Fantasy superheroes will expire as they are mere mortals, and the only thing guaranteed of life- is death.
The reality is that only Allah is the ever living, and what matters is the state in which a human being passes away in.
May Allah allow us to live entirely upon Islam, and pass away upon Imaan. And may He join us with the righteous true heroes, the Prophets, the Messengers, the Truthful, The Companions and the Righteous. Ameen.
