Tatsumaki vs. Ancient King

Tatsumaki vs. Ancient King is a short-lived battle that takes place between S-Class hero Tatsumaki and the mysterious being Ancient King.

Prelude
The Ancient King awakens after 300,000,000 years of slumber. Now that the other "kings" have died, he has awoken to take over the land. Military forces are sent to stop him, but he is left unharmed. The Hero Association deploys Tatsumaki to deal with the Ancient King.

Battle
As Tatsumaki lands in front of the monster, her phone began to rang. Albeit careless and talking on the phone, she orders the Ancient King to be quiet, as he was introducing himself. Ancient King shortly converses with her and insult her size. He then tries to stomp her, but she managed to fly away. Tatsumaki then swiftly takes care of Ancient King by bringing down a meteor to smash down on the monster, killing him.

Aftermath
Tatsumaki is left without trouble and Ancient King is crushed by the meteor, killing him.

Trivia

 * The animation team misinterpreted ONE’s intentions when animating the Ancient King fight. ONE only wanted Tatsumaki to drop a big boulder on Ancient King. Before the boulder hits him, Ancient King has a flashback of the meteor that destroyed his race eons ago and starts to scream. She was not supposed to pull a meteor from space. The meteor scene was supposed to be flashback only. If she could do that, she should be able to bring down Boros' ship without difficulty according to Murata.
