051 Manga

Manga is a robot.

The G1 figure came out in Crew 4.  He resembles some sort of Japanese manga-style robot (or mech), particularly those from the Mobile Suit Gundam franchise called Gundam SD.

In Japan, manga refers to a simplified style of drawing or cartooning.  In the US, manga refers to any comic coming from Japan.

In G3, Manga became a Transformers parody.  In one version, he is specifically an Optimus Prime parody.  A second version is black, gold, and red.  This version is probably a nod to Grimlock.  A third version is green and purple.  He resembles Devastator.

In the Zoods Crew 2, the green-and-purple version came with a zood named Click.  He is a mouse.  A computer mouse. The trackball design of a hand-controlled pointing device -- the hardware that we call a mouse -- goes back to 1965.  

For some reason, when Spin Master "Re-Leashed" four of the zoods, they gave Click to Minga instead of Manga.
