Robert John Blotzer (born October 22, 1958) is an American musician best known as the drummer for metal band Ratt.

Blotzer had heavily denied the claims and had said they were a bunch of "pathologic lies", adding that Pearcy was a "sick person".

[citation needed] On September 2, 2012, it was announced Bobby would be joining Geoff Tate's touring lineup formed after the latter's dismissal from Queensrÿche,[4] but he left on January 25, 2013, to return playing with Ratt.

Blotzer asked Sinners' singer Joshua Alan, guitarist Michael "Doc" Ellis, and bassist Scott Griffin to join him in forming a new version of RATT.

[8] In October 2015, DeMartini sued Blotzer for falsely advertising his "tribute band" as the real thing.
