What happens to Super Red Giants?

-When the Fuel runs out to Fuse, then it'll cause a Massive Scene pretty much -No more Force from the Core will mean Gravity will start up a Gravitational Collapse which will lead to a Supernova -Then, the Leftovers of the Super Red Giant will be a Neutron Star - a Very Dense Core, or a Blackhole if its that Dense Enough. Blackholes, simply are a Stupid Stupid Densely Point which Light can not Escape.
