Billy is a mysterious character in the Foundry. He resides in a mansion above the Earth that is only accessible through various complex means, or a tunnel through the Million Years Dungeon.
|Voice Actor||Morgan Freeman|
Billy is silent, meaning that nobody knows much about him. He appears to like the heroes, and he has some sort of respect for them.
- Billy has become some sort of running gag throughout the Foundry (as referenced in some non-canon works).
