Prominence is a chill, yet easily annoyed dude. Most of the time he tries to stay alone, and he hates being touched, which is why he keeps his rays active all the time (his rays produce an orange plasma, much like the orange plasma during, well, a Solar Prominence. If you touch it, you won't feel anything, as your hand will be turned to ash in less than a millisecond.) His brother, Solar Flare, looks almost identical, except his plasma is more unstable, and he as a whole is more aggressive.
