Respawn usually follows the same formula leading up to the start of a new season in Apex Legends. It starts with an animated short, then a so-called launch trailer teases what's to come before a gameplay trailer gives a quick overview of the upcoming inclusions and changes. The fourth video is usually a character trailer detailing the new contestant's abilities. Season 17's version mostly follows procedure.
I say mostly, because the narrator in Ballistic's character trailer is...less formal than we're used to, as his former butler is the one confirming that the older gentleman can carry three guns, overheat enemy weapons and finally: give his teammates unlimited ammo and faster reloads by activating his ultimate.
