That is what I wanted to show you. When you can wield the impossible...You can create wonders - Sergei
Another New 52-era mentor, Sergei was a Russian inventor who apparently designed military trinkets during the Cold War. His lessons were basically all to do with the creation of various gadgets (so thats where Batman got those wonderful toys!), together with the notion of letting go of the rigid concepts of what is possible and becoming an explorer of the mind. To this end, Sergei (aided and abetted by his bionic monkey, Maxwell) locked a 21-year-old Bruce Wayne in a cavern under The Great Sphinx. Bruce was armed only with devices that were all missing their key components and was thus forced to improvise a way out by breaking the logical rules of engineering. Another wonderful, throwaway character created by Scott Snyder, James Tynion IV and Rafael Albuquerque, Sergeis first appearance was in the Zero Year backup story That One Time, which appeared in Batman Issue 22 (September 2013).
