The Thing Vs. The Blob Two terrifying aliens with basically the same bit. They absorb stuff. In the case of The Thing, the alien absorbs and copies a living creature, reproducing it's genetic make-up.
Intelligence is extremely high and it's main goal seems to be eating whilst remaining undetected.
In the case of the Blob, the alien absorbs a living creature and adds it to mass. Between the two of them, they've already munched the entire population of a small Nebraska town. The Thing has tremendous accumulated intelligence. 50's Blob or 80's Blob wouldn't matter. First things first.
