Keen Lebron is a 14 year-old kid and the youngest (and the one with the highest IQ, at 380) scientist in the real world. He created Mecha-Cobra, and two other robots. He lives in the kaiju Multiverse, one which follows the Heisei timeline of Godzilla (and Zilla). He lives in Jira City, but visits Tokyo once every month. The japanese Global Defense Force trusts Keen and, in fact, they donated Mechagodzilla 2's remains to Keen to build his own robot because they were very impressed with his smarts. Keen goes to an average school because it's easy to learn things... at least for him. He lives with his uncle Commander Carlos Lebron, and his cousin Ana Lebron, in Jira City, in a big house with the basement as Keen's Lab and occasionally goes to Tokyo, Japan.
Keen is in 6th Grade loves fiction. He is an expert in everything fiction, and of course non-fiction, like video games, mythology and history. Everyone is shocked with how much Keen knows about games and fictional characters.
Keen is very serious, very patient, and (Obviously) very smart. He always wants to learn more and loves seeing legendary monsters, (But he obviously doesn't like seeing the Vortaak). He can create, fix, arrange and dismantle almost anything. He practically lives alone with her cousin Ana. He never uses shortened words like "it's" or "that's". He rarely shows emotion.
Keen always went to a normal school since Pre-Kindergarden. A kid called Nicholas has made quick friends with him. He is currently in Sixth Grade. He studies in Jira Elementary in Jira City, and in Tokyo Upper-Class School in Tokyo.
He appears with Mecha-Cobra.
