Apex Legends players often complain that they don't have enough content in the game, especially new Legends. Since the game's release, only Octane and Wattson have been added as new playable characters.
Crypto seems to be the next to join Kings' Canyon, but we may already know who will follow. This new character would be a woman named Rosie. That1MiningGuy — a famous leaker and dataminer — even shared his theory that Wattson was tutored by this Rosie when she was growing up in King's Canyon.
If true, it would help to develop characters' lore and create real links between them. However, we must remain cautious as these are only rumors, and Respawn has yet to confirm anything.
