My headcanon is that instead of being blown up, King Sombra was subdued and set on the path of reformation like Discord.
Many years and many obsticles to overcome later,
He is no longer “King Sombra” but rather, “Prince” Sombra.
Continuing my headcanon, he eventually fell in love and married Princess Luna and helps with guarding the night.
