Topper addresses Mario by stating that, even though Mario stopped Bowser from marrying Peach, he still has to deal with them. The final fight is at the Rabbit Ridge tower at Dark Side. Topper is also one of the pilots of RoboBrood.

In this fight, he uses several hats instead of just three, runs away in panic when all the hats are knocked off, and must be stomped three times. He is later fought again in Bowser's Kingdom. After he is hit at this point, Topper is defeated and falls to the ground in a daze. From here, the attack pattern starts over, with the exception that Topper now panics and runs instead of sitting stunned when his head is exposed. At this point, Mario must hit the hat he is in to stop him, with the other hats again providing hearts. After he is hit, Topper will hide in one of his hats, and all three will bounce around like shells. He can also be attacked directly while he is spinning along the ground. Once all the hats are removed, Topper will be stunned, and Mario must attack the top of his head. This attack can make him dizzy, giving Mario a good opportunity to strike. He also has an attack where he spins along the ground level with the hats on his head. Mario must knock off his hats using Cappy to damage him once knocked off, the hat will slide around spinning like a Koopa Shell, and can be hit for one heart each. In battle, Topper stacks two copies of his hat atop his regular one before skipping towards Mario. Topper is introduced and first fought at the Cap Kingdom in Super Mario Odyssey.
