Klaus is very happy that you think he’s precious.
He is one of three Digimon Partners my Human character got in DnD-esque/Tabletop RPG Digimon game, though the times that he was a cute little demon child are long gone haha (Most of the time he’s a Piemon (still acting cute though))
He’s a cuddler and loves headpats and his mischievous side was more used to build traps for unfriendly digimon who wanted to raid his junkyard.
Ever since he found some relics from the
time when their worlds were still connected he dreamed of having a human
partner himself and waited in an old tollbooth which was carried over
to his home.
When Simon, a real life human child ended up at his place he couldn’t believe it and went to beg him to be his partner immediately overjoyed that he wouldn’t be lonely anymore.
His evolution line is Kuramon - Pagumon - Impmon - IceDevimon - Myotismon - Piemon - ChaosPiemon
