C.R.R.A.B.B.

Cyborg, Robin, Raven, And Beast Boy, otherwise known as C.R.R.A.B.B., is a mutated animal thing created by a Tamaranean multidimensional portal. This combination of the four aforementioned Titans has so far only appeared in the "Twisted" Teen Titans Go! comic.

History
To get the team working together, Robin has Raven, Cyborg, and Beast Boy play on a mat that he thinks is a fun game called "Twisted." However, it turns out that this is actually Starfire's inter-dimensional portal board, a transportation device from her home world. The four Titans are sucked into the mat an resurface as a horrific, unified creature. After several attempts to change back, the beast, now calling itself "C.R.R.A.B.B.," is forced to live as a grotesque superhero blend.

Things get better, though... C.R.R.A.B.B., a combination of four heroes, has quadruple the powers of any one Titan on their own. Starfire, through strenuous and somewhat ridiculous tests, is able to gift the monster amazing levels of dexterity, strength, constitution, wisdom, endurance, and charisma. With all of these attributes, the H.I.V.E. Five is an absolute cake walk for C.R.R.A.B.B. to beat. Eventually, Jump City is entirely free of crime, and the mayor even awards the mutant a commemorative key ring and an early retirement.

With nothing left to do, C.R.R.A.B.B. slowly starts to lose its marbles. The four Titans trapped within the single body can still think independently, causing C.R.R.A.B.B. to constantly argue with itself. Watching the beast go crazy, Starfire suggests they go to the pool for some relaxation.

Unfortunately, nothing can cheer C.R.R.A.B.B. up. A splash of water from the pool gets it all wet, and so Starfire lays down what C.R.R.A.B.B. thinks is a towel. Depressed and wishing for death, the monster lies down on the mat, which is actually the Tamaranean portal board from earlier. Starfire sets the configurations on the mat, and C.R.R.A.B.B. instantly enters the board... moments later, out pops Robin, Beast Boy, Cyborg, and Raven, all free from each other (for the most part; a sweater C.R.R.A.B.B. was wearing still bonds them together). It turns out Starfire could change them back the whole time. Wow.

Characteristics
Before the final transmogrification of C.R.R.A.B.B., the portal board spat out two other versions of it. The first mutant had the torso Cyborg, and Robin's head was pushed through the chest plate. The beast had four arms, including a Robin arm, a Robin LEG, a Cyborg arm, and Raven's entire body. Beast Boy, who was in the form of an octopus at the time, takes up the head and leg area.

Seconds afterward, C.R.R.A.B.B. reforms, once again with the body of Cyborg and the legs of Beast Boy. This time, however, Raven gives a little more contribution, offering her arms and cape to the monster. Robin now owns the head area, and his utility belt is also included, which should come in handy.

The last version of C.R.R.A.B.B., the one that it stays in until the final break-apart, borrows the legs of Robin and his yellow belt. Cyborg once again only contributes his chest, and Raven's arms and hood remain on the monster. However, now Beast Boy has regained the prized body part, the head. Having reverted back to a normal green boy, at least normal for him, he also dons Robin's mask.

Trivia

 * In the episode "Power Moves", Robin takes over Cyborg's body and can be seen inhabiting his chest. The first form of C.R.R.A.B.B. is very similar, as Robin's head can be seen sticking out.
 * Although the final form of C.R.R.A.B.B. wears Robin's mask, for some reason Beast Boy's pupils can be seen through it. Robin's can't.
