Picture of Last minute Doctor Octopus costume
Last year my kids insisted on store bought Halloween costumes. "OK" I said, "but you'll be sorry when you see how cool my homemade Doctor Octopus costume is". Of course, I didn't have any such costume. The kids thought I was full of it.

I didn't have any halloween parties to attend that year, and at my age I don't do much trick-or-treating, so by the time Halloween day rolled around, I still hadn't pulled together a costume. Was that going to stop an avid Instructables reader from coming through with a kick-ass Doc Ock costume? Heck no.

To be perfectly honest, while this was assembled at the last minute on Halloween night, it was not entirely a spontaneously creation. Like any good super-villian, I spent many weeks plotting and scheming.

This is my first Instructable, and probably not one that can be easily recreated to exact specifications. But if you are hell bent on making the scene as Doctor Octopus this Halloween, you should get some ideas here.

Step 1: Supplies

Picture of Supplies
All of the parts for this costume were gathered from my basement "workshop" (read: mess of tools and junk).

I had some lengths of pipe insulation on hand from an unfinished home improvement project. I also had a couple lengths of this soft copper tubing - it's the stuff you use to connect a refrigerator's ice maker to the water supply. My plan was to put the copper inside the pipe insulation to make them somewhat rigid and posable. Obviously, these would be the basis for Doctor Octopus' most distinguishing feature - his four robotic arms.

The backpack is smallish, form-fitting, and loaded with adjustment straps. I planned to somehow mount the robot arms. The other supplies were gathered as needed. In the end, they included:

- obligatory black duct tape (does this even need to be mentioned?)
- scrap piece of pine wood board
- deck screws
- "washers" (beer bottle caps)
- action accessories (neoprene back support belt, clunky sunglasses, pocket pouch thingy)
- some lengths of nylon cord
somethings telling ne to make this and be slenderman:D XD

very cool. 5/5 just one question, how do you get through doors?
*Sideways.* (Experience talking.) Completed this costume tonight for my son. CANNOT THANK THIS GUY ENOUGH FOR PROVIDING THIS INFORMATION!!! Photos to follow. :)
This is just the Instructable I've been looking for! I want to somehow combine your idea with the animatronic hands from this instructalble (http://www.instructables.com/id/Simple-Animatronics-robotic-hand/)
to give it a more real look! any ideas on how I can combine the 2? I want to be able to move the hands with string tied to my hands or legs somehow.
You should also add swimming goggles too, but even without it's still a pretty cool costume.
Who would want a store bought costume after seeing your very very cool handmade one?
I have a friend who grew up in really poor family, and her mom used to make all her clothes.  My friend really wanted "boughten" (cute expression huh?) Anyway, when she became an adult, and people paid her mom a lot of money to custom sew for them, she  realized that her mom was actually very talented.  Your children will look back on your inventions with real pride when they are older!

Wow, great! Just add some "claws" at the end of the "robotic-arms", as the original doc-oc has, and it would be perfect.

Not that I necessarily want to see it happen to you but i have always wanted to see a spontaneous fight between a guy in a spidey costume and a guy in a doc oc costume, or really any good hero/villain pair.

Sweet! In the dark, who can tell it's a 10-minute costume? Looks impressive.
