Summer party Adagio
He would be super tan like almost orange. Instead of wings he would have two giant blue swim fins. He would also have a snorkle. On his back he’d have a tat saying “Holier than thou”

Summer party lance. His sword is a giant beach umbrella and his shield is like a surfboard
SP cath the shield is replaced with a sharp halcyon charged surfboard. Her B is like a water bubble amd her ult is a beach wave.
Another idea taking from an old idea: SP Celeste. One-piece swimsuit. Her staff woulf be an umbrella. Skill 1 creates a floating water ball at the chosen location. Skill 2 creates a water vortex. Ultimate is a tsunami.
