Carlos Jeremy Lebron (referred to as Commander and Commander Carlos Lebron) is the head of the American Army and Military. He doesn't like Keen having the rights to own Mecha-Cobra, Lazer Znake, Version 3, Queen Quirus, Mecha Tyranno-Zilla and the entire species of Tyrannic Zilla, because he thinks any and all monsters should be destroyed or kept in Area 51 under maximum security. He does not spend much time in his house, always coming late and leaving early. He also doesn't know Keen has a laboratory in the basement he never knew he had (He spends so little time in the house he can't explore it), doesn't know M.I.C.P.O.E. is Mecha-Cobra, and doesn't know he also has the two other mechanized cobras in the lab. He owns a house in Jira City, and one in Tokyo, Japan. His salary consists of $15,000 a month.
Even though Keen and Ana have always asked him what is in Area 51, the Commander has always said there is only planes and crates... but they don't believe that, but they don't think it's aliens or yeti, they have a suspicion about disappeared monsters over the past decades...
Commander Carlos is dressed in a unique blue tuxedo with purple pants and the official Leader Badge. He wears a hat that his wife gave him before she passed away.
Commander Carlos acts like he has no feelings at some times. He rarely smiles and nearly always forgets Ana's and Keen's birthdays. He also doesn't care for Keen and Ana's classes, if he has to go to Tokyo, he will immediately enroll them in the japanese school, Tokyo Upper-Class School (東京上級小学校). Keen has no problem with japanese, but Ana has to take ESL classes. If they have to go back to Jira City, they'll be enrolled in Jira Elementary.
