Let's make this birthday one to remember.

44 years old (Born on July 15, 1980)

Happy Birthday, Mike "Iron" Zambidis! May your day be as powerful and swift as your legendary knockout punches—but hopefully gentler on the cake! From electrifying battles in K-1 MAX tournaments to making jaws drop with those signature left hooks, you've given fans countless memorable moments inside the ring.

May this year bring you even greater success outside of it—perhaps mastering a new sport like competitive gyro eating or showing us that you're also a champion at Greek folk dancing. Whatever awaits you next round (but not another opponent!), have an amazing birthday filled with laughter, fun and kicks only aimed toward joy. Opa!
