What does each mythic do?

Mythic roles

While mythics are extremely strong units, more mythics does not always mean easier wins. Every mythic in the game serves one or more roles. This is not a deep dive into all the mythics that fit each role, but rather a quick overview of those roles.

Wave Carries

These are the most popular mythics in the game because their strengths are immediately obvious as soon as you get them. Batman and Rocket Chu are two examples of this. Any mythic that clears groups of enemies with AOE attacks, these are Wave Carries. Some are good for the whole game, some are only good for the first 20 or 30 waves. But these are required to survive the main waves.

Below are some popular wave carries. The ones on this list can beat normal mode without any help from boss killers.

Boss Killers/Dungeon Clearers

These mythics don't always stand out right away as being particularly effective. In normal mode, you often won't even need them. But when it comes to taking down bosses, clearing the dungeon, and even just taking out your hunts more easily, that's where you'll use these. The two most popular are Lancelot and Vayne. Note that Lancelot can't clear dungeon effectively. Both of these seem weak at first . However, when it comes to boss killing power, Lancelot is currently the strongest in the game. Vayne is a solid option as well as long as you build up your defense reduce and upgrade mythic damage.

Note that there are wave clears that can do good damage to bosses and dungeon. This is not true for all of them though, and you should try them all out. Notably, Batman is great for a big portion of hard, but he won't put much damage on the wave 80 boss at all even with damage reduce. Try them out, but the strongest one is currently Lancelot.

If you're trying to beat hard mode and you're getting stuck on bosses, these two mythics are particularly good at killing bosses on hard mode:

Support

Support mythics do other things than dealing damage. Some are strictly support, like Kitty Mage. Some are hybrid, like Iron Meow. But they add a different value to the team. Kitty Mage and Iron Meow increase MP Regen. Monopoly Man gives lucky coin generation and Defense Reduce. Stun mythics also belong here, such as Orc Shaman.

The most popular, and most powerful support units are currently:

Conclusion

These are the main roles in the game. Keep them in mind when choosing between mythics to summon. If you have Wave Clear covered, consider trying to get more boss focused DPS. If both are covered, you can scale them into the late game by adding some support units. Try different blends of units. Even months into the game you're likely to find units you had thought were useless in the past are good under the right circumstances. Understand the full kit of mythics and you'll find the game leans less on luck, and more on an understanding of what to do with the tools you're given.

Good luck!
