Okay, a few things.
One, I thought the title to this topic was referencing ships that transport crack. Honestly, I did. Someone help me.
Two, romance isn't canon in the MU. (JK, I know everybody knows this.)
Three, if I were to ship anybody, it would be Macku X Hewkii, Jaller X Hahli... and Tahu X Gali? //Shrugs//
But guys, this raises an interesting question. If romance were to exist in the MU, and Hewkii and Macku still had feelings for each other after the former became a Toa... would that mean they carried an interspecies relationship?
I think you mean Vakama X Breez.
