Litwick regional variation for the Kroel Region, with a more Japanese inspiration:
-Kroelian LITWICK (Ghost/Rock) is based on Warosoku candles
-Kroelian LAMPENT (Ghost/Rock) is based on a TMrM, a Japanese garden lantern
-Regional evolution ROLINFERNO (Ghost/Rock) is based on the WanykdM (Yokai)
-MEGA ROLINFERNO (Ghost/Fire) is based on the Katawaguruma (Yokai)
They have an ability called "Fiery Spirit" Which boost the power of Fire-Type moves as well as preventing Freezing, the Mega evolution has the ability "Flame body"

Again it is just WIP but people really liked this one on twitter, hope you like it as well
