My exp is very badAs of my last knowledge update in January 2022, I don't have specific information about an agent named "ISO" in League of Legends or other popular games. It's possible that the agent or character you're referring to is from a game released or popularized after my last update.
If "ISO" is an agent in a game released or updated after January 2022, I recommend checking the official website of the game or its community forums for the latest and most accurate information. Game developers often release patch notes and updates that provide details about new agents, characters, or champions, along with their abilities and roles in the game. Additionally, player communities are a valuable source of information and discussions about new content.
If you have additional details or if "ISO" is from a specific game, please provide more information so I can better assist you.
