Super strength, from a Human perspective, was a super power that was possessed by anyone who had strength beyond the peak of what was considered Human-level strength. This means they were stronger than the strongest "normal" Human.
Many Metahumans and alien species could've thus been classified as having super strength. There was a wide range of super strength. It ranged from a level of super strength that could have perhaps allowed one to lift an automobile over their head, to someone strong enough to knock a planet out of orbit.
