Cinema monsters (in order of which I can remember)
Alien (created by Hans Rudolf "Ruedi" Giger a swiss artist) it happen as the producer's of the movies (including Ridley Scott, saw his necromance series of paintings and brought him to design the monster for the 1979 movie.
The second monster is the Rancor from Star Wars, The Return of the Jedi. Living in Jabba's pit it is killed by Luke Skywalker. Drew by Joe Johnston and created and made a puppet by ILM for the 1983 movie.
The Predator
"Created by brothers Jim and John Thomas, the Predators are depicted as large, sapient and sentient humanoid creatures who possess advanced technology, such as active camouflage and energy weapons, and are capable of interstellar travel."
Taken from the wikipedia page on The Predator. It was designed by Stan Winston allegedly with input from James Cameron.
Godzilla, known in Japan as Gojira first appeared in the 1954 movie of the same name. It has been in 28 movies, including one made in the US. Godzilla is a nuclear accident lizard that has incredible powers. It is the blueprint from which all lizard monsters are created from.
Medusa from Clash of the Titans. (original). Designed by Ray Harryhausen, this 1981 movie and one of the last stop motion animation movies created a very scary nemesis for Perseus.
Why I didn't add King Kong or the T-Rex / Velociraptors from Jurassic park?
Since they are based on real creatures they are not really monsters just super sized animals.
Now Animation monsters
The Witch from Snow White. The scariest witch on movies, bar none.
