Some of these characters have a better life currently, and others are still sticking to their origins because we haven't done much with them, or its just their personality flaws kicking in. Here's my thoughts on some.
Katherine Kane: Bruce Wayne's cousin, a prominent lesbian character and the superheroine Batwoman. Has family issues between a dead mother, a presumed dead sister and a father whom she has a mixed relationship with.
I feel that we could easily boost her martial in the training room, she has a high potential that hasn't been realized yet.
Rebecca Carstairs: A magic user/superheroine who operated under the name "Witchfire" who was also a pop star, actress and model.
I wanted to say that her Diplomacy is low in quest, but the description for her stat reads "that the public has all started to turn on her has left her a little depressed causing her people skills to falter a little", so that makes sense. She would have been a decent Diplomacy hero otherwise.
Karl Helfern: One of the first Batman villains ever created, operating under the alias "Dr. Death". Often dealt with various biological works but in his new 52 version, he was pretty explicitly a scientist interested in bone growth who wished to reinvent himself after the death of his son and turned himself into a terrifying bone monster.
If he can make a version that is malleable, reversible (to an extent) and doesn't make people run in terror, then he's free to test it on himself all he wants. At least he's getting to that point rather than jumping into a prototype version and getting stuck that way (like Vertigo's soldiers).
Mari McCabe: A superheroine who is often on the Justice League who operates under the name "Vixen" and draws open the power of an object called the "Tantu Totem" to grant herself the qualities/capabilities of various animals. Is originally from the fictional country of Zambesi and was involved in ending a dictatorship there.
Her Martial has been boosted like crazy, but I still think we should do the learning action for the Tantu Totem, before someone else taps into that power and we scramble to figure out what it is. Or worse they find a way to benefit from it before us.
Edward Nygma: The supervillain known as the Riddler. Edward Nygma had an abusive father who ended up instilling in him an obsession both with puzzles and riddles, and with being smarter than everyone else. Riddler is also often given computer skills and in the DCAU he was a former programmer who got cheated by his boss. Riddler generally tangles with Batman and is considered one of his smarter foes, but is also often undone by his compulsion to leave clues behind.
@King crimson Does Nygma still want to make games? Can we put him on the action to make videogames or improve them?
- Vivian D'Aramis: One of the two people to take up the mantle of the superheroine Crimson Fox. Vivian had superstrength and pheromone control and was spurred into becoming a superheroine after their parents were killed by a shady CEO of a pharmaceutical company. In the comics Vivian was killed by a supervillain.
- Constance D'Aramis: Has basically the same backstory as her sister and while she did take up the mantle solo following her sister's death, she was eventually killed by the supervillain known as Mist.
Another two heroines with high potential, but unlike Katherine they are doing great with their twin boost on Stewardship actions so no need for martial training. We may want to boost Constance's learning (currently 14) if we want to put them on learning actions to improve their results when making pharmaceuticals. Boost their knowledge in biology or chemistry and they'll get better results.
Eve Eden: Eve is a magic user who lost her brother to demons and since sought to get even. She initially attempted to work solo, before then going on to work with the Suicide Squad and then later teaming up and forming her own team of magic users known as Shadowpact of which she was a key member.
We need to get started on her revenge plan soon, learning about demons and learning to kill demons are two actions we have, we don't want to lose coop for not acting on it, she's giving us another action currently.
Arthur Villain: Arthur Villain is a Steel villain and is a smug prick who thinks he's smarter than he is, hiring Steel on when his identity was publicly known, as a publicity stunt while also working as a supervillain. Arthur Villain created a high tech suit which he gave to one of his minions who became the supervillain Skorpio and served as his bodyguard.
Good to know that Arthur can work on things like the exosuit or tech armors, bad that he'd probably sell the info to the highest bidder beneath our noses.
