Lord Drakkon’s Army
Lord Drakkon is an alternate version of Tommy Oliver that remained evil after the Sword Of Darkness was destroyed. He later leads an army to destroy the Power Rangers once and for all and succeed in interrupting Jason becoming the White Ranger. He fuses with the powers himself to become a Hybrid Ranger. After gaining these new powers, Lord Drakkon took over the entire planet and leads an army based off different Power Rangers called Ranger Sentries. After learning of another dimension where he turned good, he assists the Rita Repulsa of that dimension by sending her The Black Dragon. After Tommy & Billy travel to his dimension, he greets them and attempts to capture them. However, he is thwarted by Saba when he uses the White Tigerzord as a distraction in order to retreat. Lord Drakkon eventually finds the location of The Coinless base and succeeds in capturing Tommy. He offers to spare Tommy’s life in return for the Blue Power Morpher that The Coinless have in their possession. Trini then uses the Blue Power Coin to drain Lord Drakkon’s of his power. In his weakened state, Drakkon is challenged to a one-on-one fight by Tommy. He does not put up a good fight and jumps into a crevice to avoid capture. However, when the Mighty Morphin’ Power Rangers open up a portal back to their dimension, he is sent to their dimension with them and is captured by an army of soldiers.
The Black Dragon is a being Rita summoned by powering up the Black Crystal. After being summoned to their dimension, he destroys the Command Center, kidnaps Billy, disconnects the Power Rangers from the Morphin’ Grid & unleashes the Zords on a rampage throughout the Earth. After falling apart after the combined efforts of Tommy & Billy, it is revealed that The Black Dragon was just a zord Lord Drakkon was controlling from his dimension. The Black Dragon’s Armor is later used by Trini in order to fight off Rita’s force in the Command Center and to open up a portal to the alternate dimension to rescue Billy & Tommy.
