If this applies to you, take caution while reading this section (if you choose to read it at all).
Spoiler warning: The following section(s) contain plot and/or ending details that some people may not wish to learn before reaching this point in the game on their own. Ivan's background is initially shrouded in mystery even from himself, and while his modern-day caregivers are met in Golden Sun, his early life is only revealed late in The Lost Age.
Tri-Elemental (Partial): Ninja class series.Tri-Elemental (Full): Ranger class series, White Mage class series, Medium class series.Dual-Elemental (Partial): Apprentice class series, Page class series.Dual-Elemental (Full): Hermit class series, Pilgrim (Jupiter) class series, Seer (Jupiter) class series.Ivan has the following classes available to him: Fellow Jupiter Adept Sheba, in comparison, seems to have been designed as a less extreme version of Ivan in every field, having quite a bit less of Ivan's agility and having a little less of Ivan's other strong point of PP, but having more in Ivan's sorely lacking HP, Attack, and Defense stats, and she also happens to have 1 additional Luck point. The only way he is not a direct opposite of Garet is that while Ivan has the lowest Attack rating, Garet's attack rating is not quite the highest in either game. Ivan is also one of the two Adepts that has 4 inherent Luck, the other being Jenna. Ivan seems to be a direct reversal to Garet in that they are both Golden Sun's closest characters to "collections of extremes" Ivan has the lowest HP, Attack, and Defense ratings of all the eight Adepts in terms of natural statistical growths, but the highest in PP and Agility as well. This is arguably a point in Ivan's favor, as this allows him to equip the extremely powerful light blades with damage-multiplying Unleash effects, Tisiphone Edge and Masamune. In The Lost Age, Ivan is extremely similar to Sheba in that she is also a Jupiter Adept and thus has the same default class series the main difference between them is that Ivan can equip light blades while Sheba can equip maces. If there is no data transfer used at all, Ivan will join at level 28, with five of the original game's 28 Djinn (instead of seven) Set onto him, and he will be equipped with a Master Rapier, Silver Vest, Silver Circlet, and Silver Armlet. At a late point in the game, Isaac's party joins Felix's as additional party members, and the statistics and inventory of Ivan as well as his companions Isaac, Garet, and Mia are directly dependent on whether you're using data transfer, what level of data transfer you're using, and the actions and levels of progress Isaac's party committed in the previous game. Ivan, like the rest of his party, is absent from your own party as led by Felix for much of Golden Sun: The Lost Age. Ivan also typically has good group buffing spells like High Impact.
While at the endgame, these Psynergies are merely for "softening up" the opposition, earlier on they can be very good at inflicting strong damage to multiple targets.
Also, his high agility allows him to use psynergy before most in a battle, which makes him a volatile caster. While he doesn't easily possess healing Psynergy like Mia, Ivan does, however, have a repertoire of strong Jupiter Psynergy attacks like the Ray Psynergy series and the Plasma Psynergy series. In addition, Ivan has almost notoriously low initial HP, which prompts players to use any HP-boosting Power Bread items on him. Ivan is just like Mia in that he does not possess the attack power to strike with physical attacks anywhere near as hard as Isaac and Garet, for his default class, which players would often play the whole game with due to playing each Adept in their respective mono-elemental Class series, does not have a high Attack modifier. When the player first recruits him into the party he is level 4 (with 194 experience points) and is initially equipped with a Wooden Stick, Travel Vest, Leather Armlet, Circlet, and an Herb. He is the party's resident Jupiter Adept, and his default class series is the Wind Seer class series. Ivan is a character that becomes a permanent part of Isaac's traveling party shortly after leaving Vale to begin the quest in Golden Sun, temporarily joining in the town Vault and very shortly afterwards becoming a permanent party member at the entrance to Goma Cave.
