Mythical Gigas Guide in Persona 3 Portable

Where and When

You meet this boss on floor 160 of Tartarus. You will only face one opponent, meaning it’s a bit more powerful than usual. By this point, you will have flexibility about who to bring to the battle.


This boss is Level 48 with 2100 HP and an extremely high endurance stat.

Strengths and Weaknesses

This boss nulls Light, Dark AND Pierce attacks while draining Fire, repelling strikes, and being strong against slashes. It has no weakness to exploit.


Using Attack Mirrors can really turn the tides in this one as they will reflect some strong attacks.

The ideal team is MC, Yukari, Akihiko, Ken as you can have two healers and two members dealing damage with electric attacks.

The MC can make the difference in this one with clever Persona usage and skills. Urubellos is a strike-resistant Persona who can withstand a lot of the Gigas’ attacks, this Persona can also get the Fire Break skill to take away the Fire draining ability of the boss.

Undoing the enemy’s Marakunda debuff will help keep your team alive as having a lower defence makes you susceptible to its strongest attacks.
