Let me be crystal clear about this right from the start: Gilgamesh is currently unobtainable in Anime Vanguards as of October 2025. The critical item needed for his questline - the Inactive Key of Babylon - no longer drops from any stages in the game. This change happened after Update 4.0, making him one of the rarest exclusive units in the entire game.
However, if you're one of the lucky players who still has an Inactive Key of Babylon in your inventory from before it was removed, you can still complete the questline and obtain Gilgamesh. This makes understanding the acquisition process valuable for both historical context and potential future reruns.
Before diving deeper, let's clear up a common confusion. Gilgamesh is a unit, not a familiar. However, he can be equipped with familiars just like any other unit in the game. Here's what you need to know:
Vanguard Familiars are special equipment items that provide massive buffs to specific units. Each Vanguard Familiar is tied to one particular unit and cannot be used by others. For example:
As of 2025, there is no specific Vanguard Familiar for Gilgamesh. However, he can be equipped with any regular familiar to enhance his already incredible stats. Based on community testing, the best familiars for Gilgamesh include:
For those with an Inactive Key or hoping for a future rerun, here's the complete step-by-step process:
The Inactive Key of Babylon used to drop from two specific locations:
The key had approximately a 10% drop rate, with a pity system guaranteeing it after 10 Kiro kills. Players would typically farm Golden Castle Legend Stage 2 as it was more efficient.
Once obtained, you needed to:
With the Active Key, you had to defeat three specific bosses in order:
The ultimate test was defeating Gilgamesh himself in Golden Castle Act 3. This boss fight required:
Upon victory, the Active Key awakens and Gilgamesh joins your roster!
Evolving Gilgamesh into his ultimate form requires extensive resources:
King of the World (Passive)
Gate of Babylon (Active)
Myriad Treasures (Passive Enhancement)
Enuma Elish (Ultimate - Unlocks at Upgrade 10)
Despite being unobtainable, Gilgamesh continues to dominate tier lists for several reasons:
Unlike other exclusive units, Gilgamesh pairs exceptionally well with:

With trading supposedly coming "soon" since Update 2.0, Gilgamesh's value continues to skyrocket. Community speculation suggests:
Stay informed about potential Gilgamesh returns:
Based on developer patterns and community feedback:
No, Gilgamesh is currently unobtainable unless you have an Inactive Key of Babylon from before it was removed from the game.
While not confirmed, exclusive units have returned during special events. The developers haven't ruled out future availability.
Vogita Super offers similar AoE damage, while The Struggler provides comparable boss-killing potential. No single unit fully replaces him.
Absolutely. His unique abilities and exclusive status make him one of the most valuable units for both collection and gameplay.
While incredibly powerful, he performs best with proper support. Solo carry is possible in early-mid game content only.
Currently, no Gilgamesh skins exist. If added, they would likely provide the standard 25% damage boost in specific modes.
The developers haven't explained this decision. It may be for balance reasons or saved for future content.
Despite power creep, Gilgamesh remains top-tier due to his unique mechanics and versatility. Only 3-4 units match his overall utility.
Gilgamesh stands as one of Anime Vanguards' most legendary units - a testament to perfect game design that balances overwhelming power with strategic depth. While currently locked behind the unavailable Inactive Key of Babylon, his impact on the meta remains undeniable. Whether you're a veteran player optimizing your Gilgamesh build or a newcomer learning about what you missed, understanding this unit's mechanics prepares you for his potential return.
The combination of his immunity to status effects, scaling damage bonuses, and instant-kill mechanics creates a unit that excels in every game mode. His synergy with Fate units, particularly Saber and Ishtar, showcases thoughtful design that rewards thematic team building while maintaining competitive viability.
For those without Gilgamesh, focus on building strong alternatives while saving resources for his potential return. The game's evolution continues, but few units have matched the King of Heroes' blend of style, power, and strategic importance. Keep watching official channels, as his return would undoubtedly be one of 2025's biggest Anime Vanguards events.
Until then, may your summons be blessed, and perhaps one day, you too will command the Gate of Babylon!
