Emojibot

Emojibots are one of the new aliens from Series 10 of Doctor Who, and will appear in Smile. They meet the Doctor and Bill when they time travel to Emoji City, where the two start investigating people who are being turned into skeletons.

History
Emojibots arrived on Earth in the far future on December 4, 3014. They built a new town called 'Emoji City' where the robots made 91,0000,000 copies of themselves. Later in 3019 (the date where the Doctor and Bill go to), the emoji-bots turn evil and start to kill tourists.

Description
The emoji-bots are seen as deceitful, robots who do not like trespassers.
