Alpha (10 in base-11) is an alien coming from the Undecimal planet of the Numberblocks universe. He is on a mission to conquer Numberland (the Decimal planet) and change it from a base-10 planet to a base-11 one, making the Numberblocks have trouble with their maths.
Credits to everyone. Also, I use the NATO Phonetic names for numbers bigger than 10 in base 11+.
