Rash was originally a human game tester named Dave Shar, who much like his buddies was transformed into a toad upon entering the Gamescape. Rash is the coolest toad (so he says), being the most extroverted and flamboyant of the team. He is easily identified by his green skin and shades, wearing red ninja ribbons on his arms and studded kneepads. He is the most agile of the team, using sharp weapons on his Smash Hits.
Rash has been playable in every Battletoads game except for the Battletoads Game Boy sequel. In Battletoads, he is the character that you play as when in first-player mode. He does not wear his shades in-game, but wears them in his profile screen. Rash also appears as a playable guest character in Killer Instinct for the Xbox One as the first character in Season 3 in March 2016.
