Inque & Blight vs Clayface & Poison Ivy

Easily the Beyond duo, Inque is more impressive than CF, she's shown to be faster, smarter (judging by her career as saboteur) and just more adaptive with her powers, and even if she went down somehow, neither CF or PI have anything that can put down Blight, he'll just disintegrate any plants and simply glass CF or burn and solidify him beyond his regenerating abilities.

People forget that the beyond villains were all unstable. Bat classics can hold out. Blight dies when he uses his power
