Autobot leader Optimus Prime brings back and wields his mighty Cybertronian sword in the promotional art of Transformers: The Last Knight, and given the title of the film, it's a fitting image.

And while new and returning Autobots and Decepticons may primarily use ranged weapons, the leader of the Decepticons will match Optimus in old school medieval close-range combat. At least, that's what we presume will happen from the brand new first-look image of Megatron in his updated robot mode that director Michael Bay just shared.

From new Megatron's shoulder and waist skirt armor designs to the closing protective helm, wrist-mounted gun (which doubles as a shield) and a sword with an axe-like tip - Bay isn't messing around in living up to themes and iconography implied by Transformer 5's "The Last Knight" subtitle.

Of course, our immediate reaction to the close-up of the 'closed' helm design is to compare it to Ultron's from Avengers: Age of Ultron. Same color scheme and red lighting of course, and when you think about it, Megatron evolves in his design from movie to movie like Ultron upgrades himself with new tech and metal.

It's unclear what vehicular or alt modes Megatron may have in Transformers 5 but to compare to some his previous live-action movie designs, here are some images:
