In the upcoming "Avengers" movie, fans have already been treated to some sneak peaks in the previous movie franchises like "Captain America 2: The Winter Solder,""Ironman 3" and the first "Avengers" movie itself. So, "Avengers" fans may already have a hint what the new movie will be. But of course, Joss Whedon still has some surprises up his sleeves to make the movie experience a lot more exciting.

Ultron

"Avengers: Age of Ultron" offers tons of new things from weapons, costumes, to new villains and Avengers. Let's start off with Ultron. According to JoBlo, Ultron will have three versions—from basic to an ungraded one. In the film, Ultron will be coated with Vibranium metal, but will not resemble a robot too much.

There are two rumors as to where Ultron originally came from. However, both rumors stem from Tony Stark since Ultron was made from Iron Man's armor. The first is that Tony Stark adopted Ultron and may have something to do with Jarvis (AI Assistant) leaving Stark. The second is that Tony Stark actually created Ultron himself.

The Twins

Twins Scarlet Witch and Quicksilver will join the movie in "Avengers 2: Age of Ultron." What's unsure is where their allegiance will lie. It is said that the twins will work under HYDRA first and will not get along with the Avengers since they are children of Magneto.

The Iron Legion and Stark Tower

Seen at the end of "Iron Man 3," more of the Iron Legion will be seen in the new Avengers movie. Due to the destruction of S.H.I.E.L.D., Tony Stark created more Iron Man drones to help protect the people and maintain peace and quiet as the Avengers are now in the public eye. Also, the Avengers no longer have a home and is now staying in Stark Towers.

Costumes, Weapons, Tech

While staying under the roof of Tony Stark, the Avengers were given new costumes and tech by Stark himself. The Avengers will use a new logo. Hawkeye's costume improves. The Hulk's costume will now grow and shrink and Black Widow will have two fighting sticks that can stun.

Possible Cameos

Vision will be seen towards the end of the movie. His costume will be very similar to his costume in the comics. War Machine and Falcon might also make an appearance.

"Avengers 2: Age of Ultron" will hit the theaters May 1, 2015.
