Da Zog... Wot in da name of Gork an Mork ar you'z talkin 'bout (In all honesty, Orks love fighting, killing, looting, and just generally WAAAGHin it up somewhere. An Ork can love Choppin some git to pieces. But there's a difference between being able to love something, and being able to love someone. Orkz have no concept of loving anybody. It's just not a concept in their minds. The closest thing they can get to love is having a particular enemy or a particular person that they love to fight. Example Ghazghkull and Yarrick, Commisar Yarrick has proven himself to be able to "fight proppa for a 'ummie". To be fair decapitating a Warboss with his own Power Klaw and the using said Klaw as your new hand is pretty damn Orky. So Ghazzy loves to fight Yarrick, because he knows he's put up a good fight. To the point that when Ghazghkull captured Yarrick during which ever battle for Armageddon it was he let the Commissar go. It's more respect for ones orkyness and ability to fight then love. To quote Ghazghkull himself: "Humies is all weak scum that deserve ta get stomped. 'Cept for One-Eye Yarrick. He knows how ter fight." "Friendly" Enemies is probably the closest thing to endearing an Ork can get, and it's usually only a one sided relationship considering everyone's reactions to Orks. The sheer concept of love is not only alien to them but completely unnecessary to even think about due to them being asexual and their reproductive cycle requiring no partner. So recognition of fighting prowess from an Ork is the only form of flattery one could get from them, because it's the only thing they care about, and it's the only thing that matters to them. So for your Warboss and Tau whatever, it's not going to be love allying them together. It's going to be more of a begrudging "only I can defeat you" situation. That's the closest thing to a "marriage" an Ork can get with someone is stating that if anyone is going to kill them, they will, on their terms. So yeah Orks can feel love, just not in the same way we would see it. Unless you're Rook Dook Even then I don't think it's love)
Love conquers all. If the warboss and commander can make it work, they will find a way I think you should go for it, and even more so because Valentine's is right around the corner p.s. It was just impossible find a Valentine/love-themed picture with an ork in it. This was as close as I got
My ork Bugkrusha sure loves his choppa and his shoota. An' smashin' finks an' stuff (which iz mostly 'oomies an' simlar gits.) Dem 'oomies make funny noises when dey fall ova.
The ork likes her dakka and the tau wants too have an ork join the greater good and alittle etheral magic is involved
Gork will make you fall for him and then break your heart, while Mork will break your heart after you fall for him.
