Megatron’s 46-Year Wait: Strongest Transformer of All Time Finally Debuts as Megatronus Rex

The Decepticons return to battle

The Energon Universe launched in 2023 with Void Rivals No. 1, where Image Comics and Skybound revealed that the Transformers were part of the project. The conflict between the Autobots and Decepticons went on to become a major storyline in Transformers.

Megatron’s powerful new form

The battle’s consequences reached both sides. Optimus gave up the title of Prime to Elita One, while Megatron was sealed in a crystallized cocoon until he submitted to Megatronus. Megatron has now returned stronger and more determined, while Optimus has yet to adapt to his reduced power.

At the 2026 New York Comic-Con, Megatron’s return as Megatronus Rex was announced. In Transformers No. 39, the new form proves to be more than a heavily armed upgrade: he can become a tank large enough to destroy the mountain that shelters the Autobots.

Megatronus Rex then reveals another transformation: a railgun so large that Devastator can hold it. The display establishes him as the biggest weapon in the conflict, leaving the Autobots facing a grave threat.

Possible help for the Autobots

Elita Prime came to understand why Optimus chose to remain on Earth. In Transformers No. 38, she agreed with Jazz’s proposal to send help and Energon to aid the former Autobots. If support arrives in time, it could help them escape, though it may not be enough to win.

Soundwave may also be a potential source of help. His rivals showed him mercy after capturing him, and Firecracker, a former Decepticon, told him he would eventually understand why he switched sides.

Soundwave’s possible change

Megatronus Rex struck Soundwave hard enough to send him flying as Soundwave moved to attack Optimus. After serving Megatron for eons, the attack could prompt Soundwave to reconsider his leader, who has been described as selfish and willing to endanger his own side to survive.

Optimus, by contrast, has sacrificed parts of himself to protect the Autobots. Soundwave’s possible betrayal could become a major turn in the series, but his survival is in doubt if he helps his enemies.
