If you’re not quite there yet, this guide for how to unlock the secret characters will help you out.

The Importance of Infinity Trials

Infinity Trials are missions that allow you to earn rewards like XP cubes, costumes, and secret characters in Marvel Ultimate Alliance 3.

As you progress through the game, you automatically unlock the first set, but there are a total of four. You must find the other three while playing through the story mode and finding them off the main path.

Each of these four sets of Infinity Trials contain a secret character for you to unlock by beating a specific trial. These tend to be more difficult than the others because they require a higher level and the completion of previous trials to unlock them. They are also plain difficult missions that require fighting multiple bosses.

Elektra

The characters are obviously going to be unlocked in the order of appearance in which you deal with them in-game. Elektra is up first.

You can unlock her by completing enough Trials to get to Ultimate: Bad Business in the Gamma Infinity Rift.

You complete it by defeating Kingpin, Ronan, and Juggernaut. Its Trial level is 30, so you will probably have to be halfway through the story mode to unlock her unless you’ve been leveling through Trials. Elektra unlocks at level 30. 

Magneto

Up next in Marvel Ultimate Alliance 3, we have the mutant master of magnetism himself, Magneto.

You can unlock him by completing the Trial Boss Wave: Defeat Klaw and Two Bosses in the Psi Infinity Rift (unlockable in chapter 5).

This is a level 38 Trial where you face up against Klaw, Kingpin, and Doctor Strange. Just like the trial level, Magneto is unlocked at 38.

Loki

Everyone’s favorite trickster god is the third secret character.

You unlock Loki by going to the Sigma Infinity Rift (unlockable in chapter 9) and completing Boss Wave: Defeat Ebony Maw and Four Bosses.

It is a level 45 trial. You face Ebony Maw, Supergiant, Cull Obsidian, Corvus Glaive, and Proxima Midnight one after another in that order. Loki unlocks at level 45.

Thanos

This top dog can only be unlocked by going to the Lambda Infinity Rift (unlockable by beating the main story) and completing Ultimate: The Black Order. It is a level 65 trial, so you will have to have a seriously leveled team to even consider trying this as it’s likely the most difficult Trial you’ll face in the game.

You have to fight Ebony Maw, Proxima Midnight, Corvus Glaive, Cull Obsidian, and eventually the big man himself, Thanos. After completing this, you unlock a level 80 Thanos.
