Long live...

The whumpee, for whatever reason, is immortal.

The one who dies and comes back to life. The one who don't get (physically) hurt. The one with the long life expectancy. The one with the healing factor. The one who is reborn from time to time. The supernatural one.

The point is: eternal life is not pleasant.

 * As it is revealed at the OVAs (2/3), Zeno is "the one with the healing factor". At first he doesn't know what his power is... until he starts getting hurt. Once his king and companions find out that he can recover from pretty much any injury, he offers himself as a human shield and is denied. Lots of angst for outliving his loved ones, fighting alone at the battefield, and spending centuries alone.

Cursed


 * 1x10: Even after the effects of an poisoned arrow, struck by a couple swords and left for dead, Merlin (Gustaf Skarsgård) still wouldn't die. He moans about it when Nimue comes to his rescue, and during the escape, he is supported by both arms all the time.
