Tim's trained in investigation, biology, chemistry, forensics, escapology, undercover work, photography, surveillance, stealth, acrobatics, martial arts, tactics and a number of other skills that pop up as the plot requires.

He's also an extremely good computer hacker and programmer. He can build electronic devices, but he's stronger on the software side of things.

Because of his training and studies with Batman, he's got the power to pull really obscure information out of his ass. If you need to have someone know the airspeed velocity of both African and European swallows off the top of their head, Tim could be your guy.
