simple, i then use my genius to create a solid tesseract by using the theory 2,4,6,8 (look it up if you must)
This illogical, unesxistent shape(to our dimesion) causes a rift in time and space (you HAVE to travel in time to get to the fourth dimension, so ill make myself an exception). I go into the rift in a protective bubble and into the fourth dimension. I see many strange 4d shapes that causes chaos in my brain, but i ignore them and use my mind power to find the only 3d shape in this wierd world(apart from myself) i quickly find that cap and leave the dimension. closing the gate forever behind me.
where i hide will come soon
