Gandalf
Gandalf's power manifests through divine magic rather than physical force. As a Maiar, he possesses abilities that transcend mortal comprehension - he has battled a Balrog for ten consecutive days whilst falling through the depths of Moria, ultimately slaying the beast atop Zirakzigil. His staff channels energies capable of shattering bridges, repelling Nazgul, and producing light that can blind creatures of shadow. However, the Valar specifically limited his power when sending him to Middle-earth, restricting him from matching force with force against Sauron directly.
Hulk
The Hulk's strength operates on a principle that physicists find simultaneously fascinating and impossible: it has no theoretical upper limit. As Banner's rage increases, so does the Hulk's power output. He has caught falling buildings, matched Thor blow for blow, and in certain comic iterations, held together tectonic plates. Laboratory measurements (admittedly difficult to conduct) suggest baseline Hulk can exert forces exceeding 100 tonnes, with enraged states multiplying this exponentially. One documented instance shows him destroying an asteroid twice the size of Earth with a single punch.
