It may become a White Dwarf.
Initially it is a question of how much material was present in the disk that collapsed to form the star. Subsequently, it may be affected by collisions with nearby stars.
A massive collapsed star is a dead star.
A Neutron Star
Neutron Star
What the core of the star will become is dependent of the mass of the supergiant star. Stars between about 3 and 10 solar masses will generally become neutron stars. Stars above 10 solar masses generally become black holes.
A collapsed star is a term used to describe a "dead" star, which is a star that has come to the end of its lifetime and just collapses on itself. A black hole

That description may refer to any of the end-phases in the lifetime of a star: a white dwarf; a neutron star; or a black hole.
The dead star can conclude in a couple of ways. If the star was a smaller star, it will become what is known as a brown or black dwarf star. If the star was of substantial size, however, it will become a black hole. This means the star has collapsed into itself, and no longer occupies any space.
No, it's a hypergiant. A dead star is a collapsed star - not a giant in size (the mass may be considerable, though).
An older star that has become small is called a white dwarf. White dwarfs are the remnants of low to medium mass stars that have exhausted their nuclear fuel and collapsed to a very dense state. They are very hot and small compared to their original size as a main sequence star.
It seems you are referring not to any collapsed star, but a black hole. The "event horizon" is the area from which nothing can escape.
