Lifting Strength | VS Battles Wiki | Fandom

Lifting Strength is defined as the mass that an individual can lift on Earth. In other words it measures the amount of upwards force a character can produce. As such pushing and pulling feats are also considered a part of this statistic, granted they are properly calculated to account for the difference to lifting. A common case is that the weight of something pulled across a
