One heartbroken fan of the Mars Opportunity Rover has started up a petition to get the recently deceased robot added to the Mortal Kombat 11 roster.

Stars from different franchises popping up in rival games is becoming more and more common nowadays. The Walking Dead's Negan is going to be a playable character in Tekken 7, Cloud joined the ever-growing cast of Super Smash Bros., and both Darth Vader and Yoda were a part of the roster for Soul Calibur IV, depending on which platform you were playing it on.

It seems that fans are now getting a little too hungry for character crossovers, especially when it comes to the fighting genre. Mortal Kombat 11 will be released later this year and since the roster is yet to be finalized, fans are calling for all sorts of additions to be made. Doomguy's name has been thrown around a fair bit, and it took Mortal Kombat's developers actively telling players, "No," to put an end to the Shaggy from Scooby Doo rumors.

Now that players' dreams of using Shaggy to kick the crap out of Scorpion have been officially squashed, one fan has moved on to another request. Ruel Huerta has taken to change.org and started a petition for the Mars Opportunity Rover to be immortalized as a playable character in Mortal Kombat 11. That's right, the robot that has been exploring the red planet for the past 15 years, whose battery ran out for the final time last week.

Huerta has written on the petition that he wants the Rover to be remembered for all of its hard work, signing off with, "I'm shaking and crying rn." After hearing the brave robot's heartbreaking final words, Ruel, I think we all were. At the time of typing this, the petition has broken the 900 signature mark. While that has far surpassed the 200 goal Huerta set for himself, it'll need a lot more than that to garner the attention of NetherRealm Studios.

As entertaining as the Mars Rover being added to Mortal Kombat 11 might be, we are of the opinion that the novelty would quickly wear off. The MK series is a pretty serious one, and we're not sure how a NASA robot's move set would look in-game. If you want to use a robot to battle various other characters, we'd recommend sticking with R.O.B. in Super Smash Bros.
