Justice League or Avengers?

The Justice League and Avengers question is almost the same as asking "DC or Marvel?". The right answer is Justice League. The Avengers are diverse, but in a very limited way (however that works out). The only extension of the Avengers is the New Avengers, whereas the Justice League has brances of the Teen Titans, and Justice League Unlimited.

The main roster of the Avengers consist of: Captain America, Spider-Man, Thor, Hulk, Iron Man, Ant-Man, and Wonder-Man. Most of the time, the Avengers do about the same thing as the Justice League. They fight off the bad guys and do the good thing. Some of them, however, are slightly rogue characters. Wolverine acts roughly, though he knows to do the right thing. Hulk is a very strange character. Sometimes, he is a hero. Other times, he is fighting one or more of the Avengers. Thor is just a strange hero. A Norse god, he seems much like Captain Marvel. Actually, he seems a bit too similar to chalk up the similarities to chance. The New Avengers are pretty much the children of the original Avengers; a "new-generation" type of group to appeal to younger audiences.

The Justice League is my favorite band of superheroes. Ever. The main League members (from the animated series) are Batman, Superman, Wonder Woman, Hawkgirl, the Flash, Martian Manhunter, and the Green Lantern (John Stewart). The Justice League Unlimited is an expanded version of the Justice League, tying nearly all of the DC Universe heroes together. The Justice League Unlimited brings together heroes from all over the galaxy, and even some from other dimensions. Some of the bigger names in Justice League Unlimited include the Red Tornado, Green Arrow, Black Canary, the Question, and Supergirl. Many of these heroes are acquaintances, and get along with each other very well. There are also some relationships within the League. John Stewart has been romantically linked to both Hawkgirl (Shayera) and Vixen, and Batman has been seen with Wonder Woman. Black Canary and Green Arrow are actually married.

The Avengers would never win against the Justice League. Though both teams appear to get along well, the Justice League works so smoothly and flawlessly because of Batman's plans that the Avengers cannot match up to them in teamwork. Both teams have the one guy who, while harsh and mean, always does the right thing (Batman of the Justice League, Wolverine of the Avengers). Both teams also have the flashy cover-boy that symbolizes America (Superman of the Justice League, Captain America of the Avengers). Also, both teams have the witty, comic relief character (Flash and Spider-Man). The one thing that makes the Avengers so much better is that they span over multiple planets, races and galaxies. The Avengers have no martians, only a Norse God.

The Green Arrow, or Oliver "Ollie" Queen, is a superhero who used to be an executive of his company. He sold his company for a large sum of money in order to be Green Arrow full-time, eventually training Speedy as his protegé just as Batman trained Robin. Green Arrow dresses as Robin Hood and is an expert with the bow and arrow. The Green Arrow is typically shown as a rebel, and a highly skeptical man. He has appeared in comics and television shows.
Ollie Queen sold his company for three billion dollars in order to become a full-time hero. He is a member of the Justice League, but was skeptical of the group at first. Green Arrow does not use only conventional arrows; he invents his own arrows with various functions. Among the stranger arrows he uses is the 'boxing glove arrow'. Some others include a glue arrow, net arrow, bomb arrow, and grappling arrow. He is often seen working with the Green Lantern. The most famous Green Arrow story was one in which Speedy, his red-clad sidekick, was addicted to heroin. The story was in Green Lantern #2. Green Lantern and Green Arrow fight off drug addicts and bust a drug ring.
Green Arrow has appeared in the television series Smallville as a younger man who has not yet sold his company to become a full-time hero. He has a more modern costume both in style and in technology. He becomes a trusted friend of Clark Kent's, and appears in the Justice League of Smallville. Green Arrow also has a regular appearance in the show Justice League Unlimited. His appearance follows the classic comic appearance, with the beard and the clothing. He is shown with his significant other, Black Canary. In this show, Green Arrow often acts as a voice for the public and a brave, loyal friend to all in the Justice League. Green Arrow also has an appearance in The Batman. A movie for Green Arrow/ Ollie Queen has been talked about, and a script has been written. Filming, however, has not started yet.
The Green Arrow is a character who provides comic relief when it is needed, especially in Justice League Unlimited. He does, however have slight mood swings. He is randomly rude to other heroes of the Justice League, but only apologizes after they have turned their back.
The Green Arrow is a very rebellious character. The "cool guy" of the DC Universe, he can be compared to Tony Stark of the Marvel Universe. Queen often uses crude humor, and he doesn't quite seem to care about everyone else's feelings. Queen's character is a stark contrast to Superman, who tries to please everyone. Queen appears very selfish at first, but he has a good heart and he knows he must do the right thing in the end. All in all, a pretty cool guy.

