The Snowy Star Owl Lineage Factor was the most straight forward. It too caused a change down to the cellular level, but it was in Leonel's blood.
Usually, blood was formed of plasma, red blood cells, white blood cells and finally platelets. Leonel's blood, though, had all sorts of extra oddities in it, one of which had the signature of his Snowy Star Owl Lineage Factor. Since Leonel didn't know what one would call it, he just called them owl cells.
This nameless cell was what Leonel believed gave him the innate affinity toward Snow Force and there were about 50 trillion of them in Leonel's blood. And, each one of these owl cells had a special organelle within them that Leonel felt was very reminiscent of mitochondria.
