Prologue: Patricia Wolman talking to her mother on the phone,
complaining about working for Hulk/Doc Green and mentioning that she is going
to her old lab. As she hangs up we learn she has been talking to a recording as
her mother is dead....
Weeks later, Vancouver is being covered by green sentient
vines, turning infected people into green zombies. As Hulk (a/k/a Doc Green)
monitors the situation, his colleagues appeal to him for help. Soon Hulk is
dropping from an airplane and trying to analyze the monster growth but a giant
vines smacks him a couple of miles away. He fights back and then discovers that
the plants a made from his own DNA and they remind him of the creations of Dr
Derenik Zadian (see THE INDESTRUCTIBLE HULK ANNUAL #1). As he fights he
realizes the mass of vegetation is trying to communicate with him—and a huge
field suddenly takes on the face of Patty Wolman, now calling herself Vista....
As a SHIELD agent inform Patty's father that she is dead,
absorbed by the ecosystem she created, the reader is show her history: as a kid she was concerned with
the environment so she aspired to become a scientist. Her mother closely
supported her until Mom died of cancer; after this Patty threw herself into
her work to hold off the grief even as her father fell into illness and
financial trouble. Patty created Vegetal Intelligence Sentient Transmission
Array (V.I.S.T.A.) but the experiment failed and she lost her funding. She was
diagnosed with a degenerative brain disease so in desperation, she took a job
with SHIELD working for Bruce Banner all the while hoping to uncover the
research of Dr Derenik Zadian, which she eventually did. As her mind started to
go, she fused her consciousness to V.I.S.T.A. and she went mad, her mind
becoming a massive vegetable monster bent on exterminating the human race, her
ecosystem's biggest threat...
...which is where we find Doc Green trying to talk her out of
this, presenting the good as well as the bad of humanity, condemning her
despair. Hulk channels lightning down a copper wire to short her out but her
Hulk DNA causes her to recover. Hulk then unleashes the viral pesticide he had
created which wipes her out. Hulk assures the locals he will help them
rebuild....
Epilogue: On a small island in the South Pacific a boat and
its crew are destroyed by Vista....
