A star that is over 5 times the size of our Sun is classified as a massive star. After spending a period of time in the main sequence phase, where it fuses hydrogen into helium in its core, it will eventually exhaust the hydrogen fuel in its core.
The next phase of the life of such a massive star will be the **red supergiant phase**. During this phase, the star will start to undergo hydrogen shell burning around an inert helium core, causing it to expand significantly and cool, leading to the characteristic red color.
Following the red supergiant phase, the fate of the star is to ultimately undergo a supernova explosion, resulting in either a neutron star or a black hole, depending on its mass after the explosion.
