|Real name||Henry McCoy|
|First appearance||Castaways #67|
Beast was loyal to Magneto, and when he left to form the Brotherhood, he had Beast stay and act as a spy. He did as he was told and leaked information, which got his teammates, Angel and Magik, killed by Magneto.
His first mission was on a world where Captain America had never been thawed out. The Avengers eventually disbanded and heroes were forced to register with S.H.I.E.L.D or die. Their mission was to bring down S.H.I.E.L.D., so Beast took advantage of it and killed Maria Hill, mercilessly and happily.
