9. Being Used As A Human Cloaking Device
Ricks are often rather cavalier about how they treat their Mortys, but the Rick working for Evil Morty in Close Rick-counters of the Rick Kind takes the disregard for Morty's human rights (and dignity) to a whole new level.
In an effort to hide himself away and prevent anyone from finding his location (particularly other Ricks), this Rick built a high-tech dome around his lab and covered it entirely in hundreds of naked screaming Mortys. If you're a Rick, keeping a Morty by your side at all times is a great way to blend in and remain unnoticed, but according to our Rick, this works even better if the Morty is in constant pain. Because of course it does.
Morty is horrified to see his fellow Mortys being poked and prodded by automated torture devices simply so the Rick inside the dome can stay hidden.
Rick, on the other hand, is unimpressed by the inefficient design, stating that you could achieve the same result with just five Mortys and a jumper cable. How does he know this? Apparently he's experimented with a few concepts... purely theoretically, obviously.
