(Brief and loose, but the details will come out in play.)
Name: Thor Odinson
Age: 1000+
Appearance: 6’6”, blonde hair, close-cropped beard, arctic blue eyes. Powerfully muscled. Normally clad in Asgardian armor with Mjolnir in hand or hanging from his belt.
Abilities: (Condensed version) Super strength, invulnerability, flight, weather manipulation, Asgardian physiology, magical connection to the mystical Mjolnir.
Personality: Multi-faceted. Brave, undaunted. Prideful. Often passionate to a fault. Sometimes the instigator, sometimes the diplomat, dependent upon the stakes and his level of irritation. Respectful of the many races and cultures of Midgard (Earth) while also holding himself apart from and (occasionally) above Midgardian politics.
Bio: True-born son of Odin, heir to the throne of Asgard, Thor has spent past centuries growing to adulthood and adventuring across The Nine Worlds with his closest companions on some sort of glorious quest or another. Only in recent years has he been forced to face true responsibility for his actions and for the fate of Asgard. He has also recently taken a special interest in the happenings of Midgard, partly for personal reasons (a certain quirky astrophysicist?) and partly for political.
Learning of recent events on Midgard from the gatewatcher Heimdall, Thor travels earthward to investigate the dangers that threaten his mighty Midgardian allies.
Misc.: Basically following the movies as far as backstory and assuming nothing major has happened in Thor-verse since the defeat of Malekith. Thor has mainly been occupied mourning a dead mother and "dead" half-brother, and overseeing the rebuilding of Asgard.
