Final answer:
Omen from Valorant has an ultimate ability called 'From the Shadows' allowing him to teleport and briefly appear as a shade, which can be killed by enemies to cancel the teleport.
Step-by-step explanation:
The shade form referred to in the student's question relates to Omen, a character from the popular video game Valorant developed by Riot Games. When Omen uses his ultimate ability, From the Shadows (X), he can teleport across the map to any location. While selecting the teleport destination, Omen appears as a shade that can be seen by enemies and can be destroyed before he finishes the teleport. If the shade is killed, Omen will return to his original location but not die, and the ultimate ability will be put on a short cooldown. This ability is strategic for repositioning and gathering intelligence without putting Omen in immediate risk.
