First of all, before explaining how strong 4D is, I will have to explain the concept of 3D... the 3rd dimension is a plane of existence that embodies everything 3D, every universes that is 3 dimensional, which is why there's multiple layers of multiverse, it's basically an infinite amount of 3D universes and timelines within it... infinite 3D isn't really bound, it just seems to be when you go on a higher existing reality (the 4th dimension), infinitely greater and superiorly complex. when a character is 4th dimensional in term of strength, he or she becomes stronger than the incalculable with a strength beyond comprehension and above numbers themselves. because the 3rd dimension is an infinitely small fraction of the 4th dimension, impossibly smaller than a 4D atom, it simply doesn't exist in that plane of existance. if your character have a strength that surpasses infinite 3D strength, this one is impossibly strong, capable of breaking infinity, lifting infinity or possibly match a
