"Tremble Before -- Dreadhelm!"The Sentinels encounter perhaps their greatest foe, the (would be) world conquering Dreadhelm!
Newest members Fighting Yank, Marksman, Wildfire, and The Flame fight alongside Nelvana to stop this Alexander the Great wannabe from taking over (for our own good).
He would return time and time again to plague them, and even superheroes of other universes!

The Fraims further define the Sentinels and Standard Comics Universe with (I hope) this nifty villain. My try at a Dr. Doom level villain.
