Dr. Stone - Season 4

Senku and his companions finally set off for America in search of corn. However, a dispute arises between Ryusui and Senku shortly after they depart

Maintaining morale will be critical on the long journey to the Americas. Knowing where on the ocean you are is pretty important, too. The crew of the Perseus discuss.

The Perseus lands in the Americas. They first head to Northern California in search of yellow dent corn, but discover a lot more than that.

The search party narrowly escaped enemy machine gun fire. Unfortunately, the respite was short-lived.

Tensions rise as Dr. Xeno makes his introductions to the Perseus.

Stanley orders Luna to infiltrate the Perseus and identify Doctor Taiju. Things go sideways when it turns out to be a little too easy.

Senku had gotten his start in rocket building through an email exchange with Doctor Xeno. Their approaches to science soon diverged.

NASA scientist Dr. Xeno attempts to pick off the leader of the Kingdom of Science.

With the crew on board tending to a severely injured Senku, Chrome's team and Tsukasa's team must join forces to devise a way to infiltrate the enemy's lair.

With Senku still confined to the bed, Chrome's team begins work on the tunnel to Xeno's base.

Ryusui and Senku take to the skies in a science versus science dogfight while Xeno's forces mount a ground counterattack.

Xeno's army attacks and when all seems lost, Chrome and his friends finish the tunnel and capture Xeno.

The team head to the source of the petrification beam in South America as they flee from Stanley's ship. 

Senku and company must flee from Stanley's ship, but they have to make stops to refuel.

After falling for a decoy, Stanley's team finally catches up to the crew, who must now outwit them while racing through the desert.

The team is going to need a weapon for when Stanley inevitably catches up to them.

Senku and his team have lost Stanley for now, but they aren't out of -- or rather, in -- the woods just yet.

The team discovers a giant pile of petrification devices. They take them apart to see what makes them tick.

The team begins making, digging for, and polishing diamonds to replace the burnt-out ones inside the devices.

Suika is in charge of making sure Senku's plan works, but her kindness becomes an obstacle.

With the revival team captured, it's up to Luna and Chelsea to revive everyone when the time comes.

With the petrification beam approaching, who will get their hands on the revival fluid?

Suika gathers the team's statues, sets up camp and gets to work doing science.

With Senku back, it's only a matter of time before the rest of the Kingdom of Science is revived.

Senku and Dr. Xeno team up to gather the materials needed to make a rocket engine.

The crew arrives in Spain, where they collect fluorite, olive oil and some treats.

The New Perseus sets out to India to recruit mathematicians for the space program.

The computer that the team is building is a series of toroidal tubes. Senku explains.

The team gets to work wiring up several megabits' worth of memory donuts for their computer.

The team will need a stupidly insane amount of electricity to turn their bauxite into an aluminum rocket body.

With the computer completed, the team will need a user interface: a TV.

The Kingdom of Science's rocket launches are mired by a string of rapid unscheduled disassemblies.

The team is too small to build a round-trip rocket. They'll need to enlist help from around the world.
