Sure is. Garfield Minus Garfield reimagines the original Garfield comics in a creative and sometimes humorous way. It's gained a following among comic enthusiasts.
I don't think there is a Garfield comic where Garfield died. Garfield is a popular and long-running comic series, and typically, the main character like Garfield doesn't meet such a fate.
In the 'Garfield and Friends 20 Garfield Stories', we can expect a collection of humorous and endearing stories. Garfield is known for his sarcastic remarks and his love for a laid - back lifestyle. The stories could cover his battles with the alarm clock in the morning, his envy when Odie gets more attention, and his creative ways of getting into the fridge to steal some lasagna. It's all about Garfield's world, his relationships, and his never - ending pursuit of comfort and food.
Garfield is the central figure in 'Garfield and Friends 20 Garfield Stories'. He is a cat with a big appetite for lasagna and a penchant for sleeping. Odie, the somewhat clueless dog, is also a main character. And we can't forget Jon, who takes care of Garfield and often finds himself in comical situations because of Garfield's antics.
Perhaps in this fanfic, Griffith has turned into something truly evil and a threat to the world Guts cares about. Guts, being the warrior he is, might feel it's his duty to put an end to Griffith to save others. Also, Guts could be driven by his own sense of justice. If Griffith has wronged innocent people, Guts may decide that killing him is the only way to set things right.
It depends on the specific fanfic. Some fanfics might have Guts killing Griffith as a major plot point, while others could take a different direction and not have that happen at all.
