Ingo Pech was the First Captain of the Alpha Legion during the Great Crusade and Horus Heresy eras. Like many Astartes within his Legion, he was surgically modified to resemble his Primarchs Alpharius and Omegon.
When the Cabal Perpetual named John Grammaticus sought to enlist the Alpha Legion into the service of the Cabal's agenda to destroy Chaos, he met with Pech as well as Thias Herzog, and the true Primarchs, all in the guise of Alpharius.
