Very tall, obviously robotic, somewhat skeletal in appearance. He was designed to be intimidating. Silhouette is broad (especially thanks to his shoulder plates) with a bulky chestplate and inhumanly long, thin limbs. Lower torso is a narrow, flexible spine with multiple pistons supporting the weight of his upper body.

Body language generally either very aggressive and direct or very apathetic and standoffish, depending on his mood. His posture is somewhat poor, with a tendency to slouch. When fighting or hunting down a target, his movements are extremely predatory and deliberate. When sneaking or stalking, especially when moving in a crouch or climbing around on walls or ceilings, he has been described as skittering, somewhat resembling a very large spider.

Eyes glow yellow, he does not have eyelids and so never blinks. The intensity of the light of his optics may change— for example it seems to flash brighter with strong emotions, such as when he's feeling especially murderous, or dim and flicker off briefly when in extreme pain.

Important to note is that he does not actually have a mouth, so his jaw and lips don't move when he speaks.

The only clothing he wears is a red cowl and bandana, and a red loincloth (presumably due to some lingering sense of shame from when he was human, because he sure has nothing to cover up down there).

For a visual example you can check out his intro in the season trailer here.

Voice is extremely deep, with obvious distortion/reverb. Clearly sounds robotic.

Has a tendency to drawl, speaking very slowly and drawing out his words. Sometimes sounds breathy even though he doesn't actually breathe. Tone is typically apathetic, faintly amused, mocking or sarcastic, and often comes across as strangely flirtatious. In a poor mood his tone becomes much harsher, generally extremely abrupt, aggressive, direct and unapologetically ill-mannered.

He also has a habit of growling, snarling or even making weird breathy purring kind of noises because he's creepy like that.

Painfully edgy voice examples can be found here and some of my favourite stupid lines (and examples of his creepy growl-purr) here from 0:12 to 0:58. Bonus because lol.

As far as movement goes, his robotic parts make surprisingly little noise. There may be some faint whirring of gears and pistons, especially audible to those with sensitive hearing. If he's trying to be stealthy, his footsteps are also extremely quiet, though not quite silent.

Metal, machine oil, and gunsmoke. Probably also blood, but not his (he has none).

In Noctium he's currently living in the sewers so... yeah. I'm sorry for him.

A large, foldable scythe with an extendable, whip-like blade. This weapon was developed specifically for Revenant by Hammond Robotics and glows with the same strange red-orange static as his silencer and totem.

Built in to the back of his shell, the jump kit is a small, low-powered jetpack that allows for survivabilty on potentially fatal descents by decelerating to prevent fall damage. It does NOT allow for flight, gliding, or increased jump height, as it cannot produce the required lift.

A small device which is stored inside his left forearm and fired by extending two fingers backwards to use them like a slingshot (because he's creepy). When launched at a target it leaves behind a static-like red cloud at the point of impact which blocks other people's "abilities" if it hits them (or if they come into contact with it while it's on the field)— in the Apex universe these are all in some way technology-based rather than being supernatural, so essentially it uses some sort of electrical impulse to prevent technology from functioning for a brief period of time.

A strange piece of technology which allows him to shift into an semi-corporeal shadow form (pictured). It takes the form of a small metal skull (as seen on the side of the device) until it is deployed. It has not been explained how exactly it works, as according to the devs this is a spoiler tied to a future character.

The shadow form protects him from death for a short time— when "killed" as a shadow, his body dissolves into smoke and he is returned to the location of his totem in his normal form. This does not prevent the pain from whatever killed him as a shadow and as a result it may affect the function of his physical form. If not killed in shadow form, it eventually wears off on its own, without the recall to the totem. Destroying the totem also immediately throws him out of shadow form.

A placed totem can be used by anyone to become a shadow, it is not limited to Revenant himself. They only have to touch it.

Note: Outside of gameplay he has been shown entering his shadow form without first deploying the totem and apparently choosing where he wants to reform when destroyed. It may be that the totem is only required to avoid breaking the game to be deployed on the field to allow his squadmates to use it, while Revenant can shift as long as he has the skull device in his possession.

He was once a professional hitman and considered to be the best the Syndicate had ever had. Needless to say, he's very good at killing. Highly proficient in both hand-to-hand combat and a wide variety of firearms.

As a robot designed to kill, Revenant is obviously a good deal stronger than your average human. [ADD EXAMPLES]

However, he is not supernaturally strong and certainly not infallible. It's canon that he's died hundreds or even thousands of times, after all.

Capable of scaling sheer verticle surfaces with ease (e.g. climbing up the outside of a skyscraper) and even scuttling around on ceilings like a huge metal spider. Makes very little noise in motion, with very quiet (but not quite silent) footsteps and next to no sound from his mechanical parts.

He's able to "dislocate" his shoulders and hips which gives him a wider range of motion and makes his limbs even longer. One effect of this is that his movement speed isn't compromised in awkward positions, for example when crouching. His fingers also extend, and he can flatten them together and use them as a weapon to stab people with. It's creepy. He's creepy.

At one point he hacked the supposedly "unhackable" drone of the one character whose entire thing is being an extremely skilled hacker and encryption expert, and used it to spy on the other Legends. It's unclear whether this was a skill that Revenant possessed as a human or a side effect of the fact that he's essentially a computer himself now.

In the event of "death" (a system failure or the destruction of his synthetic shell), his mind is automatically copied and reuploaded into a new body. He has a lot of spare bodies... whole warehouses full of them.

Note: In Noctium, unfortunately (or fortunately?) for him, these replacement shells won't be accessible, so this ability has been nerfed.
