On the battlefield, the Avengers were locked in a fierce battle. Just as Thanos was about to win, suddenly, a loud bang was heard in the sky, and a huge warship that blotted out the sun appeared above everyone's heads. A man stepped out of the open hatch of the warship.

Who are you?!

Thanos sensed unease and shouted loudly.

"You ask who I am?"

The man had an air of arrogance and disdain for the world.

Just as the remaining clones were buried by Otto's men, the music from Plants vs. Zombies began to play, and a hand emerged from the ground. "Honkai Impact 3, welcome your king!"

"Even if I, Lina, am poisoned to death by Honkai energy, die outside, or be used as a guinea pig by Mebius, I will never become a beautiful girl."

Soon after, surrounded by countless beautiful girls, Lina said with a silly grin, "Wow, it smells amazing."
