MOMO needs to do that, or else his country will be blown up by kaido.
Also, there is room for interpretation, if MOMO needs to create clouds that are stronger than the current cloud states that Kaido created, which have weakened.
But I have no problem with MOMO creating the clouds, since when do I care about plot armor?
Will ODA actually let the island land and explode killing thousands of civilians when he can't even kill POUND?
And at this point, it's not just the lives of the people in the capital that are in danger, the lives of almost everyone at the summit are at stake if ONIGASHIMA lands, so MOMO had better make it, as he's indirectly wearing the armor. of the plot of all SHS in the castle.
