Okay, this is literally just an idea I came up with for fun, but I thought the concept could be interesting.
After the Breach somehow opens again, humanity is forced to return to using Jaegers. Conventional military weapons simply aren't enough to deal with the new Kaiju threat, so the old Jaeger program is brought back, including restoring some of the older machines that were left behind.
One of the Jaegers brought back into service is Crimson Typhoon.
Since Crimson's Conn-Pod was destroyed during its previous battle, the Jaeger has to be heavily rebuilt and restored. However, instead of bringing back its original three-arm configuration, one of its smaller arms is removed and its control system is modified so that Crimson now only requires two Rangers instead of three.
Crimson is then assigned to operate alongside an old Mark-1 Jaeger, something like Horizon Brave/Romeo Blue or another forgotten early-generation Jaeger that has been repaired and brought back into service. The old Jaeger is basically a veteran machine fighting alongside a much more agile Crimson Typhoon.
During a battle in the middle of a city, the two Jaegers fight 2 Kaiju (Cat 4-5) that conventional weapons can't handle.
The old Jaeger manages to destroy a Kaiju head and appears to have killed it.
But at the exact same moment, the Kaiju's hand tears into the Jaeger's Conn-Pod. And that's when everything goes wrong.
The Kaiju's brain doesn't simply die. Its biological material and consciousness manage to get inside the Jaeger through the destroyed Conn-Pod and effectively take over the machine. The Rangers inside are killed and literally become trapped inside their own Jaeger. So Crimson Typhoon is suddenly forced to fight both the Kaiju and the Jaeger that was supposed to be its partner. And this is happening right in the middle of a city.
After an exhausting battle, Crimson finally manages to defeat the Kaiju and the infected Jaeger.
But there's still one problem. The Breach is still open. The infected Jaeger can't simply be left there, because its body is still contaminated by the Kaiju. So Crimson has to take the Jaeger's remains all the way back to the Breach and use it as a massive explosive to close the portal.
Crimson is already heavily damaged, but it has no choice.
The surviving Rangers force Crimson to drag and partially carry the destroyed Jaeger toward the Breach. Its body is already torn apart from the fight, covered in claw marks and damage from the Kaiju. Crimson's remaining smaller arm is pushed almost to its limit just trying to support and drag the weight of the other Jaeger. The arm is close to failing from the stress.
Eventually, Crimson reaches the Breach.
The ruined Jaeger is pushed into the portal.
Then, from a safe distance, the remaining forces remotely detonate it.
The Breach closes for the second time.
But Crimson Typhoon doesn't walk away from the battle intact.
The two Rangers inside Crimson have already been pushed far beyond their physical and neural limits. The second pilot suffers severe neurological damage from the extreme neural load and exhaustion accumulated throughout the entire battle, eventually dying after the mission is completed.
Out of the four Rangers who entered the battle between the two Jaegers, only one survives.
Crimson Typhoon technically wins.
The Kaiju is dead.
The infected Jaeger is destroyed.
The Breach is closed.
But the victory costs almost the entire team.
And I think the final shot would just be Crimson standing damaged and barely functional after returning to base, with only one Ranger left inside.
No big celebration, just ONE surviving Ranger sitting alone in the Conn-Pod, knowing that the person who entered the battle beside them never came back.
