Color TV-Game 15
The Color TV-Game line of consoles was a series of consoles produced by Nintendo in the late 1970s, with all consoles only being released in Japan. The Color TV-Game 15 was the second iteration of the console, released in 1977, and features fifteen game variants over the six offered by its predecessor, Color TV-Game 6.
The Color TV-Game series features the Light Tennis game, which was among the numerous Pong clones produced after the production of Pong by Nolan Bushnell's Atari in 1972. The paddles move in linear paths with the same consistent speed, in homage to how the original game was controlled by using microswitches. The Tennis B (テニスB, Tennis B) variant serves as the basis of the game's appearance in the Super Smash Bros. series, according to the PAL SSB4 trophy description.
As an Assist Trophy
The Color TV-Game 15 made its Smash Bros. debut as an Assist Trophy in the fourth game of the series.
Upon being summoned, a single white paddle appears above the summoner's head, before splitting into two paddles from Light Tennis. It will then launch a large pixel "ball" between both paddles, playing a game of Tennis B by themselves. The launched ball will bounce off any surfaces it touches, and deals extreme knockback to any enemy that touches it directly; reflecting a ball in play often grants it OHKO power. Additionally, the paddles themselves reflect projectiles for the opponents of the summoner and deal knockback to enemies that touch the paddles, while not inflicting any damage.
During the "game", an aesthetic score appears above each paddle, keeping track of how many wins each paddle has. The paddles will attempt to keep the ball in play as long as possible; if one paddle gets a point, the other paddle will shake up and down in dismay before another ball is launched.
The Color TV-Game 15 trophy appears in both versions. In Super Smash Bros. for Nintendo 3DS it is a Challenge reward, obtained by playing 50 combined hours in the Smash mode. In Super Smash Bros. for Wii U it is part of the Memorabilia Trophy Box.
