Kelvin is an elite member of the vampire hunting organization known as "The Hunting Party".

Elite Hunters are separted from the rest of the field agents by the nature of their accomplishments and kills, and Kelvin has racked up some big ones which include, but are not limited to:

   -Victor of the Glastonbury Vampire Cult Jamboree
    (2001)
   -Champion of the Northern Iowa Vampire Excursion
    (2003)
   -Hero of the Vicksburg VampVasion
    (2003)
   -Victor at the Poughkepsie Incident
    (2005 & 2007)
   -Hero of the Devonshire Incident
    (2004)
   -Champion at the West Kansas Vampire Assault
    (2005)
  

Kelvin the Lionhearted comes from an ancestral line of THP members to achieve Elite Hunter status. It was the family business, and he followed suit getting his first kill at age 9 with a plywood sword he made in order to play his favorite childhood game "Knights and Scoundrels", that he had a nun bless. The nun did it because she thought it was a cute little game.

He carries the family's ancestral blade, "Zwade van Dwaze Moed", which at over 400 years of age, has amassed quite a bit of anti-vampire aura to it, and has brought the end to hundreds of vampires in a flash of light and steel.

Not one to pile up kills with stealth and sneakiness, Kelvin is known for his rather loud way of jumping into battles, taking to using techniques mastered by the original user of his sword, Ronald the Glorious. Those techniques include boisterous yelling, obnoxious yelling, and a side of manly yelling.

There have been rumors of a cold war of sorts between Kelvin the Lionhearted and The Litigator of The Hunting Party, as Kelvin was one of the few Hunters vocally against Alexander Jagdhund being named The Litigator because of concerns Kelvin simply couldn't provide evidence of.

Time will tell if this becomes an issue with his current assignment: searching for the missing hunter Simon Polidori.
