10 Richest Superheroes Of All Time
3. Black Bolt
Source of Income: Terrigen Crystals & Real Estate Assets
Blackagar Boltagon (hell of a name, right?) as ruler of the Inhumans, lays claim to the Terrigen Crystals. These incredibly rare items that have the potential to give people superhuman abilities (if you have the latent Inhuman gene) are valued in the billions.
It's also worth nothing that Black Bolt's Inhuman kingdom includes the moon, parts of the Himalayas and a Manhattan island.
While we shouldn't expect Bolt to go around pawning off Terrigen Crystals, he also has access to the vastly superior Kree technology which would be a much simpler way of liquidating his assets. But, let's be honest, any member of Marvel's Illuminati is ridiculously wealthy.
