- "The ranks of the Delta 3 squad comprise a who's-who of the obscure; heroes you've never heard much about, mostly because they are often called in to fight when the odds of success are slim. Bluntly, they tend to burn through their roster at a frightening rate. Members of Delta 3 are a close-knit group who are more concerned with bursting in, guns-blazing, and doing their thing, than they are concerned with, say, strategy. Without Grudge around, his team would be nothing more than a bunch of thugs with a death wish. Despite their disregard for planning and the bodycount their team mounts, they are amazingly successful. If it's a lost cause, Delta 3 will be there, winning the day with sheer guts and determination."

The Delta 3 team was a sub-group of the elite Hero Factory Delta Team, currently operating under the leadership of Darren Grudge. This team had a history for generally being composed of tougher, battle-hardened heroes.
Leadership of Darren Grudge
Unlike the majority of Hero Teams, the Delta 3 Team was created shortly after Darren Grudge, a Veteran Hero, returned to the the Assembly Tower, hardened by many years of warfare and experienced in most forms of combat. Under his leadership, the group became closely linked with the early Delta 4, with Grudge and Tom Knight becoming close allies.
Unfortunately, several decades ago, Knight led the Delta 4 team on a mission to confront a rebellious band of villains, which left them outnumbered, causing their swift defeat and murder at the hands of the group of villains. Knight, however, was critically wounded but was able to return to the Hero Factory Assembly Tower in the group's Dropship. When the vehicle crashed in the outskirts of Makuhero City, he was rumored to have been killed.
To compensate for the loss of his closest ally, Grudge was partnered with a young female rookie named Georgina Scope, who he trained extensively. Eventually, Scope achieved a Veteran status and shared her team leader's fascination with mechanical engineering. It was around this period that the pair of Heroes began hunting down hunting down a kingpin controlling a string of new crimes in the Mutter's Spiral galaxy. After capturing and tormenting a number of assassins, it was decided that there was in fact a figure responsible for the destabilization of the space sector, though the Hero Factory would not allow them to pursue the issue further due to Grudge and Scope's unorthodox methods. Little to their knowledge, the employer would one day be revealed as "Scratch".
After several years of active patrol, however, she expressed her fascination with intergalactic life and desired to permanently patrol her own sector for criminal activity. The female hero was given armor that was designed to withstand conditions in deep space, such as extreme temperatures, radiation, and galactic debris, and is also outfitted with magnetic boots and an advanced apparatus.
As the only active member of the Delta 3 Team when the Brains controlling creatures native to the planet invaded Makuhero City, Grudge formed an alliance with Jenny Sharp, the acting leader of the Delta 4 Team while Trooper - who had been promoted to team leader by this stage - was absent.
