Background
Isaac hails from the town of Vale at the foot of Mt. Aleph, where he lived a tranquil life with his mother Dora, his father Kyle, and his friends Garet, Jenna, and Felix until a tragic incident at age 14 – the crash of a giant boulder from the mountain into the town below – caused the presumed deaths of Kyle and Felix, along with Felix and Jenna's parents. Though under the influence of his personal loss since, Isaac had coped with his loss quite well and would have lived an otherwise uneventful life were it not for a major twist of fate that would link Isaac's destiny to that of the world of Weyard itself.

In Golden Sun
At age 17, when Isaac joins Kraden along with Garet and Jenna in Kraden's unauthorized investigation into Sol Sanctum, he and Garet witness the arrival of the menacing Saturos and Menardi and their accomplices Alex and, more alarmingly, Felix. This new group takes Jenna and Kraden as their hostages and forces Isaac to give them the Elemental Stars necessary to initiate the return of the force known as Alchemy to the world. As Saturos' band flees the area, The Wise One, the guardian of Alchemy's seal, emerges. The Wise One explains that the restoration of Alchemy can have potentially disastrous consequences for all, and he therefore gives Isaac the great responsibility to pursue Saturos and Menardi and defeat their party objective to activate the four Elemental Lighthouses that will open up Alchemy's seal. Thus does Isaac set out on an epic journey across Weyard as the leader of a group of friends that include Garet, Ivan, and Mia. Although he pursues his objective valiantly, and in fact is able to ultimately slay Saturos and Menardi in a climactic confrontation atop the aerie of Venus Lighthouse, two of the Elemental Lighthouses are nonetheless activated, and Felix and Alex continue their quest in Saturos’ stead.

In Golden Sun: The Lost Age
However, what Isaac had not realized about the Wise One's decree was that the Wise One's description of Alchemy's potentially harmful effects was an intentional half-truth meant to disorient Isaac. Though Alchemy can indeed be a deadly commodity when used for evil, it is actually the force that sustains the world's life force and therefore has to be returned to ensure humanity's survival. The idea behind the Wise One's half-truth is that if Isaac is truly strong in soul yet understanding in heart, he will come to understand the importance of Felix's mission and join him in returning Alchemy to Weyard, in effect demonstrating that he can put the welfare of the world over the need to blindly follow the orders of a higher-class being. This is just what happens when Isaac confronts Felix afterwards and demands answers to why the latter thinks Alchemy's seal must be broken. Felix's explanation reveals to Isaac the truth about the necessity of restoring that force, and Isaac willingly joins his rival's effort to save the world from eventual collapse. In joining Felix, Isaac defies the Wise One just as the Wise One had been hoping.

When Isaac and Felix's combined party of friends and warriors travels to the top of Mars Lighthouse to activate the final beacon together, the Wise One appears and admonishes Isaac for disobeying his command, but Isaac challenges the Wise One's credibility with the truth he learned about Alchemy and explains how that is the reason why he would break the seal against the Wise One’s command. The Wise One in response summons the Doom Dragon to battle the Adepts, and Isaac can tell right away that the dragon is actually a conglomerate of his own father, Kyle, and the parents of Jenna and Felix, the ones the Adepts had hoped to reunite with after their long journey, but in the greatest demonstration of his character Isaac takes up his sword, joins the battle against the dragon, and slays the dragon with his own blade, in effect sacrificing what he holds dearest to his heart for the greater good of humanity. With this, he passes his ultimate personal test in the eye of the Wise One. Once Alchemy is returned, Isaac's body unwittingly absorbs part of the power of the Golden Sun, and he is proven capable enough in the Wise One's eye to take on an even greater responsibility than ever before: to ensure that, throughout the world, Alchemy is not used for evil.

Fan influence
In the Golden Sun fan fiction community, Isaac is most often depicted in a Mudshipping scenario, romantically involving him with Mia. Halfways close to Mudshipping in popularity, however, is Valeshipping, which depicts him with Jenna, and both are from Vale.
