First up the human cast Mark Wahlberg as Cade Yeager, an inventor who is now the autobots new companion
Frank Grillo as Cade's older brother and Tessa's uncle who is a former NEST operative in charge of keeping the handful of autobots that Harold Attinger mentioned safe from being hunted down. Surely Grillo will be busy reprising his role as Crossbones in Captain America 3 but slight chances of him joining up with Wahlberg against the decepticons and Quintessons are still possible as long as he does not become preoccupied by other film projects that are set for 2016.
Jack Reynor and Nicola Peltz as Shane Dyson and Tessa Yeager, the new young couple of the sequel trilogy. Shane is a race car driver who had a struggle with Cade when they first met but now after surviving the battle and uprising in Hong Kong, Cade now approves his relationship with his daughter. As for Tessa, Cade's daughter, who enjoys her years of being young and having fun but also concerned with what her father does as an inventor, she will be expected to be at college in the 5th film while it is unclear if her boyfriend will be there with her attending classes or not.
Now before going over more possible newcoming and returning human cast members, it wouldn't hurt to have at least a few of the original cast members from the first trilogy to help make the plot of this next film more interesting
Rosie Huntington Whitley and Shia Labeouf as Carly and Sam Witwicky, the couple from the first Transformers cinematic trilogy should return to meet Cade, Tessa, and Shane to share their experiences that they had hanging out with the autobots, for what they had in common throughout the films and perhaps team up with them against the decepticons and the Quintessons for this next film. They are also expected to have a son named Daniel Witwicky too. Also once Sam gets involved in the war again, Cade will be there to man him up.
Josh Duhamel and Tyrese Gibson as William Lennox and Robert Epps, two of the soldiers who survived Blackout's attack in Qatar in the first film who became founding members of N.E.S.T., a strike team of human forces that assisted the autobots in movies 2 and 3 until Sentinel Prime's betrayal and the invasion of chicago caused government officials to abolish their alliance with the autobots. If Duhamel and Gibson are able to return for the next film, the are sure to be among many military operatives helping safeguard many other autobots who the CIA terrorists known as Cemetery Wind were unable to hunt down.
Kevin Dunn as Ron Witwicky, Sam's father who is expected to return and meet up with Cade and discuss their relationships with their kids
Now back to some of the returning cast members from Age of Extinction and some newcomers
Stanley Tucci as Joshua Joyce, CEO of KSI who now becomes one of the good guys in the sequel trilogy. After all the destruction that went down in Age of Extinction, Joyce is sure to be paying a fortune getting all the mess fixed up from Galvatron and Lockdown's attacks and if he still has $10 billion dollars or more, his company may still be in business, and if so, he might be able to provide the autobots with some new additional Robot help which involves new autobots built by his company.
Li Bingbing as Su Yueming, CEO of the KSI factory in China and a love interest of Joshua Joyce which hints here possible return for the 5th and 6th films
Eva Longoria, Kate Beckensale, Paula Patton, or Stephanie Szostak as Cade's new girlfriend. Surely since Cade was okay with his daughter dating Shane after making it through the rough situations in AOE, he's very much gonna need to find himself a girlfriend, after all he can't just spend all of his time in the movie inventing and helping autobots
Gigi Hadid as Tessa's college roommate
Sophia Myles as Darcy, Joshua Joyce's assistant
James Bachman as Gill Wembley, one of Joshua Joyce's scientists who has an eating disorder and acts silly and dumb sometimes
and Gary Oldman as a new government official who is willing to have both human military and autobot alliances put back together after Harold Attinger's operations were exposed
next up, the Autobots
Peter Cullen as Optimus Prime, leader of the autobots who has gone into space in search of the Quintessons who were reffered to as the Creators in Age of Extinction. Surely Optimus will be back to meet up with his autobots but what ever his creators have in store for him will be revealed soon.
Bumblebee, the unforgetable autobot who stll can't talk and is funny when iit comes to being sensitive
John Goodman as Hound, the autobot that has been waited for return to the media since the original series. And with Hound being depicted as a big fat green Transformer that makes him look like Bulkhead and as a new weapons specialist replacing Ironhide, he is very much likely to last throughout the next two films
John DiMaggio as Crosshairs, an autobot who is into fighting and is the second character voiced by DiMaggio in the cinematic films.
