What are some common weaknesses or vulnerabilities associated with Mr. Freeze?

Mr. Freeze's primary weakness is his reliance on his cryogenic suit and environment. If his suit is damaged or removed, he is extremely vulnerable to heat and normal temperatures, which can be fatal. His obsession with Nora can also be exploited, as it is the core of his motivation and can cloud his judgment. Additionally, his scientific knowledge, while an asset, can be countered by equally brilliant minds or by disrupting his equipment.
