T-Wrecks

Former attack specialist T-Wrecks was stationed in sector 17 of the Mirtonian constellation, but returned to Cybertron just in tim

e to be reformatted by the Oracle, and become leader of the new Dinobots. He is a staunch defender of the Maximal cause, and his prowess on the battlefield has led his troops to nickname him "Big Rex".

In The Comics
The Dinobots were sent to the planet Arkus by the Oracle in order to awaken the "sleeping giant" for a mysterious purpose. However the mission was a fool's errand, arranged by the Quintessons, and designed to destroy the Dinobots. The planet held prisoner one of their most dangerous creations, the energy-drainingTrans-Organic creature known as the Dweller. Betrayal

T-Wrecks, Triceradon, Terranotron and Dinotron survived their encounter with the Dweller and managed to get off-planet. They met up with Devcon at Spaceport CSSB-16, and joined him on his quest to hunt down Cyclonus. Disclosure

 * T-Wrecks (Ultra, 2000)
 * Accessories: 2 spring-launched blade-missiles, water squirter
 * T-Wrecks is a redeco of the Ultra-class Beast Wars Predacon Megatron. He transforms into a Tyrannosaurus rex, with a water-spraying gimmick inside his dino-mode mouth. In robot mode, his left arm has a lunging/snapping claw gimmick, plus he has a pair of hip-mounted spring-loaded missile launchers. He retains the "mutant head" gimmick as well: a pair of bat-like "wings" on his helmet that swing forward to cover his face as a "battle mask" (a feature which, unlike the original Megatron's, was actually depicted in fiction).

Trivia

 * Several hints in his bio suggest T-Wrecks may be the same character as the Generation 1 Dinobot Grimlock in a new body, such as being a "former attack specialist" (his Beast Warsfunction) and some references to Generation 2. However, he was not portrayed as such in his fictional appearances.
