Charlotte Pickles was the CEO of Mega Corp for the entire Rugrats series and for a majority of its spin-off series, All Grown Up!. Charlotte's assistant during that entire time was Jonathan Kraskell, who, after their company reorganized, became the new CEO in the All Grown Up! season 4 episode, Lost at Sea, and he wound up firing Charlotte from the company.
- The company has an onsite daycare for the children of employees--Charlotte got rid of it at some point before Mommy's Little Assets before reinstating it and naming Jonathan as the head of it.
- In "Lost at Sea", Charlotte says she knows all of the "unethical" practices and "shady" backdoor business dealings that Mega Corp has done.
