Half-Celestial and Half-Fiend

[DireSickFish]

So is Half-dragon the only template we have to work with for the half-x creatures? Going to include a half celestial in my plot, wondering how much ill have to homebrew if they fight it.

[Demonic Spoon]

a Cambion (MM) is effectively half-fiend; you could probably homebrew something based on that.

A Cambion is a Half-Fiend, and an Empyrean can be a Half-Celestial, though it's more like a titan.
