All: remember, in the current non canon story, use of powers by the core cast (outside of Karen/Carole) is MODERATE. These are young ppl who are still "in training", certainly not combat hardened or seasoned like mainstream six. Courtney's mystical powers or implied but will not be seen openly except for on two occasions in the story. the characters also have their individual non super powered talents that make them unique.
Morgan/Courtney: Time/Space Teleporting (stepping discs) herself , other people or objects to/from; mystical abilities [implied] - manifestation of magickal abilities require use of an actual SPELL & or/talisman. while her teleporting power seems to be well controlled...the FARTHER she attempts to teleport, the greater margin for error. teleporting objects TO her requires her to see the actual target. Psi-Screened BUT Nicolas can detect her emotions & vital signs. *LIMBO is the big secret she & her mother keep from everyone about her powers, fearing ppl will think of her as a DEMON b/c her power is to control the stepping discs which originate in Limbo, thus linking her to the sorcerous realm. Nicolas is the only one of the core to have seen Limbo & no one believes him about it.
Ava: Weather manipulation (e.g. - temp control, gusts of wind, bolts of lightning, clouds of fog, blasts of thunder for physical impact)- emotional control needed for most effective display of power. complex things like SEVERE storms or small scale tornados take extreme effort & would leave her exhausted
Delilah: Manifestation of LIGHT across the spectrum (e.g. - "lightshows", strobe effects/flasbulbs, photon blasts & laser blasts, perfect vision)- photon & laser blasts require great effort & concentration. has the advantage of long range & light speed activation if she can focus & time her photon/laser blasts just right; is immune to the blinding effects of her lightshows/strobes/flashbulb effects
Nicolas: Superstrength (not defined but certainly NOT class 100 @ this time) & telekinesis but primarily used to augment his physical abilities including leaping (a'la the hulk but STILL in training to control trajectory & landing); durable yes but NOT nigh invulnerable. vulnerable to sonic attacks or strobe effects when trying to focus to use TK in more intricate ways. Telepathic ability but limited to sense thoughts/emotions of others (friendly or hostile).
