The Team Blast Gauge is a game mechanic that appears in Sonic Heroes. It allows the player to charge energy for the Team Blast maneuver.
The Team Blast Gauge is presented as a horizontal gauge in the right upper corner of the screen, above the Formation Leader icons.
The Team Blast Gauge displays how much energy the player has collected to perform the Team Blast, which is displayed by a blue bar inside it. To fill it, the player can collect Rings or Team Blast Rings, defeat enemies or use Thunder Shoot. During the battle with Metal Overlord, the Team Blast Gauge can as well be filled by countering Metal Overlord's attacks.
Once full, the Team Blast Gauge gets be covered by a yellow bar with "TEAM BLAST" written on it and one teammate will say a quote. The player can then press the White Button// to unleash the Team Blast. After usage, the Team Blast Gauge will reset, which is signified by an orange bar decreasing on the yellow bar of the gauge. Once it is gone, the gauge reappears. To use the Team Blast again, the Team Blast Gauge must be refilled and had time to reset.

There is a glitch which can be performed that causes the Team Blast Gauge to fill up much faster.

If done correctly, the Speed character will float into the air without the Thunder Shoot actually being performed and a unique sound effect plays.
