Complete Monster: Black Cross Fuhrer, later known as Black Cross King, serves as the leader of the Black Cross Army. An alien from the Cassiopeia constellation, he created his army of minions and androids with the express purpose of conquering the world. When threatened by a team of United Nations officers, he would order his men to slaughter all of them in the Japanese branch, leaving only one survivor from each base. He would launch various attacks on the city and was even willing to kill children if it meant advancing his goal. If any of his minions so much as thought of disobeying him, he would kill them on the spot. Nearing defeat, he would use the sacrifice of his most loyal general, Golden Mask, as a way to both escape and carpet-bomb Tokyo, causing untold destruction, not even caring about the death of Golden Mask. Caring only about himself and power, he would also serve as a prototype of countless, diabolical villains of the franchise that would succeed him.
Hilarious in Hindsight: In episode 7, the villain Crescent Moon Mask jokes about turning Momorenger into an "Ookamirenger" (the villain was turning people into werewolves, which is what Ookami means). 42 years later, there is an ACTUAL Ookami Ranger as opposed to Rangers just themed on wolves) and he's certainly NOT a villain that would've helped Crescent Moon Mask (Garu's an alien that's always a humanoid wolf, but his species is called "Wolfmen")
To be more precise, fans of newer seasons (or Power Rangers fans wanting to get in) will be welcomed by a Sentai that features very little of the common characteristics, like giant robots or combinable weapons. The suit designs are also fairly nonstandard by today's designs, and the special effects didn't allow for a lot of the flashy attacks used on both sides these days. Everything like that that merely doesn't look as good as in the 80s Sentai that are recently getting subbed flat-out couldn't be done back then, before the series proved itself worthy of the budget for even the best 1975 had to offer. While originally ground breaking and impressive, time has not helped this series at all.
