Venusaur first appeared as a Bulbasaur inside. Edge went to Professor Oak's Laboratory in hopes that the professor would teach him how to be a great Pokémon Trainer, and found a dark, empty laboratory. In one of the on an empty table was Bulbasaur. soon entered and startled Edge, causing him to accidentally release all of Professor Oak's Pokémon from his lab. Edge was ordered to retrieve Oak's Pokémon, and Bulbasaur was the last one to be found, in the closed. Bulbasaur was scared, but Edge used calming words to gain his trust, which caught Oak's interest, as in the past, Bulbasaur was disobedient to the level of using on him. Disaster struck though as a wild appeared and attacked them. When all bets were off, Edge took a wild guess and presumed that with the giant seed on Bulbasaur's back being his key trait, exposing him to rays of sunlight would be worth an attempt. He opened the curtains on the window, allowing him to use and defeat the bulky Pokémon in a flash. After the battle, Professor Oak saw the bonding occurring between Bulbasaur and Edge, as well as the fact that Bulbasaur had learned how to use Solar Beam, and allowed Edge to keep him, along with a.

An injured girl is being attacked by an enraged, with her defending her. Staryu nearly faints as Edge appears. Edge decides to help with his Bulbasaur. Thanks to the type advantage, Gyarados's doesn't critically injure Bulbasaur. Edge then commands Bulbasaur to use, which drains some of Gyarados's health. However, Gyarados breaks free of Leech Seed due to sheer force, but Bulbasaur and Staryu's combined and, respectively, finally manages to weak Gyarados enough for Edge to use the girl's  and recall the rampaging Gyarados.

Inside the, Edge is taken by surprise by an eerie fog that begins to mysteriously form. A suddenly appears from the mist, soon followed by other Pokémon, and as Psyduck draws near Edge, discovers that Psyduck is really a ghost. The other ghosts, along with Psyduck, prepare to close in on Edge. Bulbasaur is quickly sent out, and after a few unsuccessful attacks it manages to crush the decomposing Psyduck corpse with, causing Edge to vomit due to the disgusting sight. As the other undead Pokémon close in on the duo, Edge and his Bulbasaur make a dash for the exit, but Edge notices that the ghosts aren't following them. Noticing that the ghosts are not leaving the fog, Edge deduces that the corpses must be controlled by the fog, just as he sees a blast of fire coming at him. Dodging the attack, Edge recognizes Robyn's silhouette, but as he tries to run over to them, Robyn's continues to attack. When he gets a closer look, he sees that there is something different about Robyn's expression, as the latter stands alongside the ghosts in the fog.

Edge calls out to Robyn, but quickly realizes from the latter's eyes that his rival is being controlled by the mysterious fog of the Tower. While Bulbasaur fights the possessed Robyn and his Charmeleon, Edge deduces that Robyn is being controlled by a and tries to stop it by having Bulbasaur use. Due to Gastly's gaseous body, the attack simply goes right through, and Charmeleon gets ready to subdue Bulbasaur with a massive attack. Quickly, Edge has Bulbasaur use the bulb on its back to suck in the Gastly and the fog it created, freeing Gastly's possessed victims before expelling Gastly in a.

Edge rouses Robyn from his stupor, but much to Edge's surprise, Robyn heads further into the Tower, determined to find the individual responsible for turning him into a mindless slave. On the way up, Edge barely avoids touching the corrosive venom from a Pokémon, and at Robyn's demand, the culprit reveals himself to be ; an elite agent of. Koga reveals that Team Rocket had been using the Tower as a base of operations, and thanks to the townspeople fear of the Tower they had managed to carry out operations undisturbed. Robyn has his Charmeleon attack Koga; however, it proves to be only a projection, with the real Koga controlling his Pokémon from elsewhere.

Koga sends his after Edge and Robyn, who quickly unleashes its corrosive. The boys run back to where Edge had encountered the zombies, and Robyn orders a from Charmeleon. Outside the tower, Koga observes the battle from a -shaped screen, and commands another Acid that appears to break past Charmeleon's defense and corrode it as well. Koga gloats at his victory, but is soon surprised as Charmeleon Arbok cleanly in two. Robyn explains that Arbok had instead melted the Psyduck corpse from earlier, and points out that Koga's strategy of controlling his Pokémon from a distance meant that he couldn't see through the substitution ploy. Edge silently concedes Robyn's skill while Koga, crushing his screen in anger, swears vengeance on the two boys.

