Scenario #1 - Easy does it as the strange Rhino appeared from nowhere and suddenly charges on towards Ed. Should it make contact,it is sure good night for him but he had a plan which should work, hopefully. As soon as the Rhino charges, Ed gathers chakra into his palm manipulating it into doton but of more lighter composition, he fixed his gaze on the tip of the horn which he hoped to grab. At arms length the Rhino lunges but with one cautious first touch/horn grab, Ed reluctantly reduces it weight from the horn to the entire body by 100x making it light as a feather and more weightless for him to hold. Ed blows the Rhino away with his breath.
Suddenly he was launched up by a crustacean and with the law of motion he was coming down into its mouth fast! With quick chakra manipulation, he gathered earth chakra into his palm and waiting for the right moment to strike he lands into its mouth (tongue precisely) but with his hands on it he increases its weight by 100x making it stiff and unable move or make any actions. Forming a chidoru, I shatter its jaw as I jump out within the crumbles (Itachi style)
