25 most heartbreaking Arrowverse deaths of all-time

20. M’yrnn J’onzz

The arrival of J’onz’s father, M’yrnn, really changed up the dynamic on Supergirl as the Martian Manhunter discovered that he wasn’t the last-surviving Green Martian after all. It wasn’t exactly surprising that the pair’s relationship quickly became one of the show’s most endearing, as Carl Lumbly portrayed the character with a warmth that just radiated off the screen, and his chemistry with on-screen son, David Harewood, felt so natural.

It was heartbreaking when the character started suffering from Mars’ answer to dementia because, as we all know, one of a Martian’s greatest assets is their incredible minds. And this disease not only made him lose sight of the things he loved, it made him dangerous – something that made it even harder to see both him and his son go through that.

However, he was determined not to let the disease take him – and he succeeded, sacrificing himself by phasing into the earth itself and stopping Reign from destroying it. While this allowed him to die the heroic death that he wanted, it also allowed him to say goodbye to his son on his own terms.

“Be happy, my son,” he told J’onn with a warm smile before he sunk into the earth, leaving us all to watch in awe at his selflessness.

I’m not crying, you’re crying.
