They could make Mandarin very epic if they really use imagination skills to express the power of his rings.
The Makluan rings he wears, which he can command over vast distances, each possess a different ability: “ice blast” (left little finger), to emit waves of cold; “mento-intensifier” (left ring finger), to place people under mental control; “electro-blast” (left middle finger), to emit electricity of various intensities; “flame blast” (left index finger), to project heat and trigger chemical explosions; “white light” (left thumb), to emit various forms of electromagnetic energy; “black light” (right little finger), to create absolute blackness, possibly a form of Darkforce; “disintegration beam” (right ring finger), to break down a target’s molecular bonds; “vortex beam” (right middle finger), to manipulate air for levitation or concussive force; “impact beam” (right index finger), to project explosive, sonic, or magnetic force; and “matter rearranger” (right thumb), to alter a substance’s molecular structure into gas, liquid, or solid form. He has used a wide variety of robots, weaponry, and vehicles.
