Mister Toad - Poison/Water Defender:
Travis LaMoreaux was always pretty "unexceptional" and he knew it. He barely made it out of high school and university was too much of a challenge for him, so he quit and went back home to Breaux Bridge, Louisiana to help out his folks in any way he could. He considered himself extremely fortunate when he was able to land a job at the new water treatment plant, considering he had no real skills or education. Ever the hard worker, and eager to do well on the new job, Travis did whatever the boss asked him. Even the day the plant shift supervisor asked him to help unclog an experimental chemical filtration system. Travis had been raised on the swamps so getting down into a vat of that mess didn't bother him none at all. He didn't know much about science and chemicals and all that sort of stuff. He figured he'd just get in, "git 'er done" and be out in time for lunch.
DNAngel - Dual Pistol/Invul Sent:
As a personal pet project of Dr. Jonathan St. John Smythe, who has always had a fascination with angels, the DNAngel initiative was kept off the S.E.R.A.P.H. books for reasons unknown. Brad Griffin had led a fairly normal life as the PPD SWAT commander until the point he was drafted for St. John Smythe's experiment but, well, as you can see - his life has become anything but "normal".
Pri-M8: Robotics/Electrical Affinity MM:
It's not completely known how it happened but, while under development in the Crey Advanced Robotics and Engineering (C.A.R.E.) lab, Pri-M8's programming encountered a glitch. Most evidence points to a firing of the former, believed to be the deceased hero, Dynamax's electrical powers which caused Pri-M8's self-awareness systems to repair and reboot, restoring some of the former hero's memories. The more he learned, while in the C.A.R.E. lab, the more he realized the rumors of Crey Industries using dead heroes for their scientific projects were most certainly true. Pri-M8 eventually escaped the lab, taking with him some of the other advanced, but slightly less self-aware, projects. He and his team now use a combination of raw robotics and Dynamax's powers to fight crime in Paragon. His memories are slowly coming back and he's gradually learning how to fine-tune his electrical powers into more and more useful abilities.
