Cade Yeager

Cade Yeager is one of the three main protagonists of the Transformers film series (along with Sam Witwicky and Optimus Prime). He is the father of Tessa Yeager, the adopted father of Izabella and the boyfriend of Viviane Wembly. Cade is an aspiring robotics inventor with an interest in cars while being an overprotective single father raising his teenage daughter, even forbidding her from dating. Cade helps a disillusioned Optimus, who is dismissive of humanity before, by reminding him that some humans are worth fighting for.
