(Batman I #323) - Lucius went over the Wayne Foundation finances and realized they were starting to lose money since Gregorian Falstaff kept underbidding them. He noticed Tim headed out and reiterated that he didn’t want him going out with his new friends at all hours. Timothy said his friends listened to him, unlike his father who was too busy balancing books for the man. He slammed the door when he left and Lucius wondered where he’d gone wrong with his son and how he could get him back on track.

(Batman I #330) - Lucius decided to trail his son, and saw him meeting with Ronald Watkins and his gang, who had a big job lined up. Lucius confronted Tim at home, and Tim said he was leaving home. Lucius tried to follow him, but was attacked and ended up in the hospital. He was visited by Bruce Wayne and Dick Grayson, and he begged them to help his son before he passed out. They changed into Batman and Robin and confronted Watkins and his men in a pool hall. Batman gave Ronald Watkins and his men a beating, warning them that he’d take the kid gloves off if they tried to pull off whatever job they were planning. Watkins was not dissuaded, still planning to blow up the Wayne foundation on the orders of Gregorian Falstaff. Watkins tried to convince Fox that Bruce Wayne was secretly a slumlord, and deserved whatever he got. Batman and Robin confronted them at the Foundation, where Fox had finally decided Bruce couldn’t be evil and was trying to duck out. The Dynamic Duo took out Watkins and his men, and Batman let Tim know he was disappointed in him. Robin told Batman Tim had been manipulated, had no one to turn to, and didn’t need Batman lecturing him. Robin made it clear he wanted a long talk with Batman when the case was over.

(DC Retroactive: Batman - The ‘70s #1) - Talia al Ghul, for her own ends, funded three young men, including Timothy Fox, as the new Terrible Trio. She equipped them with battlesuits and advanced technology, telling them to make a splash in Gotham City. Just like the original version, their gimmicks were based on land, sea and air. Batman responded to a robbery committed after a drilling machine burst through Gotham’s streets. He was confronted by the brand new Terrible Trio. They were new to the supervillain game, and were surprised at the fight Batman gave them, so they decided to flee. Bruce Wayne was scheduled to meet with Lucius about business, but found him arguing with his son. Tim had fallen in with another rough crowd Lucius disapproved of and wasn’t studying for his college finals. Bruce commiserated with Lucius, who told him how hard it was to be a single father. Batman and Alfred Pennyworth used the Batcomputer for research and learned that the original Terrible Trio were all either in jail or dead. Batman responded when the new Trio hijacked the Gotham Marine Society Charity Ball. The Trio’s amateurish ways soon lost the fight, but Shark called in his submersible to ram the charity ball boat, telling Batman he could fight them or keep the ship from sinking. Batman used the Bat-Sub to patch up the hole with foam. He met with commissioner Gordon and gave him a button to push when the GCPD had extricated his sub from the charity ship so it could return to the Batcave. Lucius told Bruce he suspected Tim was one of the Terrible Trio, and Bruce suspected they’d target the Wayne Foundation Annual Skyball atop the Wayne Foundation. When they tried to rob the ball Batman released a smoke bomb and activated steel shutters that trapped the Trio at the ball. Batman fended them off, and when Fox threatened to use a detonator to blow up the ball Lucius knocked him out with a dinner plate and Alfred caught the detonator. Lucius was in despair when they were unmasked and he learned Tim Fox was the Vulture. He pleaded with Tim, asking him what he’d done wrong, saying he’d given him everything in life, and Tim said he had everything he wanted except attention.

(Batman I #333) -Robin and Catwoman convinced Ron Watkins t hand over state's evidence in return for amnesty, admitting he targeted the Wayne Foundation because he was on Gregorian Falstaff’s payroll, not because Bruce Wayne was a slumlord. Tim Fox felt disillusioned with the cause that got him in legal trouble, and Lucius said he loved his son and wanted him back home. Lucius admitted they were going through trying times, but wanted his family to be whole again.
