Only one more guardian battle stands between you and completing the Tziah block of Tartarus in Persona 3 Portable, but Mythical Gigas isn’t going down without a fight. A melee-based battle, this ultra-powerful shadow has early access to some powerful physical attacks, and a poorly prepared team will certainly not get you far in this fight.

But just because P3P’s Mythical Gigas guardian fight is tough doesn’t mean it’s impossible, especially with the tips and tricks we’ve got for you in our guide. For everything you’ll need to take down Mythical Gigas in P3P, the guide below has you covered.
This guide contains minor spoilers for Persona 3 Portable.
Mythical Gigas Battle Setup
You encounter Mythical Gigas on 160F of the Tziah block of Tartarus.
Recommended Party
With Mythical Gigas blocking or repelling all physical attacks, you'll need to rely on ice, electric, and wind magic to deal damage in this battle.
However, with Mythical Gigas also knowing fire magic, it's best to leave Mitsuru behind unless you've countered her fire weakness with equipment.
We suggest bringing Yukari, Akihiko, and Ken to this fight.
Though he has access to efficient damage-dealing skills, Ken is usually best as a healer in this fight. He knows Mediarama innately when he joins SEES, while Yukari won't learn it until Lv. 43.
While Ken is focused on keeping the team in good shape, both Yukari and Akihiko have two of the best magic stats of anyone in your party, which they can use to hammer on Mythical Gigas with their elemental magic skills.
Another strategy that players have found to be effective is bringing someone who knows Fire Break to allow for Junpei and Koromaru to be effective in this battle.
Koromaru learns Agidyne at Lv. 45, and Junpei's Agilao will be an effective combo while Fire Break is active.
Recommended Level And Personas
With Mythical Gigas entering the fight at Lv. 48, you'll want to be between Lvs. 45-50 for a comfortable time during the fight ahead.
We'd recommend putting your protagonist on offense for this fight, as Yukari is available as a back-up healer should anything happen to Ken.
With ice, electric, and wind magic able to effectively hurt Mythical Gigas, you'll need a Persona with good ice, electric, or wind magic. If they can resist one or more physical damage types, that's even better, since Mythical Gigas in P3P is primarily a melee-based fighter.
Though you'll need to be Lv. 48 or higher to fuse it, Dionysus is invaluable in this fight. Not only does it resist slash and strike attacks, protecting your MC against two of the three physical damage types, but it also learns Ziodyne at Lv. 50.

Mythical Gigas Battle Strategy
Since it's got enough affinities and High Counter on top of them to keep it safe from physical blows, you'll need to focus on elemental magic to deal damage.
Ken usually ends up being the better healer than Yukari for this battle, but it's good to have multiple healers anyway for this, as Mythical Gigas is capable of impressive damage outputs.
With Ken focused on healing, keep Akihiko and Yukari on full offensewith their electric and wind skills.
Every few turns, it's helpful to have Akihiko use Matarunda on Mythical Gigas to lower its attack. With so many heavy-damage moves, you'll want that stat as low as possible.
Have your protagonist join the battle with Dionysus to keep them covered against most physical damage while outputting an impressive amount of electrical damage yourself, and Mythical Gigas will go down before long.
