Alan Hallman was selected by the Parliament of Trees to be the planet's earth elemental before Alec Holland became the Swamp Thing. He had been a scientist working on a formula to repair damaged crops when the Parliament chose him, and he died in flames - as all elementals must.
However, while traversing The Green, he was captured within a creature of The Grey, which broke him down and converted him into fungus and mould. He was recreated as an emissary of The Grey by Matango, who gathered Hallman's consciousness back together in his Chamber of Dreams.
With Matango's return from Hell, Alan Hallman was released into The Green to find and capture the Swamp Thing and his daughter Tefé, and force them to surrender their individuality to The Grey.
