Loki: *Throws a knife at Star Lord*
Star Lord: *Dodges, but the knife keeps following him*

Captain America: *Kneels down, and looks at his shield* How is that possible?

Thanos: I have the ability to bend the universe any way I want to!
Silver Surfer: Now!
*Motorcycle screeching can be heard*

Captain America: Me, and this shield went through everything. I raised it since it was little. *Enters rage mode* Noboby messes with my shield, and gets away with it!! *Punches Thanos*

I'm not sure if the rage mode is real, or not. I thought it would be funny since Cap lost his shield

Thanos: *Feels nothing, and throws Captain America*
*Suddenly, the Ghost Rider arrives at the scene*
Thanos: *Sees the Ghost Rider*
Ghost: Rider: You...

Princess Celestia: GAH! *Falls*
Adam Warlock: *Warps Thanos out of existence*

Hawkeye: Celestia? Can you hear me?

She Hulk: Celestia didn't make it...

Rarity: Wuuutt??? What happened?

Thor: Thanos murdered her.

Rarity: Of all the worst things that could happen, this is The! WORST! POSSIBLE THING! Except for that one time I got caught wearing green.

Iron Man: Now who will lead Equestria?
