|~ Joshua Joyce to Optimus Prime|
Joshua Joyce is the anti-hero of the 2014 film, Transformers: Age of Extinction. He serves as the tertiary antagonist turned supporting protagonist.
His overall role is considered more of an anti-hero than a villain, as he initially had good intentions and had redeemed himself after his Transformers development project went wrong. This may be the fact that he realized that Attinger has manipulated him for a delusional and selfish purpose while finding out that Galvatron was not who he seems and had actually covered his true nature in order to claim the seed.
He is portrayed by Stanley Tucci, who also portrayed Lord Roderick
Joshua is the arrogant CEO of KSI. His company was hired by retired CIA agent Harold Attinger to build artificial, remote-controlled Transformers due to Attinger planned to hunt down the Autobots. Joshua himself thinks the Autobots are only junk compared to his creations. This was shown when Cade, Optimus Prime, and rest of the protagonists and Autobots talk to him for the first time, Joshua openly told them that the Earth no longer needs actual Autobots anymore. However, when he uses Galvatron to capture Optimus Prime, Galvatron is briefly out of control due to Megatron's possession. Despite this, he thought that it is just a technical problem.
Afterwards, Joshua slowly has a change of heart after briefly conversing with Cade Yeager who tried to warn him of who Galvatron really is from what he learned from Optimus Prime along with the Seed that Attinger covered all this time. This made Joshua start to see Attinger for who he truly is based on the knowledge Cade gave him, in which he reminded him of mistakes that he had done. He confronts Attinger to question their mutual cooperation, only to have Attinger reveal that all this time, Attinger has manipulated him as a mere pawn for him (refer him nothing but a golden parachute for his success). Before he even had a chance to cope with all of this, Galvatron reactivated along with other fifty artificial Transformers. He then betrays Attinger, took the Seed away from him, and disobeys Attinger's demand to re-control Galvatron.
A chase ensues in China, where he met with other human protagonists to help him took the Seed away, but is ambushed by both Galvatron's forces, Attinger and his right-hand man James Savoy. He helps the Autobots and Cade Yeager to fight Galvatron and his army. Fortunately for him, just as his hacked Transformers gain the upper hand, Autobots, with help of the Dinobots, quickly overpower them and most of the hacked Transformers are killed, while the rest of them have escaped.
After the battle, he promises Cade Yeager and his family that he'll help them get a new home. He also apparently stopped his Transformers development project after a change of heart.
He is a strict and demanding employer. His ambition made him use his genius to build his own models of Transformers he could control and never be betrayed by them. However his arrogance blinded him to the fact that he was manipulated by both Attinger and Megatron. He's very afraid of death and does not see his mistakes until it's too late. This was shown where he often panics during the battle and chooses to betray Attinger after realizing what he had done and realized that Galvatron has manipulated him. Joyce also proves to be a coward and a hypocritical complainer, whining to Cade and Autobot Hound for involving him into a battle against KSI Decepticons but they retaliate against him by verbally arguing back that at least they are fighting to save Earth while he isn't.
