Chromedome

In most universal streams, Chromedome (aka Tumbler[1]) is a comparatively quiet academic. Originally a number-cruncher at Cybertron's Institute for Higher Programming working on ways to improve the processing power of the Transformers' computerized minds, Chromedome found himself forcibly dragged into the Great War when a Decepticon attack destroyed the facility. Chromedome put his work to use programming Autobots so they could outsmart their Decepticon foes, but alas, only wound up fostering an intellectual arms race of sorts, in which both sides competed to repurpose the newest advances in programming into military advantages.

Ground down over the years by this inevitability, Chromedome has come to accept that war with the Decepticons cannot be prevented—but only won. Well-versed in the mechanisms of the Cybertronian mind, Chromedome has been known to specialize in mnemosurgery, the science of manipulating the Transformer brain and the memories within.
