Superhuman Strength, also called super strength or enhanced strength, is an ability commonly utilized in fiction.
It is the ability for any creature to be stronger than normally possible given their proportions. Superhuman strength is derived from various mechanisms such as; battlesuits, cybernetics, genetic modification, telekinetic fields, and magic. Many heroes and villains usually have a degree of super strength. The level of strength portrayed can vary greatly, from just outside the "normal" human range of the strongest weightlifters of a given size or muscle mass, to nearly unlimited. In most portrayals, superhuman strength is usually accompanied by superhuman stamina and durability as well.
Luther possesses immense strength, which was further amplified by his new ape-like physiology. As a child, he could easily lift and throw a fully grown adult across a room and through a window. His strength is enough to lift up slightly a farm truck off for Diego trapped leg as a results of at least few thousand pounds he can lift up.
During her fight against Luther, Lila was able to copy his superhuman strength and use it to stop his fist and physically overpower him and throw him outside the house and smash the walls as she did.
