I'm very excited, as my local library now has Mighty Morphin Power Rangers volumes 4-12! I started reading them last night, getting through volumes 4 and 5.
Volume 4 picks up where 3 left off - Billy and Tommy are in Lord Drakkon's world, having gone with Sabba to the Coinless. The Coinless, however, aren't taking any chances with these two in case they are Drakkon's spies. But their leader, Zach, recognizes Sabba, who, when they last saw each other, had told Zach that he would return with the ones who would save their world. Unfortunately, Drakkon tracked the sabre to the Coinless's base and mounts a full assault!
Meanwhile the other Rangers are trying to figure out a way to get the Command Centre back from Rita. Finster finds Alpha 5's head, and reprograms it to lead the Rangers into a trap! At Rita's behest, he's sculpted an army of Goldars, who are much more savage than the original.
Against overwhelming odds, the Rangers succeed, and even manage to find Billy's power coin! Trini uses it and the Black Dragon armor to open a portal to the other dimension to Billy and Tommy, just in time to help against Lord Drakkon's forces! The Rangers save the day, freeing both worlds from tyranny.
The story continues to be excellent, and I can't wait to see how the Rangers deal with Finster's invisible monster army in the next volume!
