The following article contains spoilers from I Am Batman #9, on sale now from DC Comics.
The Next Batman's battle against the murderous Manray did not go as Jace Fox expected. Forced to flee from an enemy more twisted than any he's ever encountered, Jace had no choice but to try and track down his mysterious adversary at a later point in time. However, I Am Batman #9 (by John Ridley, Christian Duce, Stephen Segovia, Rex Lokus, and Troy Peteri) showed that the new Caped Crusader is somewhat lacking when it comes to detective work.
Jace struggled to come up with a basic profile on the serial killer, distracted by his own feelings of self-doubt. To that end, he eventually asked for help from someone with better insight. So while his personal detective skills are somewhat lacking of the precedent set by Bruce Wayne, Jace is already miles ahead of the Gotham City vigilante when it comes to reaching out to others when he is in over his head.
Jace's unresolved anger over his defeat at the hands of Manray led to him assaulting an unarmed criminal, and put him into an emotional state that even his family noticed. It also hindered his ability to track down the terrifying villain. Adding to this was the fact that Jace had very few clues at his disposal.
From his perspective, Manray was a very twisted villain who believe himself to be something of an artist. Beyond that he had little indication as to how to track down the criminal. To rectify this, he met with his old friend Hadiyah, asking for her insights on the new villain, under the guise of seeking the information in order to help build a relief fund for the killer's victims.
Hadiyah provided the information Jace needed, informing of him of the origins of Manray's art style, as well as giving a cursory examination of the type of person capable of such brutality. Her input helped the Batman of New York form a profile that led to the discovery of Manray's next target. However, it also highlighted that Jace's training has its limits.
While Jace was taught how to fight, use weaponry, and overcome physical and mental challenges, he was never trained to track down people the way Bruce Wayne does. Jace never learned how to really get into the minds of the criminals he faces, and lacks the skill Wayne has at tracking down and predicting the moves of his enemies, largely due to the fact that he never expected to become a vigilante.
Now that he's in New York, Jace is the city's only line of defense against monsters like Manray. His lack of comprehensive training somewhat hinders his ability to operate as effectively as he could otherwise. This is something he can work on with time, but to his credit Jace recognizes his limitations and has shown that he is not above seeking help when needed.
In this way, Jace demonstrated that he has a skill that Bruce Wayne still struggles to develop. Batman rarely, if ever, asks for help even when he needs it, but Jace doesn't have those same issues. He acknowledges the skills of others and is willing to reach out to them for a different perspective. In this regard, he has effectively surpassed Bruce Wayne's Dark Knight.
