Klaus Heisler is a fictional character from the animated television
series American Dad! The Smith family's hapless and saturnine
goldfish, he is voiced by Dee Bradley Baker and first appeared on
television, along with the rest of his family, when American Dad!
initially premiered on Fox on February 6, 2005 with the series' pilot
episode. Klaus is actually a man in a fish body. He was once an East
German Olympic ski-jumper until his brain was transferred into the
body of a goldfish.Klaus was once an East German Olympic ski-jumper
until his mind was transferred into the body of a goldfish during the
1986 Winter Olympics by the CIA to prevent him from winning the gold
medal, leaving him trapped in the goldfish's body. Klaus still has not
come to terms with what happened, at times malcontent and gloomy. Not
confined to his fishbowl, Klaus is often seen uniquely scooting
himself about the Smith residence, reclined in a glass of water. In
the early seasons, Klaus had an obsessive crush on Francine Smith and
often made sexual advances to her, but stopped after the events of
"Finances with Wolves", in which Stan saves Klaus' life despite his
attempt to have sex with Francine. For much of the later seasons, the
Smith family and particularly Roger have been shown to treat Klaus
with disdain, take him for granted, and even mistreat him. In earlier
seasons, Klaus was shown to be the smartest and most reasonable
character in the family, often trying to warn or advise the Smiths of
their wrongdoings of selfishness, stupidity, or recklessness. But this
slowly changed as the series progressed, and in later seasons Klaus is
shown to be much more prone to being crazed and senseless.Klaus and
Roger's relationship is best described as a sibling rivalry. At times
they hate each other and at other times they get along well. Roger is
seen to be incredibly spiteful toward Klaus and insists on trying to
make him feel despised, saying things like "You can't participate
Klaus, I hate you. I say that not out of anger but as a fact" in
"Great Space Roaster" and "It's like you want to be kicked out of this
family" in "The One That Got Away". Klaus does things to get Roger
into trouble for his amusement, like when he tricked him into eating
Francine's potato salad in "Deacon Stan, Jesus Man". When a horrified
Roger asked why Klaus would do something like that he just laughed and
said "I'm German, it's what we do." In "A Piñata Named Desire", after
Klaus made a comment about acting, Roger simply knocked Klaus's fish
bowl across the room, smashed it against the wall, and walked out of
the room as if nothing had happened while the fish lay gasping on the
floor.Among everyone else living in the Smith household, Klaus is very
much the most aware and sensible of Roger's contemptuous, abusive, and
insanely-vindictive nature of selfishness and lack of morality and
occasionally tries to warn the rest of the family against listening to
or getting involved with him. Such instances, however, are ignored by
everyone's naivety and general inability (or lack of interest) to take
most matters seriously or remember that Klaus is a "man in a fish's
body" rather than just a mere talking goldfish, as said in "Dr.
Klaustus". Klaus Heisler Biography, NetWorth, Height, Age, Weight, Family, Married, Son, Daughter
