Blizzard has revealed an eleven-year-old artificial intelligence scientist Efi Oladele and fans are now speculating the character from the "Overwatch" lore could be the game's 24th playable character.

Efi is hailed from Numbani who is a recipient of a "genius grant" and dreaming of building something that can make them safe. She will celebrate her win with a trip with her parents, which is her "first time flying."

The changes in the arrivals board on the Numbani map paves the way to theories of Efi's arrival in "Overwatch". Moreover, there are a number of changes that are present on the arrival board since the "interview" with Efi was posted by Atlas News.

Here is the updated Numbani arrivals board via PVP Live.

-The flight from Moscow is Cancelled.

-The Delayed flight coming from Paris is now On Time.

-The Delayed flight to Tokyo is now changed to Hanamura and is now On Time.

-The 4:00 AM flight to London is now changed to Singapore.Mexico City is changed to Dorado.

-The New York flight is no longer Delayed.Cairo is now changed to Taipei

-Los Angeles is now changed to Sydney.

-The 6:30 AM Delayed flight to London is removed and changed to On Time flight coming from King's Row.

Gamespot noted that the changes might suggest a theory that a character based from one of the incoming locations has flown to Numbani. It could also indicate that something might happen to Efi's flight.

This may also suggest that Blizzard may really add the eleven-year-old genius as an "Overwatch" playable character. For now, the meaning in the flight changes is still unclear.

Another theory is that Efi's proficiency with robotics may result to four-legged spider robot tank and becomes the next playable character. For now, these are only theories and fans will have to wait for Blizzard to drop the next clue.

"Overwatch" is a team-based multiplayer first-person shooter video game developed and published by Blizzard Entertainment. It was released in May last year for the PS4, Xbox One and PC.
