Operation: Unknown is an upcoming RPA Mission taking place from April 9th, 2017 to April 23rd, 2017. It was going to start on April 2nd, 2017 and end on April 16th, 2017 but due to the agency needing more time to get ready, it was delayed. It is currently unknown whether or not the Super Hero Agency will make an appearance.
After Fire Spider killed Agent Unknown at the end of Operation: Waddle On, the RPA has been forced to move their HQ to the new Club Penguin Island without him. However Agent Bon Chaos has created a new potion that might be able to return Unknown to life. However the RPA will have to go through many dangerous tasks in order to revive him and it's so dangerous that if even one small mistake is made, all of them could be facing death immediately.
- This is the first mission to be named after an agent.
- If it were not for the cancellation of Operation: Nintendo, this would have been the second.
