Ivlet

Ivlet is the main antagonist of Petz: Catz/Dogz 2. He is a wolf who was caught doing evil things in the past, resulting in his incarceration.

Role in the story
Victor and the player first meet him sleeping during the beginning of the game's story. After the player completes several quests in Dolphin Coast and South Pawville, the two encounter Ivlet once again at night, where this time he wakes up and has a conversation with them, initially questioning the existence of the Magic Hat at first. Ivlet later tricks the player into bringing the hat in, as a means to prove to him that it does exist. The wolf takes advantage of the moment, by letting the player push it closer. He quickly swipes and wears the hat, enabling him to easily escape prison. From this point on, Ivlet does not have any lines of dialogue throughout the rest of the game.

Disaster and repair
Ivlet begins to wrecks havoc upon Pawville via throwing destructive purple balls of fire. He also casts a spell on several animals in the Zoo as well as Jade Fields, leaving them to escape and become hostile. This overall leads to the player being forced to help the village's residents and repair everything in the process.

At one point, Ivlet freezes a great majority of the water that runs through Whisker Woods. This is soon fixed when the player dips the Warm Stone into a hot spring, then thaws out the waterfall with the Hot Stone.

When everything in South Pawville had gotten fully repaired thanks to the help of the player, Ivlet reappears, scaring the civilians. He unleashes a seemingly endless rainstorm upon the village. This is later rectified when the player finds Apollo's Flower in Dolphin Coast and places it on the central flowerbed.

Becoming pure evil

When the player eventually reaches Sky Heights, Theophilus explains the potential consequences of Ivlet's continued usage of the Magic Hat: The more he uses it for evil purposes, the darker the hat will change, and more evil energy will build up inside him until he finally becomes "pure evil" and threatens to destroy the world itself. In some cutscenes, Ivlet spies on the player while the Magic Hat is a much greyer shade.

Ivlet later casts a spell over Monolith Isle, in which the island is left facing an eternal night, until the player searches for the Magic Mirror, an item that is able to undo the effects of the spell and allow the sun to rise up again.

He makes a brief return in Lonesome Park, where he creates four massive whirlwinds that the player must pass and reach Gongoro Peak. Once the player reaches Bartholomew, they receive the Tornado Ring from him, in which it can seal up all the whirlwinds via throwing a stone at them.

Finale
Once the player returns to Sky Heights and Bartholomew reunites with Theophilus, the three work together to use the Earth, Water and Ice crystals as ingredients for constructing the Magic Shield, and preparing for an upcoming final battle. In response to this, Ivlet takes on a much more ferocious appearance as well as summons the Chaotic Dragon as a minion. The Magic Hat has turned black at this point going forward.

The player fights against the Chaotic Dragon first. By throwing stones at it, the dragon collapses an disappears. Outraged, Ivlet faces off against the player himself, jumps up to stand in midair, and lets out a menacing howl.

In battle
To defeat Ivlet, Beat informs that the player will need to first throw a stone at him, then bark/screech, and repeat this method 4 more times. He normally walks around in a circle when the player hides in one of the magic shields. Like the Chaotic Dragon, his sensitivity level is the highest out of any enemy. He will run towards and perform a diving attack at the player once they exit a shield. Right after, he will howl and teleport to a different location. His health system consists of pink hearts, strangely flipped upside-down.

Final moments
Once the player successfully defeats Ivlet, the wolf returns back to his normal state. A vortex suddenly appears and it sucks Ivlet in. The player, Theophilus, and Bartholomew fortunately make an escape back to Sky Heights when the Dimensional Rift starts to collapse. Ivlet's fate after this point is left unknown.

Trivia

 * If the player hits Ivlet with a stone during the final fight such that he falls off of the side of the rift, then he will jump back up and teleport without taking any damage. The player will then have to hit him with a rock again.
