HYDRA Preparatory Academy

HYDRA Preparatory Academy, was a high school where members of HYDRA sent their children to be taught the ways of the organisation. General Hale went to school there, along with Wolfgang von Strucker, Jasper Sitwell and Hale's daughter Ruby in more recent years. Daniel Whitehall taught at the academy, possibly until or during his appearance in Season 2 of Agents of S.H.I.E.L.D.

The HYDRA Academy made its students go through "Rites of passage" Which included the killing of the student's dog. This tradition had been seen previously with John Garrett and Grant Ward
