All about Havok (Wikipedia)

Havok (Alexander "Alex" Summers) is a fictional character, a mutant superhero in the Marvel Comics Universe and member of the X-Men. He first appears in Uncanny X-Men No.54 (March 1969), and was created by Arnold Drake, Don Heck and Neal Adams. Havok generates powerful “plasma blasts”, an ability he has had difficulty controlling. He is the son of Corsair, the younger brother of the X-Men's Cyclops, and the older brother of Vulcan. He often resents Cyclops' authoritative attitude and reputation as a model X-Man.

In contrast, Havok and his longtime love interest Polaris have had a love/hate relationship with the team, often finding themselves roped into it. Both were also members of the 1990s-era Pentagon-sponsored mutant team X-Factor. After X-Factor disbanded, Havok starred in Mutant X, a series in which he explored a strange alternate reality. He has since returned to the X-Men, later taking over his father's role as leader of theStarjammers to bring Vulcan's reign over the Shi'ar to an end.

Lucas Till played Havok, as a member of the X-Men, in 2011's superhero film X-Men: First Class. Till will return as Havok in the upcoming 2014 film, X-Men: Days of Future Past.

• Actor Lucas Till played Havok in X-Men: First Class.^[44] According to executive producer Bryan Singer, Havok was not portrayed as Cyclops' brother in the film, but "somehow [was] related to him in a way that works for the film."^[45] Initially having trouble controlling the energy bursts he releases as part of his powers, Alex eventually manages to focus his abilities thanks to equipment developed by Professor X and Hank McCoy.

• Lucas Till will reprise his role in X-Men: Days of Future Past.^[46]  

Here is a Havok trailer for X-men First Class. I do not own this!

All about Banshee (Wikipedia)

Banshee is a fictional character, a superhero who appears in comic books published by Marvel Comics. He operates as a member of the X-Men. Created by writer Roy Thomas and artist Werner Roth, the character first appeared in X-Men #28 (January 1967).

An Irish mutant, Banshee possesses a "sonic scream," capable of harming enemies’ auditory systems and causing physical vibrations. He is named after the banshee, a legendary ghost from Irish mythology, said to possess a powerful cry, although the banshee spirit is invariably female and the Irish Gaelic to English translation of Bean Sidhe (Banshee) is literally Fairy Woman, making it an odd choice for a male character (the male version is Fear Sidhe).

A former Interpol agent and NYPD officer, Banshee was always a decade older than most of the X-Men and had only a relatively short tenure as a full-time X-Man. He was, however, a mentor of the 1990s-era junior team Generation X. Caleb Landry Jones played the role of Banshee in 2011's X-Men: First Class.

• Actor Caleb Landry Jones played Banshee in X-Men: First Class. He fought Angel Salvadore during the climatic battle at the end of the film. In this version of the story, a prequel to the X-Men trilogy, he became one of the founding members of X-Men.^[33] Irish actor Robert Sheehan was originally cast as the character but dropped out due to his show Misfits.^[34]
• Jones won't be back as Banshee in the sequel, X-Men: Days of Future Past.^[35]

Here are 2 clips from X-men First Class that show Banshee. I do not own this!!!

All about Bolivar Trask (Wikipedia)

Bolivar Trask is a fictional character appearing in publications by Marvel Comics. He is a military scientist who is well known as the creator of the Sentinels. His appearance is modeled on that of Walt Disney. He is also the father of Larry Trask. Bolivar Trask was an anthropologist who saw the rise of mutants as a threat to humanity. Bolivar decides that humanity has to fight back against the mutants and develops robotic guardians for humanity, known as the Sentinels. His son Larry was protected from the Sentinels' ability to detect mutants due to the medallion Bolivar had given him. To stop the Sentinels, Xavier summons his X-Men. The X-Men fight the Sentinels, but Beast is captured. To reveal the X-Men's secrets, the Sentinels tell Trask to use a device to read Beast's mind. Trask discovers that the X-Men were mutants protecting humanity and realizes that he had been wrong. He helps the X-Men defeat the Sentinels by sacrificing himself to destroy the Sentinel's base.^[3]

• Bill Duke portrays a man named Trask in X-Men: The Last Stand. Here, he is the head of the Department of Homeland Security. While a holographic Sentinel does appear in the film as part of a Danger Room session, Trask has no (presumed) connection to the Sentinels.

Peter Dinklage will portray Bolivar Trask as the main antagonist in the upcoming X-Men: Days of Future Past.^[13]
