That said, the first 10 villains the Justice League fought in comics were not on the same level, and some were a little less powerful than others.
10) Xotar the Weapons Master

The Weapons Master was the second-ever villain the Justice League fought in comics, and he was a huge letdown from Starro the Conqueror. This happened in The Brave and the Bold #29 when a being from the future (11,960 A.D.) known as Xotar knows he is fated to travel to the past and fight the team, so he tries to find futuristic weapons that can beat them so he can change the future. However, every member destroyed his weapons, with Superman eliminating his last weapon and sending him back to the future in defeat. The Weapons Master didn’t live up to his name and was nothing compared to the JLA.
9) Kanjar Ro

Kanjar Ro was a villain the Justice League faced in Justice League of America #3. However, this was a unique situation because he wanted the JLA to help him, but went about it the wrong way. Kanjar Ro was an alien who abducted the Justice League and then immobilized Earth, demanding that the JLA help him fight off his enemies (Jyathis, Kromm, and Sayyar). When they succeeded, he refused to release them unless they promised not to attack him, and they were able to get free anyway and banished Kanjar Ro and his enemies to a meteor planet. The fact that he wasn’t willing to fight on his own and was cowardly when the end came showed his lack of power compared to other JLA villains.
8) Amos Fortune

Amos Fortune was a villain who fought the Justice League in Justice League of America #6. This issue began with each member of the JLA suffering from bad luck, and Dr. Amos Fortune is a man who has spent his life studying luck and how to manipulate it for his own success. This caused him to create a device that causes bad luck through a “luck gland” in the body. However, there was one thing that he didn’t take into account. Martian Manhunter’s Martian physiology made him immune to it, and he defeated AMos Fortune easily. He was able to take down the other JLA members, making him a little more dangerous than other villains. He also returned eight issues later with a team he had formed, but lost once again.
7) Simon Magus

In Justice League of America #2, the team battled invaders from Magic-Land, and they were led by the villain known as Simon Magus. This all started when all man-made machines on Earth stopped working, and the JLA learned that magic had overtaken technology as the dominant force. Simon Magus was one of the evil magicians behind this, along with Saturna and the Troll King. The JLA needed the help of the great magician Merlin to stop these evil magic users, making Magus a powerful threat early in the Justice League’s career.
6) Appellaxian Invaders

The first villains that the Justice League fought when they officially formed for the first time weren’t the first villains they fought in DC continuity. Instead, this was a story retold in Justice League of America #9, and it had Appellaxian warriors sent to Earth to see who could conquer the planet first, and the winner would be the new ruler. They attacked different parts of the planet and faced the different members of the JLA, falling in defeat. After this victory, which wasn’t as hard as expected, the members agreed to form the Justice League.
