Hero of Cult Michael Ironside has joined The Flash. Ironside will be guest starring in an episode as Lewis Snart, the abusive father of Leonard (Wentworth Miller) and Lisa (Peyton List).  Ironside’s character does not have that much of a back story in the comics apart from the fact he was that abusive Leonard went to live with his Grandfather due to the abusive.

Just what impact this will have on Captain Cold and The Golden Glider remains to be seen.

The Flash returns to the CW on October 7th.
