A former terrorist trainer has become a comic book author as he moved from helping the terrorists to opposing the terrorists.

JAKARTA, Indonesia (AP) -- The real life adventures of former al-Qaida-linked militant Nasir Abas have become a comic book in Indonesia, chronicling his transformation from foe to invaluable ally in the fight against terrorism.

The story of the soft-spoken, seemingly mild-mannered 42-year-old - recognized by strangers on the streets and even asked for the occasional autograph - is well-known in the world's most populous Muslim country.

He went from helping train Muslim extremists who carried out some of Southeast Asia's deadliest attacks, including the 2002 Bali bombings, to informing police about the inner-workings of the Jemaah Islamiyah network.

He's also joined a government program to convince convicted terrorists that killing unarmed civilians in the name of their faith is wrong.
