Forsung vs Thanos
Forsung is the Eldest of the 3 enchanters,and actually had the guts to challenge Odin himself in personal battle.Their battle went from one side of the universe to the other.Destroying planets and re-egnighting dead stars.Odin did eventually win,but it was no easy fight.I know times have changed.But could Thanos find away to beat Forsung,I get the feeling he would find away.
