zepon lizard clan chief and yuber

[conan]

i was playin suiko III again and realized yuber had a grudge 2 settle with zepon from long ago. does any1 know what that beef was, and if yuber was involved in the 1st war? its possible that geddoe neva mentioned it cuz he keeps 2 himself so often, or maybe becuz yuber changed his appearance. and if yuber changed his appearance, maybe its cuz he wants 2 keep a lower profile, so he wouldnt mention geddoe. maybe zepon had a diffrent battle with yuber and managed 2 repel him, since he seemed like he had some kinda spiritual connection. any1 have any ideas on this?
