When you think of superhero teams with some seriously powerful members, most people will bring up the Justice League. After all, it's the team that has the likes of Batman, Green Lantern, Wonder Woman, the Flash, and Superman as some of its core members. On top of them, pretty much every major player in the DC Universe has been a member of the Justice League at one time or another.
While that includes some seriously heavy hitters, it also means the team has had plenty of members who barely compare to the team's top-tier characters. For every Superman, there's an unpowered do-gooder with a few tricks and skills barely better than the average non-meta human. That's not to say these characters aren't great on their own, but when you compare them to Wonder Woman, Superman, or the Flash - well, there's no comparison.
They may not be lame, bad, or terrible, but when you compare these characters to the Justice League's best, these folks are pretty much the worst and weakest characters to belong to the team. Find your favorite... or rather, least favorite character down below and vote up the character you consider to be the worst member of the Justice League.
Mystek may look like a dude, but that's actually a Korean woman named Seong who posed as a man for some unexplained reason. She began her career as a supervillain, but saw the error of her ways and joined the side of good.
Eventually, the Martian Manhunter offered her a position on his Justice League Task Force, but she only ever managed to make it a single mission. On the first outing of the JLTF, the team shot into space, but Mystek couldn't cope with the cramped quarters of the spaceship. She ended up shooting a hole in the hull of the ship, and was promptly sucked into the vacuum of space... where she died.
Blue Jay isn't exactly the most intimidating superhero to join the Justice League, but he does have the ability to shrink, and those wings are kind of cool. When he was recruited to Justice League Europe, he was wracked with self-doubt seeing as he didn't feel he was comparable to the powers of the other members of the team, and he was right.
He was soon elevated to the position of the team's commander, but it turned out this was a plot by Queen Bee to bring about the team's destruction. It couldn't have felt good to learn that all of his self-doubt was justified as a supervillain believed the best way to destroy a team was to make this guy its leader.
Everyone knows that DC and Marvel often copy one another's characters in one way or another, and it's hard not to see that Agent Liberty is little more than a thinly-veiled duplicate of Captain America. Despite this, he wasn't a horrible character, but he was hardly a good addition to the Justice League.
After all, he was just a guy with a jetpack, some weapons, and a suit, which endowed him with some heightened abilities. He joined up with the team to help in the fight against Brainiac, but he wasn't much help seeing as he was... well, a guy with a jetpack, some guns, and... you get the idea. He left the team and was eventually killed by Superwoman who dumped his corpse into Metropolis Bay.
Triumph was one of the founding members of the Justice League, which makes him one of the most important characters in DC Comics history. The only problem with that previous sentence is that the character wasn't introduced to fans until 1994, which makes his historical importance a tad suspect.
Triumph was introduced as one of those characters who had always been there, but everyone simply forgot about him. The way DC managed this was to explain that he was a founding member of the team, only he was teleported into an alternate dimension on his first mission, which effectively erased him from history. When he came back, he was little more than a forgettable jerk most people hated, and he was a terrible (re)addition to the team.
