The better my employees, the less I have to work.

Michael "Big Mike" Tucker is a support character and was initially the store manager of the Burbank Buy More, after the CIA takeover of the business he becomes assistant manager. He is portrayed by Mark Christopher Lawrence.


Big Mike prefers to work, and deal with his subordinates, as little as possible. However, he is also frequently and closely involved with Morgan, Jeff and Lester in the store's plots. When briefly deposed by Emmett as store manager, the other employees show a strong sense of loyalty to him.

He is an avid fisherman and takes breaks during work to go fishing. He is demoted to a Green Shirt after Morgan and the other Buy More employees are tricked into helping make Emmett Milbarge look good in the eyes of Buy More corporate, but returns to being manager at the start of Season Three with a new, innovative view on how to manage the company and life, constantly referring to his inspirational financial school, El Segundo.

Big Mike played college football as a linebacker, forming the "Defense of Death" with friend and teammate Jimmy Butterman (Jerome Bettis), and has inadvertently defeated two Fulcrum agents in season two, Leader and Ned Rhyerson.

He had an affair with Harry Tang's wife, and later, after Big Mike's wife, Gladys, divorces him. He begins dating Morgan's mother, Bolonia Grimes in Chuck Versus the Suburbs. Since then, he has taken Morgan under his wing as his de facto stepson and mentors his professional development.

For a brief period in 1988, Big Mike was a member of Earth, Wind and Fire, naming himself as "Rain." Although he failed at his own musical dream, his experiences led Lester to accept him as Jeffster!'s new manager.

In Chuck Versus the Ring: Part 2 it is revealed that Big Mike is on a first-name basis with Buy More's founder, Moses Finkelstein. When Moses informs him that the Burbank branch is on the verge of closing, Mike holds a "going out of business" sale, courtesy of Lester's scheme. By the end of the episode, the store has been evacuated by Jeff. When Jeff and Lester suggest burning down the Buy More to collect the insurance, Big Mike wishes them good riddance, citing Lester's singing as torture and their antics such as answering phones that aren't ringing.

He returns again in Season Four. He comes back to inform Morgan about his intention to propose and marry his mother, Bolonia. He gives Morgan his ring, a full half carat cubic zirconium, and tells him to return the ring once he has the latter's permission. He also returns to Buy More and works as a Green Shirt, and tells Morgan that he is bursting with pride to see him as the new Store Manager. In Chuck Versus the Cubic Z, a video game called Spy Attack is about to be released, and Buy More receives only a handful of copies of the game for sale.

While Morgan starts working on fail safe plans and attempts to obtain more copies of the game, he also claims that he can handle an angry mob, but can't handle a lifetime of calling Big Mike "dad". Much to his dismay, he fails to get enough copies of the game or to control the angry mob. A riot breaks out, during which, he loses Big Mike's ring. Mike saves the day by successfully taming the crowd, showing his capabilities in terms of crowd control and leadership, which encourages Morgan to promote Big Mike to Assistant Manager. But Morgan is unable to find Big Mike's ring. Mike does not blame Morgan or hold it against him, but rather forgives him, and gives him a hug. Morgan gives him the permission to marry Bolonia.

In Chuck Versus the Muuurder, Big Mike uses the BM costume, which is the Buy More logo. He was then kidnapped and held in a Large Mart storage cage. He was targeted because Jeff and Lester kidnapped the Largemart mascot, Kevin Bacon, a piglet. At the end of the episode, the pig was returned to Morgan just as Big Mike returned on his own. Large Mart then burns the BM costume on their door step.

In the season five episode Chuck Versus the Bearded Bandit, it is revealed that Big Mike is married to Bolonia Grimes.


Mike is portrayed as a man who wants to do a little work as possible - a theme among Buy More employees. Mike would host competitions among his staff, lying to them that they would receive extraordinary prizes such as a new iPhone, and that whoever loses in having the most sales, would be fired.

As of the later half of Season Two, Big Mike has shown to be more understanding and respecting of his employees. This change of his character may have been the cause of Big Mike meeting his new love and Morgan's mother, Bolonia Grimes.

Throughout Season Three, Mike goes as far as to offer himself as the manager for Jeffster!, although quits when Jeff and Lester cause him a lot of trouble in the season three finale. It is assumed that he is no longer the manager for Jeffster! through the fourth season.

In the beginning of Season Four, Big Mike is given the assistant manager position, with Morgan serving as the new store manager. Mike had been trying to propose to Bolonia, and had asked Morgan's permission for his hand in marriage with her. By Season Five they are married.
