Fire:
Series 1: Sunburn. I always liked his playstyle and powers. I like his design, art, figure! He's just always appealed too me.
Series 2: Flameslinger. His Wow-Pow looks really good and I have always liked him. His new design looks pretty cool also.
New: Hot Head. He looks powerful! And also his face

Water:
Series 1: Wham-Shell. Fun and pretty easy for me too find unlike Lightning Rod.
Series 2: Zap. His figure is very cool.
New: Chill. I HATE Thumpy.
Will post more later
