Sony

From Wikitokyo, the unofficial Megatokyo wiki

Sony is a major computer and electronics manufacturer and, in the world of Megatokyo, Ed's employer. In the early comics we see Sony making a bid on the hostile take over of Hell, but will not accept Satan's high price on such an 'out-dated operation'.

See the Wikipedia entry on Sony for further information about the real company.

[edit section] Ping

Sony are also the manufacturers of Ping. As a result, Dom has been sent by rival company Sega to get hold of her. Much to Largo's surprise, Ping is 'pretty soft for a Sony' after she offered Piro her lap to sleep on. Though it was not until after she passes into Piro's possession do the Sony Labs finally run a simulation of her rejection protocols. As a result, Largo's pleasant surprise evaporates into fear and wariness.

[edit section] P4216A Killtrunk

A huge piece of kit Ed is kitted out with from around the time he takes over Largo's English class. Carried in a large briefcase and a massive drain on the power grid, the Killtrunk is used by Ed in an attempt to eliminate Ping. But it is presumably destroyed when the Space laser destroys the school.

[edit section] Kill Balls

Kill Balls are a special offensive unit. Initially Ed uses one during the city battle with the Zombie army. Upon encountering Miho, he acquires greater numbers in an attempt to defeat her.
