Ep 21. Brother, Can You Spare an Arrowhead?

King Mondo gains full possession of the arrowhead and continues to keep Tommy's brother David, trapped in the cave which holds the spirits of ancient evil creatures. Tommy and the Rangers continue to battle Mace Face with the Red Battlezord, finally forming the ZEO Megabattlezord to defeat the monster. In the Viewing Globe, the Rangers can see David being threatened by Autochton, an ancient monster spirit. When Tommy suddenly discovers that whoever has the arrowhead controls the spirits, he is able to rescue David before it is too late. King Mondo then forces the Autochthon to battle the Rangers as a last effort to destroy them, but luckily, Tommy retains the arrowhead and control of the ancient spirits. To retaliate, King Mondo makes Autochton grow larger, and the Rangers defeat it once again with the ZEO Megabattlezord. Tommy and David are finally reunited, agreeing that they better keep both halves of the arrowhead separated from now on.
