Aroon and Sakda Srisai were identical twins and just started manifesting their superstrength uber powers when they were abducted by Dr. Mengele and 'adopted' in to die Kinder. This presented an unique opportunity for the evil doctor. He had conducted experiments on Jewish twins in the Nazi death camps many years before. And here was the second pair of uber twins that he had found in his lifetime.

Fortunately, these two uber twins survived the experimentation which resulted ultimately of fusing them together back-to-back. Mengele smiled with the irony of his final twins experiment that created a superpowerful Siamese twins.

Because of the success of the experiment, the twins held a special place in the evil doctor's heart. He treated them as a favorite among his 'children'. And he gave them the special position as his personal bodyguard and strongman.

Leibwächter behaves like the favorite child of Dr. Mengele. They often crave his attention and approval and will attempt to do nothing that will bring about his disdain. In many ways, they are the perfect bodyguard and servant for their 'father'.

"You'll have to get around my brother and me."

Aroon and Sakda Srisai would have been superstrong bricks even without the manipulations of Dr. Mengele. They were further enhanced by his Unpain therapy - a very painful process in itself. And finally, they were physically linked together. The result is a two-headed, four-armed, four-legged very tough strongman.

Leibwächter is a large conjoined twin with black hair and well-tanned skin. They wear typical die Kinder uniforms - red with the Kinder insignia - specially tailored, of course.
