Garsaurus REX Attacks!

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

Summary[]

Professor Chang blasts Beast Boy with his new G.A.R.T.H. Gun and transforms him into…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!^[1]

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.
