@The Kid Lantern Accepting?
From what I can gather here you're wanting to make a character that is both Raven and Trigon all rolled up into one. Although with the current line up of heroes, even with a team, Surd is just completely overpowering in my mind.
In his avatar form of an old man he has fire breath, smoke breath, the ability to regenerate by channeling energy from open flames, can sense open flames, can temporarily summon Surd's powers through chants and rituals and can transform into Surd by channeling the sun's energy. Not to bad as power sets go. And then there's Surd. Fire breath, smoke breath, super-strength, the ability to set things aflame by touch, ability to regenerate by channeling sunlight, he has a large flaming sword, skin as hard as obsidian and as durable as thick leather, a super-heated body that can evaporate liquids and melt solids upon contact (going back to that setting things aflame power), and can grant free thought to open flames. Oh, also he's 20 feet tall.
His weaknesses as Surd are shade(?) and only Gods and Demi-God can stand toe-to-toe with Surd. And I'm assuming that as the avatar he has normal human weaknesses that can be healed by channeling the energy from open flames.
Right now we have no real heavy hitters anymore that could stand up against Surd, even as part of a team. I would suggest limiting the powers some. In the avatar form I would limit his powers to smoke breath, the ability to regenerate by channeling energy from open flames at the cost of extinguishing the flame, the ability to sense open flames and the ability to temporarily summon Surd's powers or transform into Surd through chants and rituals. The chants would grant him the powers of Surd for a short period of time, maybe only a few minutes at a time, while the rituals would take time to prepare and perform so they would give the avatar Surd's powers for longer times. Each power would also have a different chant or ritual to perform.
As for Surd, I would let you keep fire breath and smoke breath. Super-strength you can keep, maybe expand on it some and give him some limits to how much he can lift, and his durability he can keep, maybe compare what level of durability your wanting to an already established comic character just for easier reference. The ability to set things aflame by touch is the biggest thing I have problems with, because if I could do that and I got into a fight I would do nothing else so no one could touch me, as a compromise I would suggest limiting this power to the sword only. The granting free thought to open flames is something else I could see becoming a problem if every flame in the city suddenly is given life, maybe just limit how many flames he could give free thought to or how large a radius around him that he can control the flames.
Another thing I would do is limit his height depending on how Surd took form. If he takes from through the power of a ritual performed by the avatar then limit his height to something between 10 and 15 feet, he would have his powers but be confined to a smaller body for the duration of the ritual. If he takes a more permanent form from like an amulet of some kind he becomes his true self, between 20 and 25 feet tall, with all his powers until the amulet is removed and he returns to his avatar form.
This way you can add more to your weaknesses while still keeping him as one of the stronger characters in the RP, this way will also cut down on some of the more op power sets while still letting your character retain them in some form. You could also add in some storylines where the avatar is searching for an amulet or some kind of powerful object to manifest Surd in his full power. By then we may have some more heavy hitters to make it more of a fair fight as well.
Sorry guys, I'm gonna have to drop this rp :( I'm just not motivated to continue, especially with work tiring me out.
@Jotunn Draugr Actually @Parfex had planned on their characters having history, so he might wanna get in on it.
~KL~
I'm here, I'm having trouble coming up with a scenario to have Chok-Lad confront the STRIKE team without having him just want to rip them open and take Picasso back.
@The Kid Lantern
Yea. I just don't know what the heck to do next. :/
I'm working on a post to move things forward with the energy beast headed towards the empty Mercury Mall! @Lord Wraith and @Hillan if you guys are still around we should cross paths!
