Your iPhone case intends to protect your device and also makes it look fashionable whenever you visit a coffee shop or a mall. But what if your iPhone case does something more for you such as defend you from robbers, maniacs and perverts using a built in Pepper Spray?

iPhone cases should go up to the next level and allow users to place tools, attachments and customisations. Here are 5 unique, weirdest and wildest iPhone case designs.

1. iPepper Spray
If Siri cannot alert your surroundings enough when you are about to lose your iPhone, why not using a case with pepper spray to subdue the attacker? The design looks like any other case you can find except for a little canister attached at the back and when you press it at the side, boom! A stinging spray spits out, temporarily subduing the attacker which enough for you to escape.

2. iKnucks
For the male version of self-defence, how about the iKnucks? Not only it looks very cool but also a weapon you can use to defend yourself in case you're going to be mugged. Remember, accessories such as this should only be used for defence not for beating someone else.

3. iStun
A quick powerful defence line compared to iPepper Spray and iKnucks would be the iStun. The design prototype provides protection to your device and also generates up to 650,000 volts when the built-in stun gun is used. Ever wonder if iPhone's battery can really knockout one person?

4. iPhoneography
In case you are the witness of a crime or event, use Orbit Pro's iPhoneography case with built-in lenses. It is a meticulous engineering which allows the user to capture photos using Peripheral Motion Lock Technology that rotates the case through four different optical lenses - 180 degree, 2x telephoto, 67x wide angle and macro lens.

5. iFlash
Use the light emitting power of the iFlash to alert authorities during emergency where is more effective than sound. Kickstarter Project uses LED Flash Alert feature which generation illumination around the edges of the phone. Normally used for calls, texts and push notifications.
