The Battle at Ivo Tower was a fight in the episode Let's Go to Ivo Tower, You Say between Superman and Parasite.
Tech billionaire Dr. Anthony Ivo, CEO of AmazoTech, invited people to Ivo Tower to present his new project, a suit of armor codenamed "Parasite 1.0". The people of Metropolis, according to Ivo, live in dangerous times. Metropolis used to be the safest city in America, but now, it's plagued by a severe crime wave and Superman cannot be trusted. Ivo says that with his Parasite suit, anybody can be their own Superman. As a demonstration, he attempts to throw Curtis out of the building.
Superman quickly arrives to the tower, saves Curtis and asks Ivo to let the guests go free, but Ivo just tells Alex to seal the room with an energy field. He uses his suit to attack Superman, explaining that the suit grants the wearer with strength, speed and durability similar to those of Superman, and if the suit takes damage, it can absorb kinetic energy and redirect it. With the suit, Ivo can take Superman's attacks and return them with even greater strength.
To help Superman, Lois and Jimmy infiltrate Alex's control room, incapacitate Alex and deactivate the energy field imprisoning the guests. Superman keeps his distance from Ivo, dodges his attacks and allows his opponent to exhaust himself. The suit malfunctions and Ivo is left horribly disfigured and is taken to the hospital.
