Iron Man, Captain America, Thor, Hulk, Black Widow, and Hawkeye are back with another heart-racing episode in Marvel's Avengers Assemble! In season 3 episode 21, entitled "Building the Perfect Weapon," the team finds themselves in a race against time as they attempt to thwart the menacing attacks of the ruthless villain Ultimo.

In this episode, we see the Avengers trying to stop Ultimo, a powerful and nearly indestructible robot, from wreaking havoc on Earth. The team discovers that Ultimo has been created by the evil A.I.M. organization, which has been building the robot in secret.

The Avengers launch a full-scale assault on A.I.M.'s stronghold, confronting a host of highly trained soldiers and battling their way to the heart of the facility. Once there, they find the massive robot and engage it in a fierce battle. However, they are quickly outmatched by Ultimo's sheer strength and weaponry.

Unbeknownst to the Avengers, A.I.M. has been working on another top-secret project: a device capable of controlling Ultimo's actions. Using this weapon, A.I.M. takes control of Ultimo and turns it against the Avengers. Thus, the Avengers find themselves fighting not only Ultimo but also their own teammate, the mind-controlled Hawkeye.

As the battle rages on, the Avengers realize that they must find a way to break the mind control allowing A.I.M. to manipulate Ultimo. The stakes are high, as the robot's destructive power could ultimately prove catastrophic for all of humanity.

In the midst of the chaos, Iron Man devises a daring plan - he proposes that they build their own weapon, capable of controlling Ultimo from the outside. With the help of his teammates, Iron Man sets to work, and the Avengers begin a desperate race against time to complete their device before it's too late.

The tension builds as they work feverishly, with the clock ticking down and the fate of the world hanging in the balance. But despite the odds stacked against them, the Avengers manage to pull off their impossible feat, constructing their own weapon and using it to take control of Ultimo.

In the explosive conclusion to this thrilling episode, the Avengers unleash their weapon on A.I.M.'s forces, turning Ultimo against its own creators and putting an end to their diabolical scheme. But the battle takes a toll on the team, leaving them weary and shaken as they regroup to face their next challenge.
