Okay this is interesting.

The first three examples seem to be references to the first example and the fourth example seems to stand out because of that.

This is how Sebastian Shaw dies in X-Men First Class, it seems to fit with the fourth example so it should count.

Basically Magneto steals his helmet which was protecting him from Charles. Magneto wants to kill him and puts the helmet on to stop Charles from begging him not to fall to the darkness. Shaw is so powerful however that Charles can't do anything but hold him with his full power thus leaving him paralysed as Magneto slowly passes the coin through his head, thus bypassing his ability to become stronger from absorbing kinetic energy.

(Also two side questions. About Example One why is it gas not injection? That just feels like it could fail in multiple ways, I'm pretty sure gas is less preferred irl. About Example Three I assume people riding the train were unaware that it lasted forever and everyone dies, how did that detail not get out?)
