"The Onslaught from Rigel" by Fletcher Pratt is a science fiction novella first published in 1932. When a mysterious comet approaches Earth, Ben Ruby awakens to find himself transformed into a metal being while most of humanity has become lifeless statues. The comet is actually a spacecraft carrying the Lassans—militaristic elephantoid aliens from Rigel who plan to enslave or destroy all survivors. Ruby and fellow survivors must face thought-controlled creatures and armored forces as they fight to reclaim their planet and their humanity. (This is an automatically generated summary.)
