Sonic Battle

Sonic Battle is a fighting game spinoff in the Sonic series for the Game Boy Advance developed by Sonic Team. It released in late 2003 in Japan

Gameplay
Sonic Battle plays like a 2D fighter in a 3D arena similar to beat'em ups. There are no complicated combos or difficult button inputs to attack. When a character spawns in, they get to choose their special attacks in the form of Shot, Power and Trap. Players also choose which type of attack it's applied to, giving the move different effects.There is a special move mechanic called the Ichikoro Gauge. This when filled up turns the next special attack into a 1-hit KO unless blocked.

There are 3 types of modes for battles; Point, Survival and Time. Point is the first player to get X amount of KOs. Survival is the last character standing. Time is achieving a certain objective before time runs out.

The story mode has an overworld that each of the characters can travel through though the only time the player has access to the whole map is as Emerl. In each area, the player can fight other characters or  E-121 Phis to train or continue the plot.
