This was the first HUD for the Sonic Battle game, [short for Heads-up display]. Firstly, the bar was yellow, and the top green bar was just a little less thicker than the main one. The area with the name would go off to the left and attach itself to the side, getting rid of tht space between it.

Most importantly, it didn't even work! The number below it would tell you how many hit points you had left out of 200.

The second HUD was a little different, it actually worked for one, but also the triangle at the end of the black section was chopped off, and the green bar was extended.

This is the final bar from the final game. The back area and bottom bar have merged together to form into one, the yellow bar has now turned orand and lost it's outer white border. The section with the name has been enlarged in height, and the green bar has shrunk to less than half its original size.
