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.
When a supergiant core collapses, then there will probably be a supernova.

neutron star?
A star 8 time the mass of the Sun turns into a neutron star when it run out of fuel, become a supergiant, and undergo supernova explosion. After the explosion, a core remains. If the core is less than 3 Solar masses, it becomes a neutron star, or else it becomes a black hole.
What will form is a neutron star or a black hole. (Strictly speaking, it's a red supergiant that becomes a supernova.)
Antares

Yes, it is a red supergiant star.
A star that has exhausted the hydrogen in its core will become a red giant or supergiant.

Yes, Betelgeuse is a red supergiant star.
The easiest supergiant star to see is Betelgeuse, the bright red star at the shoulder of Orion the Hunter.
