Easter eggs in Heroes.

You can play against him on my map at this link. You can also use him in two maps that are currently being planned. You can add this hero to a map yourself using the editor: select any hero and go to MapPropertiesThree, find the Shared tab, click “...”, and choose the hero from the list (there will be a tab with heroes somewhere at the top; we need it for creating videos). His name there is "Timerkhan." :)
