Contrary to his relatively modern three-piece suit Composer wears, Playwright assumes the appearance of a typical Netopian well-to-do... a handful of centuries ago. His face appears the same, but his general facial expression of scornful aloofness makes it seem like someone entirely different. Upon his honey-blonde locks that have suddenly grown into a much longer ponytail, he wears a very tall, very ridiculous black hat, with a few large feathers tucked into the brim. Covering his torso is a traditional black tunic, with slightly raised shoulders and gold embroidering. His arms, as the tunic doesn't cover them, are shrouded in a puffy purple shirt made of what appears to be silk, with frilly white cuffs. The hem of the purple shirt forms a second sort of 'skirt' beneath the tunic's. And below that...are tights. Tight, shiny black tights, capped off with simple purple shoes. His hands are devoid of anything to replace Comp's conductor's baton, but he doesn't seem to mind gesturing with just his hands.
The same effects as usual apply from Comp to Playwright, in terms of the out-of-control power surges. His clothes tatter to the point of being little more than rags, and the streams of light start to violently burst out of him. The insanity is also still present, but with a twist that shall be explained below.
Technically, a .GMO doesn't usually override a Navi's personality, though it can in some cases. It does not affect Comp's personality in the slightest, but being the eccentricity that he is, Comp decides to playact every moment he's in Playwright. He will rapidly switch between a standard narrator's tone, using a low, enthusiastic voice, and any range of 'actors' he so chooses. He overemphasizes his speech to ridiculous limits, and tends to constantly gesture dramatically. Despite all this silliness, it is still Composer's personality.
The interesting glitch is the reaction of the power breakdowns to the .GMO. Normally, Composer's state of insanity is a giant mishmash of crazy, with no specific focus on how he's crazy. .GMO files, on the other hand, tend to streamline the insanity down one line of focus. In the case of Playwright, while insane, he tends to act as though he were under the effects of several extremely heavy drugs. Twitching uncontrollably, flying into uncontrollable rages, heavily hallucinating, all the works. He is generally incredibly aggressive while insane in Playwright.GMO, and is much less hesitant about using Melee-type chips.
Battle Fluff: Many, if not all of Playwright's attacks are done by use of props. For example, swords would be wooden replicas, fire would be made of flapping ribbons, explosions become large flashes of light and smoke machines, etc. It's all generally very humorous, and very overdone. And Composer's inwardly laughing his head off at it all.
