Let's start off with what the thing is:
-A parasitic cellular organism capable of absorbing any kind of biological matter and expanding itself by "eating" that biomass.
-Capable of advanced cellular manipulation to mimic other lifeforms that it has "eaten". (One of the characters described it as a "chameleon")
-Capable of reproduction by splitting like an amoeba or an earthworm. If you cut the thing in half, now you have two things. This makes it pretty much impervious to physical attacks. (Unknown if one thing can absorb another after a split)
-The only way to truly kill it is through complete cellular destruction (Fire, chemicals, or energy... Unknown if radiation effects it)
-Intelligence is based on size, where a thing the size of a finger has little more than animal intelligence, while a thing a little bit bigger than a human was implied to be trying to build a space ship.
The thing's only downside is that it requires physical contact to spread itself, but I can see that changing if it eats something capable of shooting biological ranged attacks. However, it seems that the thing doesn't like fighting, and only kills in self-defense, it seems much more content to use it's mimicry instincts to hide itself rather than try to murder or "eat" everything in sight. Although, that could just be the chosen strategy of the thing in the very limited situation in the book/movie.
The thing would absolutely devour an entire tyranid hive fleet if it got the chance and become insanely powerful because for the thing bigger = more intelligent. If the hive mind was smart enough to catch on and kill the thing before it got too far it might have a chance, but tyranids (even bioships) are all about melee weapons for the most part which is a distinct disadvantage against the thing.
