Origin

Crossbones was born as Nicholas, a bright young boy. He grew up in a parallel reality on a distant paradise-like planet. His father was a space-cop whom fought an intergalactic war. Nicholas looked up to his father a great deal and his father's friends; that reality's Captain America and Nick Fury. Although the war raged on in the galaxy, Nicholas had peaceful childhood and was best friends with Mr. Lobkins, and android home-keeper. It was however then that the war came to Nicholas' home-planet. In a surprise attack, the whole small world was devastated, with most of it's residents dead and Nicholas gravely wounded to one of his eyes. The enormous failure of the space-heroes to stop this attack caused Nicholas to alter his views as he became embittered and looking for revenge as he grew older.
