What would your dream spy gadget be?

If I were a spy, the Marauder's Map in the Harry Potter series would be a cool gadget. How fascinating would it be if I could see where my targets were? At the same time, I'd be able to avoid them (and also find mysterious shortcuts and new adventures). I bet this would help accomplish tasks more efficiently, and make things more interesting. To quote the famous motto: "I solemnly swear that I'm up to no good."

Captain America's super-hard, disc-shaped shield made from an experimental alloy of steel and vibranium. My reason is simple and the same as Captain America's vision: to save the world. Terrorist attacks are out of control these days, killing many innocent people. I'd figure out how the shield was made, manufacture thousands, and then send them to places targeted by terrorists, saving many lives in the process.

Being a spy is not easy, and sometimes even the greatest spies need a little help. An earpiece that can read people's minds would be of great value. Wouldn't it be amazing to know what others were thinking every second of the day? Imagine: no secrets, no lies. And with this earpiece, I'd be able to know what people were going to do before they did it. That's what makes a great spy, right? Hang on, I got it. You are thinking: absolutely. See, I can read your mind. So be careful - with this cool gadget, I'd be invincible.

If I were a spy, I would want a bulletproof umbrella that can also shoot tranquiliser or electric darts to put enemies out of action. Like in the movies, the weapon would pack a punch, and I'd give any attackers or bullies a shock without seriously injuring them, if you know what I mean.

They say the pen is mightier than the sword. A magic pen would let me draw anything I like, and the picture would become real. For example, I'd draw a clever key that would let me open all the doors.

An invisibility suit! I've always wanted something like Harry Potter's invisibility cloak. Imagine how fun it would be to stalk people and

listen in on conversations! It would definitely be a very cool experience.

I'd like a watch that would make you invisible. Imagine sneaking through enemy lines, amid blazing gunfire, then snatching a sandwich from a guard as he stares dumbfoundedly at his lunch disappearing into thin air. He'd raise the alarm, but nobody would be able to see you. As chaos ensued, you'd be able to destroy everything, steal secret files, and disappear into the cool, windy night. Seeing is believing, right? Hehe.

I'd want gum that would let me smooth talk my way out of any "sticky" situation.

Spying is often a low-key, under-the-radar, mysterious and thankless task. Therefore, I would like to have Ant-man's gadget to obtain secret information and accomplish missions. With the gadget, I'd be able to shrink to the size of an ant so that no one could find me as I went about my business. Also, I'd be able to communicate with ants, which would help me distract my enemies and gain more time to achieve my objectives.
