What is the most likely fate of a 25 solar mass Main Sequence star?

A star of 25 solar masses is most likely going to die in a supernova explosion which will throw half or more of its mass into space, and the remaining mass will become a black hole or neutron star.

Please note that since your body is made of carbon and other heavier elements such as iron, the atoms that are YOU have already been through a supernova explosion and were expelled from a dying star long, long ago.
