Mortco is the popular ship name for Marco x Morty from Rick and Morty. Both of them are teenagers, go on interdimensional adventures with a crazy person and they wear a primary color, so it is no suprise that this is a ship.

Probability of CanonEdit

Considering the fact that both characters are from different shows and the fact that Adam McArthur has stated that, due to copyright Star vs. the Forces of Evil will not have a crossover with other shows, and that Morty is from a adult show while Marco is from a kids show the chances of it becoming canon is 0%.
