Origin

Shiro Yoshida grew up with a huge resentment against the United States. His mother was exposed to the radiation of the atomic bomb at Hiroshima and she died during his birth. His dad, a member of the Japanese Clan Yashida, became a diplomat to the United Nations and Shiro was pretty much raised by his uncle. His uncle Tomo was purely anti-America. He instilled his hatred upon Shiro and is responsible for giving him his costume and codename of Sunfire.

It was Tomo's plan to use Shiro as a weapon against the U.S. Tomo had Shiro attack the Capital building in Washington but was stopped by the mutant team, the X-Men. Tomo then shot Shiro's father when he tried to reason with him.

Shiro later had encounters with Namor, the Sub-Mariner and then Iron Man. It was these encounters that started Shiro thinking his hatred against America wasn't entirely warranted.

When the X-Men were being held captive by the living island Krakoa, Charles Xavier (Professor X) offered Shiro a place in the team. Shiro assisted in the rescue but refused to remain with the X-Men saying his place was in Japan.

Over the years, Shiro and the X-Men worked together and he eventually took a position with the X-Corporation in its branch in India to help and rescue mutants in need.

Recently, Shiro was wounded and lost his legs in a battle with Lady Deathstrike. He then allowed Rogue to absorb his mutant powers in order to defeat Deathstrike. Broken, wounded, and powerless Shiro was taken by Apocalypse and turned into the Horsemen of Apocalypse Famine. He emerged from Apocalypse's temple in a costume similar to the costume he wore in the Age of Apocalypse to fight the X-Men. His legs had been returned to him, as well as a modified version of his previous flame powers. As famine, he could modulate the intensity of his flame in a way that would cause immense feelings of starvation in anyone around him. When Apocalypse's latest plan against humanity was thwarted, he and Gambit (who recently was turned into the Horseman Death) left together.

Both of them seems to have joined the new Marauders.
