Naveen Khan

Dr. Naveen Khan was a theoretical physicist from Gotham City, who specialized in trans-dimensional technology. At one point he worked for Wayne Enterprises' clean energy division, but was instead obsessed with creating a dimensional portal.

When Shredder arrived in that dimension, he kidnapped Dr. Khan and forced him to work on a dimensional portal so that the ninja lord could return to his home dimension. Forced to work for days without sleep, Khan was concerned about the possible effects of keeping the portal open.

He was rescued from his imprisonment by Batman, who sent him to a nearby boat piloted by Alfred. However, Khan had a subdermal bomb implanted in his head, and Shredder later killed him by triggering it.