Ken Watanabe as Drift, the samurai autobot who uses swords and follows Japanese customs
Now for some newcoming autobots in the film, let's start with the ones that have been given sanctuary since their alliance with the military had been abolished
Liam Neeson as Ultra Magnus, high ranking commander of the autobots who has taken charge of looking out for the autobots with him in the sanctuary
Kelly Hu as Override, a female autobot who joins up with the group of Autobots from Transformers Age of Extinction thus helping Bumblebee keep Tessa safe out of harm's way
George Cloony as Trailbreaker an autobot bunkered with Ultra Magnus in the sanctuary
Colleen O'Shaughnessey as Red Alert, a female medical autobot who is stationed with Ultra Magnus in the sanctuary and is now considered to replace Ratchet as the new medical bot off this sequel trilogy
Josh Keaton as Hot Rod, a rookie autobot who is stationed with Ultra Magnus in the sanctuary
Bill Murray as Kup, a veteran class autobot with a great memory of cybertronian history who is stationed with Ultra Magnus' crew in the sanctuary they were given
the Dinobots, the fan favorite band of autobot allies who finally make their debut in the Transformers cinematic universe who in the original series were created but here in the films they were already built as legendary warriors much fierce but much more intelligent than they were in the cartoons
and for new autobots for KSI to build in means of making up to the world for the mistakes the company had made in the previous movie, the autobots that they should create are the Aerialbots
after all the people in charge of the film's cannot keep holding back on anymore of the good kinds of robots and sticking with just robot piloted fighters. Plus with all the war ships that we saw in Age of Extinction that were dropping seeds down on the dinosaurs, Transformers 5 is the perfect time to bring out the Aerialbots with Silverbolt voiced by Robert Redford
together they all combine into Superion
then the Decepticons
Frank Welker as Galvatron, the reincarnated leader of the decepticons. After the events in Age of Extinction, Galvatron will be sure to have rallied with some of the other decepticons who have survived being hunted by Lockdown and Cemetery Wind.
Steve Blum as Blitzwing, the decepticon Triple Change who transforms into both a jet and a tank and is expected to appear as part of the new major line up of decepticon replacing Starscream
Mark Rolston as Cyclonus, one of Galvatron's elite commandos who is expected to last for the next two films and replacing Soundwave as Galvatron's most loyal lieutenent
Miguel Ferrer as Scourge, another one of Galvatron's elite commandos who will be replacing Shockwave
Eva Green as Airachnid, a female member of the decepticons Galvatron rallies with, and since Eva Green is becoming more frequent on playing villainess roles in certain movies like Dark Shadows, 300 Rise of an Empire and Sin City a Dame to Kill For, it's time for her to put her acting skills to the test at voice acting and what better way for her to start than to voice a female decepticon in the films like Airachnid
For new decepticons that can transform and also combine molecularly, the Combaticons
Together this destructive group of decepticons combine into Bruticus
and finally the Quintessons, the race of evil aliens and machines who created the Transformers are expected to appear as the creators that were responsible for causing the great extinction to the dinosaurs and the ones who hired Lockdown to capture Optimus
Surely the most popular among this race, the 5 headed judges are the leaders of the Quintessons. In the films however, there can only be room for one specific leader and the best choice of a villain to lead the Quintessons is Alpha Quintesson,
known for appearing in Transformers Energon, Alpha Quintesson othewise known as Alpha Q would be the best choice to act as leader of the Quintessons and as leader of the Quintessons, he will act as the main villain for Transformers 5 and Benedict Cumberbatch, an actor with the talents of intellects should be the best actor to voice this sinister villain the Judges will be sure to appear as second in command of the Quintessons helping carry ou Alpha's orders and they each of them are sure to be voiced by a few certain actors for each head, including those who participated in voicing characters from previous films like Mark Ryan, Robin Atkin Downes and more
the five faces of the judges represent the most sinister of such negativity in life
while more of the Quintessons are yet to be revealed, some of those who were bombing the dinosaurs with seeds will be revealed
like Transformers Age of Extinction, Transformers 5 is going to need to be about 165 mins to 3 hours long so that we can see more characters appear in the film and where ever the climax to this film will be taking place at, it may regard the city that Galvatron was intending to detonate the seed in
Feel free to get this list over to the director of the film while there is still time
