(｀_´)ゞ note The signature emoticon Comcept uses depicting Beck saluting.
Arm Cannon: Being an expy of Mega Man, this signature weapon is a must-have.
The Assimilator: Beck's primary power is to absorb Xelsnote Nano Machines that all robots in the game are made out of. from other robots and using those acquired Xels to transform his body thus gaining their powers, abilities, skills, traits and characteristics and use those to his own advantage.
One method for him of accomplishing this is by "absorb dashing"note As seen in this video. towards a weakened or stunned robot.
Blade Below the Shoulder: Some of the concept art show him with wrist mounted blades along with a pointy armor to go along with it.
Cool Helmet: He'll acquire different looking helmets (along with the rest of himself) as he gets more transformations.
Cool Mask / One-Way Visor: His visor is called a "C. Visor" based on one of his official artworks. We see him using it in some of his concept arts so it might probably have some function and not just to only look cool. Plus it also changes with him so we'll get to see him wearing an assortment of cool masks and visors as he acquires more transformations.
Do-Anything Robot: Given that he can potentially reconfigure into practically anything, it's most likely that he can become this.
Non-Action Guy: Unlike his predecessors, he is not an effective fighter in Battle Colosseum battles, due to his human emotions being wired to his abilities, thus tending to go haywire. By the time the other robots went berzerk, he needed the encouragement of Dr. White to boost his self confidence and resolve to save the day.
Power Copying: Even more extensive than the original's Mega Manning powers, his entire body changes and copies the enemy robot's features, traits and powers though he doesn't look like a clone and more like a modified version of his original design.
Punny Name: In conjunction to Call. Making "Beck and Call" similar to Mega Man's "Rock and Roll".
Retractable Weapon: Aside from reconfiguring his entire body, he can also reconfigure his arms and hands into various weapons and tools.
Ridiculously Human Robot: Says to possess the unique trait of being more human than any robot created before. Unfortunately, this leads to his intrusive emotions and lack of courage impairing his effectiveness as a hero.
Telescoping Robot: He seems to be able to conjure and/or store additional parts, attachments, add-ons, components and even an entirely different body when he transforms. How he is able to store all those things when he returns to his default form hasn't been revealed yet and is still a mystery.
Transforming Mecha: He is capable of reconfiguring his body to form anything from a bulldozer/loader/tank form to a gigantic rocket propelled hammer.
Motif: Says to made to resemble a boxer or a wrestler. He even was planned to be able to deploy a wrestling ring (the corner posts and ropes at least) on his back and use the ropes as momentum for a charging attack.
His redesign on the other hand is of a lighter. Specifically the part where the flames are ignited.
The Faceless: In the concept sketches, there is a drawing of him with a more humanoid head, possibly hinting that what we are seeing is merely a helmet and not his actual face.
Head Swap: If you examine his character design closely, you'll see that he has the same body as Beck but with a red paint job, subtle changes here and there and additional accessories.
Highly-Visible Ninja: He "wears" a helmet with a a pair of blade-like horns jutting out of it with a large beak-like collar guard. Not to mention that he lugs around those pair of half scissor styled blades that's almost as tall as him.
Shear Menace: Though he doesn't use actual scissors, his swords are distinctly scissor-themed, and artwork depicts him crossing them a few times to resemble scissors.
Sibling Yin-Yang: He is designed by Comcept to be Beck's "brother" character and it shows. Beck is blue. 7 is red. Beck's main weapon is a ranged weapon. 7's main weapon are melee weapons. Beck looks enthusiastic and determined. 7's grim and serious.
Sticks to the Back: According to Comcept, when not in use, he puts his swords on his back, placing them to make it look "almost like butterfly wings". So far we haven't seen anything behind his back in the concept sketches that reveals what could hold said weapons in place nor have they revealed any information that would explain how it would it hold them in place there. Probably magnets or something.
Throwing Your Sword Always Works: One of his concept sketches shows him jumping high into the air and throwing one of his swords at a distance to the ground, presumably going to be one of his attack moves in his boss fight.
Cool Shades: As if his his eyes aren't obscured enough, he's also wearing shades under his hatnote As evident on this image◊, revealing that the blackness isn't a shadow due its shine. or probably those are his eyes seeing as he is a robot and all.
Cold Sniper: The quiet, camouflaged-from-the-shadows type with a sniper rifle arm.
Cyber Cyclops: His only visible or true eye is located on top of the front edge of his radar/sombrero hat.
