Man of Metal III: Battle Across Time.

Viking help and hard battles.

As Rick tries to figure out what creatures they are talking about, they explain that the key thing to killing the creatures is with the help of a amulet which can vanquish almost anything that isn't human, Rick goes on a quest to find the amulet and he makes his way through the woods until he battles 6 were-wolf like creatures who injure him badly until he manages to make it to a old cabin but not long before a duplicate version of himself battles him.
Rick tries his best to battle his duplicate but he is overpowered so he uses his lightning strike to kill him, Rick decides to heal himself quickly and he goes to find the amulet. Fortunately the radar glasses that he found in the lair of Zod couple moments back gives Rick the trail to the amulet and he finds it but not long before a couple of hungry looking demons try to grab it off him.
He defeats them and tries to head back to the castle but is unaware that the evil army followed him and they begin to attack, a great battle took place over the possession of the amulet and from that moment, his premonition occurs and it shows that a time portal opens just before he gets killed so he defeats the whole army with the help of the Vikings and then the time portal opens and takes him to 1990 where again he finds out he is trapped in the wrong time.
