I'm trying to add a bit of story to this riddle/puzzle, so blame me for trying! I hope you like it, might be a bit rough at first, it's the first time I'm doing this myself. I enjoyed making it so good luck!

Background story:

You play a new character, whoever you want to be, but a superhero! You are a new recruit to the Avengers. Director Fury just found out his CORE is missing. All of the Avenger-team members are missing, missing as in on vacation or on a mission. As you are a new member of the team since today you are going to have to help Fury with this problem.

At the Avengers Headquarters

Director Fury calls you to his office and so it begins:

Fury: Hello new avenger, I'm director Fury.

You: Hello director Fury.

Fury: Come with me, it's urgent. This will be your first mission.

You walk to an office nearby where all camera footage is being kept.

Fury: The CORE has been stolen by one of our avengers. I believe he's working with Loki.

You: Is he still kept captive?

Fury: Yes, he's still in our dungeon. The thief didn't have much time to free Loki. I had a chat with Loki and he confirmed it's one of our avengers, sadly I believe him. Here's the footage of me chatting with Loki.

And so he shows you the video.

Fury: What is so important right now that you have to tell me?!

Loki: But Fury, don't be so mad, I know your CORE is missing...

Fury: How would you know that?

Loki: It was my plan after all, only the thief who stole your CORE betrayed me.

Fury: Why would I believe you. And if so tell me who did it!

Loki: Well, ... one of your Avengers. he said with an evil grin

Fury: I don't have time to play games Loki, tell me.

Loki: Yet the thief did not free me, I still prefer him or her having the CORE over you. You don't like games Fury? Let's play one.

Fury: I don't have time for this...

Loki: Destruction is what I'm after. Remember this Fury ' +8+15-18-18+2-3+6-5+5-1-11 ' got it? Enjoy playing the game ha ha ha ha ... .

Director Fury addresses you once more.

Fury: Son, as I don't have time to play games, you have to figure out what he means.

You: I will do my best. Do you have any idea what these numbers mean?

Fury: If I did I wouldn't ask you. You better figure it out!

So this will be your first mission. Figure out which Avenger stole the CORE.
Enjoy the game!

Avengers Assemble!

    $\begingroup$ I have an idea that almost works but it requires the -15 to be +15 :( $\endgroup$

    $\begingroup$ Are we sure Director Fury didn't steal the CORE and all of this isn't smoke and mirrors? $\endgroup$ Commented May 4, 2016 at 16:46

The thief is

Clint Barton (Hawkeye)


"Destruction is what I'm after"
We have to find the letters after "DESTRUCTION" using the shift "+8+15-18-18+2-3+6-5+5-1-11"
DESTRUCTION = 4 5 19 20 18 21 3 20 9 15 14
If you apply the shift modulo 26 you get these letters : LTABTRIONNC
You can re-arrange the letters to find CLINT BARTON

    $\begingroup$ I got as far as the shift, but was looking for the hero name, not the real name ... nicely done! $\endgroup$

My guess is:

Captain America


If you add all the numbers the addition is -50 and there are 50 stars on the flag of America. Hence the answer could be Captain America.
Don't know why the "-" sign

  • $\begingroup$ I guess it's a coincidence that it adds up to -50 haha. Nice theory though. That would have been a bit to easy wouldn't it? :) $\endgroup$

I guess it is not the right answer, but as it is tagged as lateral-thinking, I try :

Loki lies and is the thief : if the told Avenger had to steal the CORE and then deliver Loki, but finally didn't come to deliver him, how could Loki know the Avenger has successfully stolen the CORE ?

  • $\begingroup$ It's not Loki :( there is some math you have to do. Loki worked with the thief but he betrayed him :( $\endgroup$

The thief is

Clint Barton, a.k.a Hawkeye. From a character point of view it would be easy for Loki to get into his head, as he has done so once already, but the series of numbers is a code for a shift cipher. Since Loki says he is after 'destruction,' that's the word you want to apply the cipher to. You have to shift all the letters over, and then you'll get another series of letters. Then you just have to take those letters and look for the letters making up the name of one of the Avengers. You end up with Clint Barton.
