"Velikan is a shadow of a shadow. Tales of his exploits are written off as fairytales at best and gross exaggerations at worst. Those who know him never speak ill of him. Whether it’s due to fear or respect, no one knows."
Next to nothing is known about Velikan, save for his mysterious identity and reputation as a highly trained assassin. It can be noted that by looking at his Woodman outfit in Call of Duty: Modern Warfare, he appears to have dark colored eyes, presumably brown. At some point, he joined Shadow Company as a mercenary.
Velikan means "Giant" in Russian and other Slavic languages.
In Serbo-Croatian, Velikan means "Great, Renowned Man" which may be a nod to the "tales of his exploits."
Velikan's blood type is AB+.
Velikan was originally shown with a different mask design in his bio picture; instead of his standard Oni decal, the picture depicted his mask with two horizontal jagged lines resembling a mouth. This was fixed in the Season Six update.
The preview image for Velikan's "Take A Bow" finishing move also shows Velikan with his original mask design.
Unlike other operators, Velikan does not speak, even during callouts.
The only instance of his voice being heard is during a Finishing Move, where his default quip is him menacingly laughing in a muffled tone.
