Garsaurus REX Attacks! is issue #21 of Teen Titans Go!.


Professor Chang blasts Beast Boy with his new G.A.R.T.H. Gun and transforms him into a Garthzilla. When the giant green monster starts trashing the city, the Titans have no choice but to bust out their secret weapon: the Titans Go-Bot 5.



  • As Starfire saves a few kids from Garthzilla's tail, Bumblebee calls out "He may look like a dinosaur, but he's not here to sing song and teach you the alphabet!", which may be a reference to Barney, the titular character of children's television series Barney and Friends.
