- “It's working! I've got a dragon!”
- —The Professor
In the second and third games, the Professor is very stout with a large head, teal eyes, grey hair, and eyebrows. He wears glasses, a white lab coat, and black shoes. In A Hero's Tail, he is slightly taller, and his hair and eyebrows have become white.
In the Spyro Reignited Trilogy, the Professor is slightly taller, his fur is a similar color with a darker complexion on his head. His hair is white, and his eyebrows are much bushier and also has two strands on top of his head. His lab coat is more detailed with a collar, pockets, and buttons, and he also wears dark brown pants.
The Professor is an intellectual individual who's always looking for solutions. He's always seen carrying around a pencil and his notepad to write down the coordinates from his studies.
In Spyro: Shadow Legacy, the Professor is, stangely, portrayed as a more scientific mole, having no belief in the existence of magic, despite being around it in the previous games (notably in Spyro 2 and 3).
Spyro 2: Ripto's Rage!
In the Winter Tundra, the Professor was with Hunter, Elora, and Zoe when he was working on a new Super Portal, but disaster struck when Hunter inputted a wrong code, bringing Ripto, Crush, and Gulp into Avalar. After the orbs were scattered around Avalar by Zoe's friends, the Professor decided to bring a Dragon into the world to rid of Ripto when the group heard that he disliked Dragons. He, Hunter, and Elora secretly created a portal in Glimmer. Within time, Spyro came through and decided to help them gather the Orbs, which were used to power the portals.
After Spyro defeated Gulp, the Professor was with Elora and Hunter back in the Winter Tundra. He revealed to have obtained a Power Crystal for the Super Portal, hoping to use it to send Spyro home. But suddenly, Ripto rolled a bomb, and the explosion knocked all the orbs off the Super Portal. Before the Professor can retrieve the Power Crystal, Ripto threatened to turn him into "the world's smartest pile of ashes" if he made any attempts to reach the crystal. Ripto then stole the Power Crystal to be used for his new scepter and locked himself inside of the castle.
After Ripto was defeated, the Professor activated the Super Portal, allowing Spyro to go to Dragon Shores, the place Spyro wanted to go to since the beginning of the game.
Spyro: Year of the Dragon
In the Forgotten Worlds, the Professor gave Agent 9 some training when the Rhynocs invaded his laboratory. After the Sorceress's first defeat, the Professor and Elora met with Spyro, where The Professor later told Spyro that he tried to get to the Dragon Realms, but the book he bought was out of date "by a thousand years." Agent 9 nearly blew a secret Hunter had told them to keep from Spyro, but the Professor was able to distract the Agent 9 by claiming that there was a Rhynoc in a bush.
Spyro: A Hero's Tail
The Professor showed Spyro a video with several Gnorcs and the fallen dragon, Red, and explained that the Gnorcs are mining Dark Gems for their leader, and has even allied with Gnasty Gnorc. The Professor then sent Spyro on his quest, and he requested that Spyro visited Moneybags first. The Professor is notable for helping Spyro activate a machine used to transport him from various realms. He later helped him experiment with another machine that puts him in a ball, so he can adventure through the levels called the Ball Gadget.
The Professor helped Spyro through a hologram after each boss in each realm is defeated. After Spyro defeated Red the first time, the Professor told him that Red's new lair is under a volcano. The mole went on to find Red on his own. When Spyro got to Red's Laboratory, he found the Professor captured by Red and was forced into making robotic minions for the evil dragon. When Spyro was battling Red, the Professor accidentally used a machine to turn Red into a giant-sized dragon. Spyro soon defeated Red, and the Professor shrank the evil dragon down in size and captured him in a jar, mentioning that the shrunken dragon would be of use in his laboratory.
Spyro: Shadow Legacy
When the Calamity struck, the Professor was back in Avalar when he became trapped in the Shadow Realm shortly after helping the Bonebuilders in Skelos Badlands. After being freed by Spyro, and once he bested the Fire Minion, the Professor took Spyro to the Forgotten Realms via air balloon. There, the Professor reunited with his family, Sis, Blink, and Willard, and was surprised by Sis's intelligence when she created a magic detector for Spyro to use.
Spyro: Attack of the Rhynocs
The Professor guided Spyro and Sparx to his Secret Lab and wanted to show them a few surprises, one being a machine that can look through the fabric of space via peephole and the other being his automated assistant Butler. However Butler grew out of control, forcing Spyro to temporarily shut him down with one of the lab's electronic conduits. This unfortunately caused the Professor's Peephole Machine to overload, granting Ripto access into the secret lab. With the Professor's warp device in his possession, Ripto teleported Spyro away and was successfully able to take over the Professor's laboratory.
Spyro and Sparx were then tasked with traveling throughout the Realms to recover twelve 'Hearts,' to open a passage back to the Professor's lab and confront Ripto again. After gaining all the Hearts, Spyro and Sparx entered Chateau Ripto to put a stop to Ripto's plan and save the Professor. They discovered the Professor dangling over a vat of lava within Ripto's throne room. After Spyro and Sparx defeated Ripto, they rescued the Professor and warped back to his secret lab.