The Joker

The Joker is probably my favorite villain of all. He is Batman's most noted enemy, and he also causes trouble for the Justice League. He has no real history; his origin story is varied according to the writer. The most common origin story is that the Joker was essentially created by Batman. His name in this origin story is usually Jack Napier. Napier was a mobster, doing jobs for a large triad. Eventually, he broke away and tried to form his own gang. Napier and his gang planned to rob the Ace Chemical Plant. Their robbery was stopped by Batman. Either an accident or an attempt to escape led to Napier's fall right into a vat of chemicals. The chemicals were then flushed out into the body of water somewhere around the plant. The chemical bath bleached the Joker's skin, turned his lips red and dyed his hair green; he also became insane. Napier gave himself the name The Joker, and swore to prove his criminal genius.
The Joker has had many, many incarnations between comics, cartoons and the big screen. The most recent incarnation, played by the late Heath Ledger, shows a Joker who is a criminal genius with make-up. The make-up is applied unevenly, but his face is white, the areas around his eyes are black, he has stringy hair with green highlights and a frightening "smile". The smile is red makeup applied from one scar to another; his scars make him seem to be "smiling" all the time. This Joker is from The Dark Knight, Christopher Nolan's summer blockbuster and sequel to Batman Begins. In The Dark Knight, the Joker has no real origin story. The only glimpse of an origin is his stories about his scars; however, the stories are conflicting and may both be lies. The two other big screen adaptations of the Joker are played by Jack Nicholson in Batman (1989) and Cesar Romero in Batman (1966). Jack Nicholson's Joker is more faithful to the comics, including his fall into a chemical vat and his crude jokes. Cesar Romero's Joker is not heard of much today; the movie and ensuing television series have been criticized for the excessive camp humor.
The Joker has been in a few television series. The first is the series Batman, which followed the 1966 movie. The Joker was played by Cesar Romero. The next few cartoons are seldom heard of, and follow the campy style of Batman (1966). The most popular television incarnation of the Joker is of Batman: The Animated Series. This Joker is somewhat similar to the Joker picture displayed with the article. The Joker was voiced by Mark Hamill, the actor who brought Luke Skywalker to the silver screen in the Star Wars movies. Hamill's Joker appears in the movie Batman: Mask of the Phantasm, a movie from Batman: The Animated Series, and Batman Beyond: Return of the Joker, a direct-to-video movie from the Batman: TAS spinoff Batman Beyond. He also appears in a few episodes of the television shows Batman Beyond, Justice League and Static Shock. Hamill's Joker voice seems to have been permanently linked to the Joker's cartoon adaptations; it is used as a comparison for all of the recent portrayals. The Joker also appears in The Batman, a series from KidsWB!, and is voiced by Kevin Michael Richardson. This Joker has been harshly criticized for the drastic difference in appearance; he has long hair (possibly dreadlocks), wears very different clothes, usually walks around barefoot, and has sharply honed combat skills. He seems to use his feet just as well as his hands, giving the impression that he is a monkey. The most recent cartoon adaptation of the Joker is in Batman: The Brave and the Bold. This show has been praised by many for its seeming mix of Batman: The Animated Series and some of the campier elements of Batman. The Brave and Bold Joker is voiced by Jeff Bennett, and has only appeared in two episodes.
In Batman: Mask of the Phantasm as well as Batman Beyond: Return of the Joker, the Joker dies. In Mask of the Phantasm, however, his death is not shown, so there is a possibility he lived. In Return of the Joker, he is visibly killed and, in the animated universe created by producer Bruce Timm, finally given closure. Bruce Timm's animated universe follows a timeline, in which Mask of the Phantasm and Return of the Joker are included. Return of the Joker may be the final event. In the 1989 film Batman, the Joker is seen to be killed by dropping from an extraordinary height. His final joke is a sound recording of his laughter, which goes off when he lands and dies. In The Dark Knight, the Joker is not killed off.
The Joker is, for some reason, the classic villain of Batman. He is always going to be associated with Batman, especially after the movie The Dark Knight. The Joker of the Batman animated series and Justice League cartoons is much more lively than the silver screen adaptations. He always has a name for Batman (Guano-Man and Batsy are among the most common), and he always has a trick up his sleeve. The Joker of the 1989 Batman film is a faithful adaptation who usually has a trick up his sleeve, but does not taunt Batman as much. The Joker of The Dark Knight is a very dirty, grimy, intinimidating man. He taunts Batman not with names but with psychological tricks. He wants to prove that even the best of people can be broken, and does so by breaking Harvey Dent. He also tries to "break" Batman in the interrogation room, succeeding in infuriating Batman. This seems to be all he wants, and proceeds to mess with Batman some more in regards to the two hostages he has taken. The Joker is a very abnormal guy who has no sane explanation for his actions. His motives are widely unknown, and he is the only one who knows what he does and why.
