What are your ideas for Variants?

If you were to create a variant, what would you make?

My Idea:

Fulgurbug Rajang: A Rajang that never ate a Kirin horn, and instead, got into a symbiotic relationship with Fulgurbugs after killing their Zinogre, Rajang now uses them instead. Instead of mouth blasts, his electric attacks are based around his physicality and also gives him some AOE attacks like the spinning balls Zinogre uses.
