"So, I lost the race," said The Other. "But I will not leave! Thanos WILL have the Infinity Gauntlet by the end of the day! If you won't give it to me, I'll take it by force!"

The Other ran behind Rainbow Dash, grabbed her tail, and slammed her on the ground. As he was lifting her up again, she kicked his arm, causing him to release her. She flew circles around him, but he was able to follow her every movement and smack her to the ground. The Other walked over to Rainbow Dash.

"Your wings look delicious. I shall barbecue them and serve them to Thanos."

"Why is it always my wings?" said Rainbow Dash, and she flew up to The Other and kicked him in the face, knocking him on his back. Rainbow flew into the air and directly down at The Other, but using his speed he simultaneously dodged and got into a standing position, causing Rainbow's front hooves to smash the ground.

They started to fistfight, too fast for anypony to follow, if there had been any ponies in the area.

The Other grabbed Rainbow's left wing and tried to pull it off. Rainbow responded by whipping The Other in the face with her tail, causing him to let go of her wing, and she quickly kicked him to the ground.

Getting back to his feet, The Other shot an energy blast at Rainbow Dash, but she casually dodged it. The Other shot rapid fire energy balls at her, but she dodged each one, kicking or tailwhipping a few back at him. One of them hit him, weakening him a bit.

Rainbow Dash flew at The Other, who ran behind her and tried to bite her wing. Rainbow moved slightly causing him to bite her tail instead. Rainbow immediately flew into the air, as high as she could, so that The Other wouldn't dare let go for fear of falling to his death.

With both hooves in front of her, Rainbow Dash flew as fast as she could, and once again, did the Sonic Rainboom, creating a rainbow shockwave as she flew faster than the speed of sound, leaving a rainbow trail. She flew circles around Equestria, making The Other dizzy, for even he did not know speed like this.

As Rainbow reached a point above an empty field at Unicorn Range, The Other let go of her tail. However, because Rainbow had unintentionally gotten lower to the ground, The Other did not have a long way to fall. He landed on the grass, and lay, dazed. He got to his feet, looking around for Rainbow Dash.

She was directly above him, approaching at incredible speed.

The Other looked up just as Rainbow crashed into him.

BOOM!

There was a rainbow mushroom cloud explosion where Rainbow Dash had collided with The Other. When the smoke cleared, Rainbow Dash was standing in a small crater. There was not a shred left of The Other.

Thanos sensed the life force of his servant vanish.

"Fine. I'll do it myself.

Just as Rainbow Dash finished telling her friends about her victory over The Other, Thanos appeared.

"I am Thanos, ruler of the universe!" he said. "I am not a weakling like my servant was. Give me the Infinity Gauntlet or I will bathe the starways in your blood!"

"Rainbow Power, now!" said Twilight.

The Mane 6 activated Rainbow Power.

"What is this?" said Thanos. "Your power... it's infinity! Is this... what I thought was the Infinity Gaunt..."

The ponies blasted Thanos with their rainbow. Thanos howled in utter defeat as he was undone in a magnificent flash of rainbow.

Thanos materialized in a cage in another glowing cell in Tartarus, and a screen of G3 started playing.

"GET ME OUT OF HERE!" said Thanos, though he knew this was where he'd spend eternity.

As with my Chrysalis story, no offense intended toward anyone who likes G3.
