 Seth Rogen as B.O.B.: A mass in which you can't kill made when a genetically-altered tomato was injected with a chemically-altered ranch dessert topping. His greatest strength is to eat anything as well as you can't destoy him. His one weakness is that his change on form didn't give him a brain, making him very dumb.

Despite this, he is an expert martial-artist and takes it upon himself to lead the team in attacks, even if his attitude doesn't always work to their advantage.

Making of the movie
Ed Leonard, CTO of DreamWorks Animation, says it took about 45.6 million hours to make Monsters vs. Aliens, more than eight times as many as the first Shrek. Many hundred Hewlett-Packard xw8600 workstations were used, along with a large and powerful render farm of HP ProLiant blade servers. It had over 9,000 server  cores, to read through the animation. The movie had to have 120 terabytes (120,000 gigabytes) of data to complete. It also had one explosion scene alone having 6 terabytes (6000 gigabytes).

Since Monsters vs. Aliens, all big movies released by DreamWorks Animation will be made in a 3-D format, using Intel's InTru3D technology.
