Looks: he is a "construct" of some sorts, an anomaly from the universe brought to life by wild magics, his shape is vaguely humanoid, has several small "cores" running trough his being, he's surrounded by a purple gas that composes his body, his entire body is completely inmaterial except for the cores, wich rarely stay in a single place for more than a micro-second making their precise location a nigh-impossible thing to know (Just imagine this).

Personality: Despite not being fully alive, he has shown curiosity towards certain things, most notably the space where he comes from, it is very common for him to gaze into the heavens for hours, even days; he's capable of speech, and speaks english, how he does this, is unknown, altough he guesses the gas within him and the debris that he absorbs are what enable him to do this.

Background: Cataclysm was the first thing he perceived when he crashed into the world, as several pulses erupted from him and caused massive damages to the city, causing tremors, tidal waves and storms, nearly demolishing it, all this without knowing, as he gained his conciousness, he phased out of the city and started to wander around the planet, ignoring what just happened, as his intelligence was practically non-existant at the time.

Abilities: he is capable of manipulating gravity in a variety of ways, most commonly making orbs to crush or "stretch" something into thin air, or throwing things great distances, as his form is gaseous and the only "physical" part are the cores, his movement speed can reach near-light-speed, making it look like he is phasing in and out of existence, contact with the cores, or what Cataclysm carries within him is deadly, as the kinetic energy within them is far more than enough to destroy planets and turn them into cosmic dust.
