x-hero idle avengers best heroes

X-HERO: Idle Avengers was launched 6 months ago but if you have just started playing it and want to shorten the learning phase and jumpstart your adventure, we recommend that you read our X-HERO: Idle Avengers beginner’s guide. Our article provides you all the basic tips and strategies you need to secure a firm grasp of the game’s basic mechanics and features.

Given the limited resources at your disposal, it is important to be very selective when choosing heroes from your collection to invest resources in. Although there is a reset option to take back the resources you invested in a hero you will no longer use, it has its own costs as well. In this guide, we will be showcasing our picks for the best heroes in X-HERO: Idle Avengers. While each hero’s rarity grade is a decent measure of their value, not all heroes within the same grade are absolutely at par with one another.

Although developers working behind every game that boasts a massive roster of characters naturally make an effort to ensure that balance exists across each unit, some will simply stand out. For this reason, tier lists like this one aim to provide a semblance of order in weighing each character’s overall capacity as compared with all other characters. Note that like all other tier lists as well, our X-HERO: Idle Avengers tier list is subjective.

X-HERO: Idle Avengers S Tier Heroes

These are the top-of-the-line heroes that are definitely worth every bit of investment. While Mythic-grade heroes in X-HERO: Idle Avengers S Tier Heroes are each difficult to pull from the gacha, some of them will be given for free on special events. It will take a while before you can have a full team of heroes within the top rarity grade but you will have more than enough to fill a full team roster eventually. As such, picking from among the top ranking cast of characters become a must, and these heroes are the ones you should primarily consider.