During a battle against a wild, Bulbasaur evolves into Ivysaur and uses its newfound power to defeat Primeape, much to Edge's delight. Sol, distracting Edge with fake applause for this evolution, sold Edge a bunch of fake items that did nothing but hinder him. Edge proceeded to give chase on Sol to get his money back, while Sol used the opportunity to steal Edge's two Badges. However, a chain of events unfolded in the that left Edge (disguised as a ) and Sol allied. Ivysaur's was used to try to capture the  that appeared before them.

Later, Ivysaur is accidentally traded to Robyn Oak alongside Azumarill and Pikachu. During the three days that Robyn had them, Ivysaur and the others train vigorously. They later traded back, while keeping the serious attitude that Robyn installed in them.

Ivysaur was the first Pokémon chosen by Edge to battle against and her. He commands Ivysaur to use and reel Tangela in, but Tangela tosses Ivysaur away with little effort and defeats it.

Having just returned from, Edge decides to pay a visit, but is somewhat perturbed by the apparent lack of activity in town. In, Edge begins to ask Professor Oak about his inability to enter , when the Professor starts attacking all of a sudden. In response, Edge releases Ivysaur to restrain Professor Oak with, but Professor Oak surprises them by exhibiting signs of power, and attacking Ivysaur with a. Recognizing the handiwork of a Psychic Pokémon, Edge orders a from Saur, and as the "Professor's" energy is drained away it reveals itself as a, which had been using its Illusionary  powers on 's command. As the herself appears, she graces Edge with a warning before teleporting away: the Professor, along with the townsfolk, were kidnapped and held hostage in Saffron City. Before she teleports, Ivysaur uses, but it goes right through Sabrina without doing anything to her.

Ivysaur later battled against and  at. Ivysaur's attempts to fight back with Razor Leaf seemed hopeless until Edge had Ivysaur redirect the leaves it scattered from his Razor Leaf at Lt. Surge and Zapdos. The attack not only severs the wires directing Zapdos's electric power away from Surge, but also ruptures the 's insulated suit, giving him a crippling dose of Zapdos's electricity that promptly knocks him out cold.

Ivysaur, Robyn's Charizard, and Sol's Blastoise battle against the of Zapdos,  and. During the attack, Ivysaur evolves into Venusaur, which tips the scales of the battle towards the three starters's favor, and eventually defeats Sabrina and also separates the conjoined.

The rivals Edge and Robyn begin their much-anticipated battle for the title of the, with , , and Sol among the excited audience. A simultaneous drop of their Poké Balls reveals Robyn's and Edge's Venusaur, much to Bill's shock as the odds are stacked against Edge. Taunting Edge for a misprediction, Robyn orders a that Venusaur barely dodges, but as Charizard lunges in for a follow-up attack, Venusaur surprises it with a burst of. Edge follows with a that Robyn is forced to assist his addled Charizard in dodging, before Edge switches for Snorlax to continue.

Later, much to the horror of the spectators, Edge makes a switch back to Venusaur, which causes Bill to become angry at Edge for his decision. Mocking the sentimentality of Edge to finish the match with the Pokémon they received from Professor Oak, Robyn sends in Charizard for the kill when a Vine Whip securely binds Charizard. Robyn is surprised at the presence of a cloud in the arena, to which Edge explains that Azumarill and Pikachu had formed the lightning cloud when they were flung up to the ceiling; Azumarill's water was super-heated and condensed in midair while Pikachu electrified the cloud. With Venusaur's vine acting as a lightning rod, Charizard is not only trapped but severely shocked by the combination attack of Edge's three closest Pokémon, and as the smoke clears, Charizard eventually collapses.

Personality and Characteristics
Prior to joining Edge's team, Venusaur was incredibly shy and timid, due to the fact that it had never interacted with other humans besides, but quickly warmed up to Edge and became one of his most trusted and reliable Pokémon.

Over time, Venusaur outgrows his shyness and timidness, and adopts a more feisty, but also immature and mischievous personality, being easily annoyed by things that doesn't interest him, and occasionally liked to pull pranks on his fellow Pokémon. However, after evolving into Ivysaur, and subsequently Venusaur, his personality changed: He became more focused and serious, but still retained its immature personality whenever it had free time, but stopped pulling pranks on others. After his evolution into a Venusaur, he became one of the major powerhouses on Edge's team.
