As the title suggests, I'd love to hear some of the oddest OC's you've encountered or made in any format: forums, tabletop, etc

I'll begin with one I've encountered and one that I made.

One was a bit of a head-scratcher for me...and proved why I have a hard time playing pregenerated characters ideas without A LOT of detail being explained first. Person had a whooooooole universe plotted out and our characters were on opposite sides of a war. 

- Got into a space fight and both ships crashed to an alien planet. OP's character's ship protecting mine from burning up in atmospheric entry

- Person's character crash lands without taking any injury. When asked why, it was because Character is genetically modified.

- Character hikes 5 miles in unfamiliar territory in about an hour, taking time to observe dangerous fauna along the way.

- Character understands enough of MC's language to have basic interactions. Then proceeds to build a translator using MC's ship computer so now they can communicate. When questioned why, it's because Character is a military engineer

- Has our characters trek back to Character's campsite, cautioning MC to stay close and hide, needing to protect them because MC doesn't have the skills and experience necessary to survive an unknown land. When asked why, it's because Character was genetically engineered to survive on harsh worlds.

- Character has a very rare sword that is more special than other soldiers' swords.

- When attacked by a large creature native to the planet, Character kills it with a very precise strike with the special sword to sever the spinal column in it's back. When asked about how Character knew to make that precise strike on a creature never seen before, apparently Character figure that out on the hike over here.

I felt like I was just writing alongside someone's superhero fantasy. When asked what MC's purpose was for being there, what could MC do that Character couldn't, I got the response of "well...you said you were going to have them collect plants, right?" I asked for more specifics story-wise of my MC was supposed to be there and the person never answered, so I just left.

Oh...and all of what I described happened in the space of less than a day.

For MY cringey character:
Whe. I was much younger, I was a huge Jurassoc Park fan. I ran a message board about it and everything, and it had a roleplay section. I made a roleplay character whose parents crash-landed on one of the islands when she was a baby. She was then orphaned after her parents were killed by velociraptors and she was "adopted" by the raptors and grew up to be part of the pack. She could talk to all the dinosaurs on the island and could run as fast as the raptors and InGen wanted to capture her to find out why she survived among the dinosaurs for so long....

Oh my gosh.... It was so awful....
