I hate to be the bearer of bad news. But um Prometheus shouldn't be mentioned anymore since the version that beat Shiva isn't the original one. The original one was put into a coma by J'Jonn at the behest of Batman. The one who was Hush's little follower and beat Shiva was going to be his Robin and instead donned the suit when the original disappeared.
Yeah um... this was all in the one shot that came out earlier this year in January. Still if this gets us into posting a ton of Cass moments and fights I'M THERE! I just might upload Slade vs Cass round 1 from Nightwing or Cass vs Ravager.
