:
"Thermographic vision to 2000'. See the invisible through thermographic vision.
They breathe 1% more oxygen, and 4% more nitrogen than humans. They can adapt to earth's natural gasses, but it could only last for 1 week at the most. If Dr Bergstrom is correct on her theory (Predator: Homeworld), this could be because this is what the atmosphere was like on Earth millions of years ago.
They can hold their breath for several minutes.
Can jump up to three times their height, and can fall ten times their height and land on their feet.
Predators can imitate the speech/sounds of other species, but do not necessarily understand the meaning of what they say. They often imitate voices of the species they are hunting in order to fool or terrify their prey. They do pick up languages quickly, however without formally studying the language as a secondary skill.
They can hear a whisper up to 50 feet away.
Impervious to heat (boiling water gets uncomfortable after 5 minutes), invulnerable to electricity and to radiation.
They are fast enough to dodge bullets, if they see them coming and can, because of their tough hides, shrug off most small-calliber bullets.
They have no use for magic, and find it disdainful. Only cowards would resort to parlor tricks.
Chances of a psionic Yautja are rare, but those that exist are unbelievably powerful, so much that they'll not hunt with normal Yautja. A telepathic Yautja, DNA-modified by the Dominators into a meta-Yautja, fought alongside other "meta-Yautja". They hunted only the metahumans of the JLA.
The Yautja are larger and taller than adult humans, standing at least seven feet (2-2.5 meters) tall but often much taller.
An average Yautja weighs between 250-350 lb., most of this is pure muscle. The Yautja have very little body fat due to their predatory lifestyle and diet.
As far as environment, it appears that the Yautja prefer hot, humid conditions with an atmosphere rich in nitrogen.
Not only could they press up against metal heated to 120 degrees Celsius without being burned ... they seemed to relish the heat." (From Predator: Cold War TPB)"
Predator is more durable and most likely faster then Cap. Cap MIGHT be stronger, but probably not by much. And an Elder Predator is muchmuchmuchmuchmuch more experienced and more skilled fighter then Cap.
Although, the Elder just might leave Cap alive after the fight...
"The Yautja ELDER class are more reasonable. Elders are the greatest Yautja that have ever lived - having survived a thousand hunts - and they consider honoured fighters of other species as respected as their own kin. Elders have often let warriors of other species live after they have proven themselves honoured warriors. This usually only occurs if the subject has killed a Predator or fought alongside in battle. There is also a common practice in these cases to maintain honour, by exchange of trophies on both sides."
