Alien Seer

The Alien Seer is an unnamed extraterrestrial seer who was responsible for giving Boros the prophecy about the worthy opponent he sought.

Appearance
The alien seer is an alien with eight eyes of varying sizes and multiple tentacles pertruding out of its mouth area.

Alien Conquerors Arc
Boros mentions the seer's prophecy to Saitama about finding a worthy opponent on Earth before they fight. However, the seer never reveals the identity of the worthy opponent to Boros.

The other Dark Matter Thieves believed the prophecy was a lie to drive them away on a wild goose chase. It is likely that the seer foresaw Boros's death, meaning this belief is at least partially true.

Supernatural Abilities
Clairvoyance: The seer prophesied that Boros would find a worthy opponent on a distant planet. However, it never stated the true identity of the opponent.
