Totally the wrong timeline to have scientist tamper with a captured predator...
- Human technology at this point could never shoot down a predator ship.
- Predator spaceship, ( especially those with dangerous cargo ) would have fail safes in place to prevent a crash.
- mixing of various alien DNA into one body is IMPOSSIBLE, now I know, most people have probably never read up on genetics... but there is a reason why humans and chimpanzees cannot have a baby,,, despite being 99.8% identical. so the very idea of harvesting alien DNA from all over the galaxy and combine them is ludicrous... because each individual sample has evolved and depends on the nutrition, chemicals, gravity and so forth that was indicative of its planet/ homeworld... so when you combine, to let us say,,, alien DNA or tissue that needs sulphur in order to propagate itself ( cell divisions ) but is highly susceptible to oxygen... well you could never fit that organ or tissue with tissue that needs oxygen, but is highly susceptible to sulphur... if you put together a body of various components that each depend on a personal need... well your asking for tumors, mutations in the form of sickness, tissue rejection... ( hell we humans can't even transplant human to human organs, without risking rejection ) so... hybrids... not a f**king chance in hell... you go to a planet with different gravities and elements with a body made from a billion different things... you'll be ripped apart by your own cells, you'd be poisoned and worse... - at best a hybrid can be a creature that is mainly one creature, 99;8% but uses the organs or tissue of another in order to better survive in that environment... 0.02% but you can only ever be or have use of it, in that environment... hence a hybrid is still nearely a pure bred... and NOT some wildly mutated beast with near super powers...
