During this colloquium, the unnoticed beauty of multiband of iron-based superconductors will be highlighted, including i) emerge of topological band which coexists with superconductivity, leading to the discovery of Majorana zero mode; ii) Interplay of multicomponent superconductivity, leading to the discovery of exotic paring with time-reversal symmetry breaking and fractional vortex; iii) Contribution of Hund coupling towards pairing in this unique class of superconductors.
