Oh yeah, may as well dump my own characters here.
Velocity
Dr. Grant Adams, renoun paleontologist and older brother of Martin Adams (aka Anubis), is most famous for the research expedition he led into Insula Primalis after the Citizens of the Sun had left. What few people know, however, is about the unofficial expedition he embarked on my himself years prior. Taking a small boat to the far end of the island, a young and dangerously eager Grant braved the ilsand's dangers and risked its locals just for a chance to study the magnificant beasts that lived there up close, and he did so. Thanks to all the cautions and precautions he took, he was able to survive on the island and avoid discovery for long enough to interact with several species and even befriend the leader of a raptor pack whom he nicknamed Ellis. His stay didn't last too long, however, as one day, when he was studying Ellis, a Citizen of the Sun happened upon them, and reacted with a psychic attack! Luckily the only casualties were a couple of devices that moniter brainwaves and Grant managed to escape and get off the island.
Years later, Dr. Adams returned to Insula Primalis, this time with a team and government funding to back him up. Upon arriving, he was surprised to not only be quickly reunited with his old friend, Ellis, but also to find that she had gotten much smarter, to the point where she could even communicate telepathically! Eager to explore the world outside her former home, and more than happy to put her newfound sapience to use, Ellis joined the Sentinels of Freedom the moment she heard about it under the name, Velocity.
The Penitent
Angelo Dantes was once a professional boxer in Roma, Italy, but he was not a nice one. He fought dirty, he made deals, he took dives, he did whatever would get him the money. over time he just got meaner, until he became notorious in the ring for his fakeouts and illegal moves that got him banned from more than one tournament. He continued to get worse with no idea that he was under the influence of Bezaliel the Deciever, so by the time his body started to change, his mind was already fully corrupted. Angelo Dantes was once a boxer, soon he was nothing more than a demonic thrall in Apostate's army.
When Fanatic fought against Apostate's assault on the Vatican, he told her something so chilling that she left during the fight. When she returned, clad in new, she charged right back at Apostate, effortlessly blasting any demons that got in her way. She was so focused on her opponent, she didn't notice that a fiendish pugilist she put down didn't stay down.
Angelo knew he should've died that day, but that blast of holy light did not destroy his body like intended, and instead broke Apostate's control over him, freeing his mind and returning his identity. Angelo took this as a second chance, and did not let it go to waste. He quit smoking, quit drinking, quit gambling, joined the church, and overall turned his life around. He may still have the appearance (and power) of a red demon, but the Penitent is now one of the nicest, most devout people you'll ever meet.
Charm
Matt Whitman (name pending) had always been popular growing up; he won prom king, was offered several scholarships, and aced every job interview. He wasn't just sociable and good-looking, though, he was also helpful. Whenever someone had a problem, he always knew how to talk to the right person to get the job done. The job he had in digital media wasn't anything fancy, but he liked everyone in his circle and was content with the way things were.
Then OblivAeon happened.
When the Freedom Five became the Sentinels of Freedom was during a time when new heroes were in high demand. The near destruction of the universe made a lot of people reconsider what they wanted to use their powers and skills for, and Matt was one of them. He used his connections to get himself a good physical trainer and, when he felt he was ready, put on a mask and started calling himself Charm. While decent at combat, his true skill was his charisma, knowing how to pull the right strings to solve the crime or get what he needed to save the day or, at the least, make it that much harder for bad guys to want to hit him.
