1- First image shows that IMU with just a Haki flex did cover the whole sun Realm, did spread it's Haki to all directions and the Haki was strong enough to reach the underworld to the the ground level of it.
2- Second image shows how big ImuSaturn haki flex was when IMU did get summoned to God valley.
3- Third image shows how big was Rocks vs Harald all out conquerors haki clashes, they aren't flexing, they are legitimately fighting.
4-Fourth image shows how big and how much distance Imugunko conquerors haki flex did cover, not even a attack, just a Haki flex and it did cover this much distance and that was Imugunko alone, no clash vs another character just as strong or equal.
