Tony Stark could use his intelligence to analyze the BAMF's weaknesses. He might quickly run scans during their encounters to figure out what can harm the BAMF. Then, he could upgrade his Iron Man suit with new weapons and defenses specifically designed to counter the BAMF's attacks.
Tony could go back to the drawing board and create a whole new line of suits. He might draw inspiration from his past experiences and the BAMF's attacks. He could also study the BAMF's fighting style and abilities more closely. Maybe he discovers that the BAMF has a weakness to a certain type of energy, so he builds a suit that can harness and direct that energy to fight back.
One possible plot could be that the BAMF is a powerful new villain who targets Tony Stark out of jealousy for his technology and fame. The BAMF might start by attacking Stark Industries, causing chaos and destruction. Then, they could directly confront Tony in his Iron Man suit, using some new and unexpected powers to hurt him both physically and mentally, perhaps by hacking into his suit's systems.
