He's adopted.

The team discusses Loki on the helicarrier in a scene from Marvel's The Avengers.

Five years later:

“HE’S MY BROTHER!”
“Adopted.”

[zorohibiki]

defending loki and distancing himself from him at the same time is such a brotherly thing to do

[miren]

"An army...from outer space "
Steve looks so done with the 21st century😂

*"HE'S ADOPTED"* - Thor 2012

[BuffetPentagon]

"I love snakes, but Loki once turned himself into a snake and when i picked him up, he screamed 'it's me!' and stabbed me"

[malcolmsmith]

"He killed 80 people on two days"
"He's Adopted"

[damienloxely]

They *REALLY* gloss over the 80+ Loki killed...

[thegreatjedi]

2012:
Thor: "And he is my brother."
Natasha: "He killed 80 people in two days."
Thor: "He's adopted."

2017:
Loki: "I've never met this man in my life."
Thor: "He's my brother!"
Loki: "Adopted."

thor in ragnarok seems to has very different personality

[darthtroller]

Thor: Loki is beyond reason but he is from Asgard, and he's my brother
Widow: he swore on a Christian Minecraft server
Thor: he's adopted

*Avengers...*
~
Thor: And he’s my brother.

Black Widow: He killed 80 people in 2 days.

Thor: He’s adopted.
~
*Ragnarok...*

Thor: HE’S MY BROTHER

Loki: Adopted.

[chickennugget]

Heh when you love your brother then someone tells you how bad he fucked up

[Woobear]

I love how he defended Loki and at the same time how quickly he separates himself

[thehutch]

Funny how he kinda says “he’s adopted” as a suggestion, not a statement

[alicenthightower]

Ironically...Loki the adopted one has more in common with Frigga, Odin and even Hela who he just met...You sure Thor ain't the adopted one?

[jtyler]

Thor: Loki is beyond reason, but he is of Asgard and he is my brother
Black Widow: He listens to Justin Bieber
Thor: He's adopted

[ethanwelk]

Chris: He is beyond reason, but he is of Australia and my brother
Scarlet: He is engaged to Miley Cyrus
Chris: He's Adopted

[thenerdyoverthinker]

The comedic timing from Chris here is underrated.

[altair]

10 years later and Loki still adopted.

[pandoraarts]

Wow Thor, such a supportive brother you are 😂
