5. Bob 'The Brain' Newby, 'Stranger Things'
Ugh, why did this have to happen? Being the great man that he is, Bob sacrificed his life to save everyone else after the Hawkins Lab went into lockdown. Bob volunteered to go down to the electricity vault to monitor the lights and open the locked doors. After getting everyone else out safely, Bob barely made it to the entrance when the demo-dogs broke through the doors and ravaged him to death.
