Transformers ONE (2024 Movie)

I used my OC here, so don't think Sybil is a real character:

Sybil Nova, Sentinel's adventurous sister, joins Elita, Orion and D-16. Despite Sentinel's disapproval, Sybil finds comfort and excitement in his company. During a daring exploration, they narrowly escape Darkwing and learn about the legendary Matrix.

Orion and D-16 participate in the Iacon 5000 race, despite their lack of experience. Although they lose, their determination impresses Sentinel, who offers them a reward. However, Darkwing's betrayal takes them to level fifty of the building.

With the help of B-127, they discover a secret message from Alpha Trion. They escape from level fifty and board a train, but their journey is cut short by a tragic accident.

Guided by the coordinates of Alpha Trion, they arrive to witness the tragic fate of the Primes. Sybil is devastated to discover the truth and D-16's anger grows. Starscream kidnaps the group and is nearly killed by D-16.

Sybil regains consciousness and finds Sentinel Prime, now a powerful tyrant. She tries to stop him, but her pleas are ignored. Orion and Elita arrive just in time to witness D-16's descent into madness.

D-16 attacks Sentinel and kills him. Sybil is devastated and Orion, now Optimus Prime, fights Megatron. Sybil confesses her feelings for Optimus and the Autobots decide to remain on Iacon while Megatron and the Decepticons leave. (I just said almost the entire movie 😂)
