Hulk
The Hulk's adaptability is primarily reactive and physical. Exposure to extreme environments triggers biological modifications: underwater breathing when submerged, radiation absorption when bombarded, increased density when crushed. He has developed multiple personas—Savage Hulk, Professor Hulk, Joe Fixit—representing psychological adaptations to trauma. Yet fundamentally, his solution to every problem remains remarkably consistent: overwhelming force. When your only tool is gamma-powered fists, every problem resembles something requiring smashing.
Money
Money's adaptability borders on the supernatural. It has transformed from physical commodity to pure abstraction, existing now primarily as electromagnetic signals in server farms. It adapts to inflation through interest rates, to scarcity through fractional reserve banking, to borders through cryptocurrency. The $2 trillion daily cryptocurrency market represents money's latest evolutionary leap. It can become liquid or frozen, visible or hidden, legal or laundered. Money flows around obstacles like water around stones, finding every crack in every system ever devised to contain it.
