Honestly? Goliath and Beast. Gargoyles is my favorite show of all time, and I liked how the mini story both captured each character. For example thier meeting starts off like this:
Spoilers
Goliath: “I hear you were prince!”
Beast: “I still AM a prince. Just not much of one.”
Goliath: “Ah, it’s a burden to lead, though. To care for your clan.”
Beast: “My clan?”
Goliath: “Your family. The people who rely on you. The people who fill your castle with life.”
This is exactly how Goliath would talk when meeting a fellow magical being. If the two characters ever met up in alternate universe, I can see Goliath reaching out to Beast, the same way Belle did. And I also can see Beast accepting Goliath as both are outcasts to humans.
