Identification: Help? What's with the black leaves?

Can anyone Identify this plant?

The first photo shows a purple leaves, but it is actually the flash of my camera, that makes it;s seems to be purple, it is black in colour. The side of the leaves is also spiky.

The underside of the leaves is a darkshade of magenta/red.

The steam is yellow colour with red dots, there is spikes/thorns emerging from the red dots.

Thanks in advance, it's the first time I seen this plant, and I would like to know the name, so that I can take good care of it.

 

Difficult to be sure from your pics, possibly Begonia. See....
