Kingdom Hearts 3 San Fransokyo Treasures and Collectibles

The Big Hero 6 world in Kingdom Hearts 3.

The last stop on our journey, at least as far as Disney worlds are concerned, is San Fransokyo. It’s home to the Big Hero 6, and presents the player with a semi-open area to play around in. To help you save Baymax, Hiro and Co from the evils of Organization XIII, we’ve put together this Kingdom Hearts 3 San Fransokyo walkthrough. We’ll lead you through where to find Treasure Chests in San Fransokyo, how to free Fred, Wasabi and Honey Lemon from the grips of the Microbots, and more.

San Fransokyo Treasure

Upon arriving in San Fransokyo, it’s clear that not all is well with Baymax and the gang. Let’s take a look at how to proceed.

Arriving in San Fransokyo

Sora on the streets on San Fransokyo.

You’ll start off the San Fransokyo level of Kingdom Hearts 3 by standing on Golden gate bridge.

First off, you need to take out the Heartless on the bridge. You’ll need to use cover shot, and then take on the big bad at the end.

After a brief cutscene you’ll be in Hiro’s Garage. Here you can Save, Shop, and grab the Lucky Emblem on the board. Once you’re ready to head out, talk to Hiro.

The next objective is to run through the rings all over San Fransokyo. It’s pretty simple, and you have plenty of time to do it. Back to Hiro’s Garage.

There’s a Map Chest in this next area, so be sure to grab it. Defeat the Heartless ahead.

Head towards the beacon that Hiro has placed on your map, and then defeat the Heartless. Next up is a Boss Fight.

Dinosaur Boss Fight

The next task is to take on the dinosaur Heartless boss. It’s a simple fight, though you will need to dodge its attacks regularly. When you move in for the kill, aim for the section halfway up its back to do more damage.

After a while, the boss will retreat to the top of a nearby skyscraper. Run up there and attack the enemy’s tail to down it.

After another cutscene, you’ll need to rescue the BIg Hero 6. First up is Go-Go. To save her, make your way to her beacon.

You’ll need to shatter the enemy using the large red ball that can be found nearby. Jump on top of it and walk it into the enemy.

Next up is Fred. You need to free the enemy’s tentacles from the lampposts. Dodge into the posts to break the chains. This will free Fred.

Defeat the nearby Heartless for some nice loot.

Next we have Honey Lemon. Head to the enemy and look for the small areas of colored light. Use the corresponding spells on each one to break them (water for blue, fire for orange, thunder for yellow).

With Honey Lemon freed, it’s time to get Wasabi. Run up the side of the building. Drop down and use a dive attack to break the enemy.

A boss fight now, with the mysterious Darkubes. This fight is simple once you realize you can only do damage to the cube at its core. Spend your time dodging until you can attack this core.

Finally, we have Dark Baymax to contend with. Avoid his attacks while flying after him. Remember to shoot as you go, breaking obstacles and doing damage.

For this final fight, use Interceptor Wing as much as possible, and keep your distance. Once you have downed Dark Baymax you’ll be all done.

You’ll be awarded with the Nano Gear Keyblade.

Treasure Chests

The first Treasure Chest to grab is found in the South Western area of the city.

Treasure Chest number 2 is to the East, atop the tall rounded Skyscraper. It is under the landing pads.

This Lower Ledge can be found on the building across the street from the last Chest.

This one is found to the West of the City, underneath the boundary for the next area.

This one is near the last one, atop the building with billboards on top. It is located in the center of these signs.

There are red lights on this tall structure in the North Eastern corner of the City.

This one is to the North East of the last one, and is found behind two air conditioning units.

San Fransokyo Enemies

There's a wide array of enemies to take down in the Big Hero 6 portion of Kingdom Hearts 3. There's the usual Heartless fodder, and some pretty formidable bosses. Early on, you'l come up against a giant dinosaur Heartless. Then there's the nano-machines which entrap the team. Finally, you'll fight an evil Baymax.
