Lion El'Johnson

A similar premise as my Rogal Dorn ff.

The MC dies and gets his wish granted to be 'like' his favourite character, Lion El'Johnson. What he didn't specify, is that he doesn't want to be born in the Warhammer 40k Universe. Now he finds himself in the chaotic universe, having to fight his way through hardship and chaos.

Thankfully, the ROB who reincarnated him gave him something on the way in the form of a Meta Essence. This should allow him to become the strongest of all Primarchs, no question. He will also first visit a different world before he is inevitably thrown into the Warhammer 40k Universe.
