"Everything's changed for me in the past few weeks. The pain of my parents' deaths... It's still there, but it seems smaller. And there's a new feeling now."

C 02 - Bruce

Bruce meets Susan

At Veronica Vreeland's fourth wedding, Bruce Wayne meets and falls for a woman named Susan Maguire. After dating for a few months, Bruce proposes to Susan and breaks the news to his comrades about giving up the life of being Batman.

A few days later, Bruce and Susan are wed. However, the wedding is interrupted by a call from Veronica asking Bruce for help. Bruce leaves an understanding Susan and arrives at Veronica's flaming house. Bruce manages to find his way through and rescue an unconscious Veronica just as the house explodes. After taking Veronica to the hospital, Bruce talks to Veronica's husband, Michael, who was apparently absent when the house exploded.

Ch 16 - Bruce and Veronica

Bruce looking after Veronica

However, Michael, tailed secretly by Robin and Batgirl, pays a visit to Poison Ivy, his creator. Here, it is revealed that Michael is actually a plant-human disguised with human tissue. Poison Ivy then reveals her plan to attack a sea cruise where the rest of her plant henchmen are, including Susan, who arranged for her and Bruce to spend their honeymoon at.

On the cruise, Bruce gets suspicious about the several coincidences among the people on the cruise and he demands to know more about Susan. After a brief quarrel over Susan's mysterious discretion, the green liquid starts to leak from her head. Infuriated, Susan turns her legs into vines and tries to squeeze Bruce to death, after revealing that she works for Poison Ivy, who is after Bruce's money. Bruce manages to use a nearby lamp to electrocute Susan and escape, using a ladder to trap Susan in the bedroom.

Ch 34 - Struggle

Batman vs Ivy

However, just then, Poison Ivy and Michael arrive on a speedboat, prompting many of the passengers to reveal their plant selves and start robbing their spouses. Ivy is ready to leave the sinking cruise, but she notices Susan is missing. She sends her creations to find her, but the duped victims decide to fight back. Robin and Batgirl then show up in the Batwing and use some tanks of a special chemical to disintegrate the plant people, including Michael. Bruce manages to sneak off for a minute and slip into his Batman attire. An enraged Poison Ivy grapples with Batman just as her sea vines start to wreck the ship in half, causing the cruiser's machines to explode and sink the cruiser itself. Robin and Batgirl manage to board the speedboat with the innocent passengers, but Batman tells them to leave without him. Eventually, Batman is able to throw Poison Ivy aside just as the cruiser explodes into two parts. Batman uses his grapple gun to hold onto the Batwing, but is unable to grasp Poison Ivy's hand in time. Ivy apparently dies in the water, and Batman manages to get a glimpse of Susan looking out of the cruiser's window before it completely submerges.
