Empty Inside vs. S.O.T.A.R. v2 vs. Gehenna 2 vs. Under Pressure

I am the quickest in this battle, so I should be able to get in and out of attacks quite easily. My main focus will be to try to damage Empty Inside with the spinning drum. Avoid S.O.T.A.R. if possible and mainly save the flipper for self-righting. I can use the wedge shape for pushing Empty Inside and Under Pressure into the hazards and house robots.
