Store-O
Description
Store-O is the 4th of the robot helpers created by The Inventor. Store-O is unlocked by having spent 75,000
Time Shards on inventions in total on the current prestige run. By default, he has one available slot to store an item similar to the Crate and Cage and 2 more slots can be unlocked by purchasing the individual upgrades from The Hacker for 100 
Energy Cubes and 500 
Gems, respectively. Store-O is able to store items that both the Crate and Cage are able to store, aka both Items and Minions. Is able to be fed to the Devourer but only when he contains no items, similar to the Cage and Crate.
Store-O also has the quirk that he acts like a pseudo-time capsule; when you use the Time Machine, he and any items he contains are unaffected by the prestige reset and can be collected from the Inventor with the items stored in him still present. This allows for a lot strategy involving bringing back stations to access Minions you would normally not have access to until later in the game. However you will want to take note that these stations will not be able to be upgraded until you re-unlock the station nor be merged into Legendary Minions until the corresponding Feat is completed, with the exception of the Robo Chicken as it has no unlock requirements besides having purchased him from the Surgeon.
