"I prefer my past to be multiple choice."
Name: Ivan Rosing is what people call him.
Real Name: Valinor Dracarys Lain
While being a certified member of supernatural department of protection KNYFE, he works as a freelance detective/monster slayer for fun. He sees the world as a boring playground that needs a bit of spicing up, so he goes on any adventure he can with any alleged friends.
He's a metahuman, and a very gifted one. His superpower, so to speak, is extreme intelligence and ability to retain information. Most of the equipment on him he built himself. He also owns very strong lightweight gloves, cut at the fingers and able to exert electric energy. He can build and manipulate tech very effectively, as demonstrated, and has a red data-handling eyepiece that can serve for purposes similar to Batman's detective mode. Think x-ray vision and forensic analysis.
He is extremely agile, able to swing and jump to incredible heights and land without harming himself. He is not the fastest runner, but his acrobatic prowess makes him a nightmare in the air and his tactical thinking gives him the advantage on most fields of battle.
When he's out, he's got a layer of clothing below his coat preventing his body from tearing itself apart when grappling and he's got a little belt equipped beyond his jacket that has all sorts of KNYFE gadgets:
-Mini Helicopter Drones
-Grappling Claw Launcher
On his left arm is a gauntlet with a screen and cryptographic sequencer capable of hacking into different systems, video calling associates and remotely destroying, taking over or changing the functionality of nearly any device. Think Watch Dogs.
On his right arm is another gauntlet with a wrist mounted gun, capable of shooting regular bullets or exerting and directing electric energy. This gauntlet can also eject a short blade that he can either throw or keep in his hand for close combat.
He is an observer, and catches many things at once with his eye and deduces many things instantly. His skills are equivalent to Sherlock Holmes', and he can discover all a person has done in the previous week in a matter of seconds.
His rarely used, heavy combat strategy is the HORUS suit (spoiler below).
The reasons for him to have obtained his powers and his certifications at such a young age and anything thereof are very well kept, as secrets, because Ivan is quite reserved about his past.
He constantly gets on people's nerves, because seeing as he's really, really smart, he can be very arrogantly annoying. He cracks jokes whenever he can when he's supposed to be doing very serious work, and will often look to his laziest, most drastic and action-scene options when on missions.
He's smug and stubborn, but really nice to those he trusts. If he becomes too attached, however, he may cause trouble. Or at least, more than usual. His regular behaviour shows he's calm, controlled and focused.
