Yes bluestar of thunderclan knew Jake firestar and scourges father
No, Jake is not Sunstar. Sunstar was a different cat who was the leader of ThunderClan during Bluestar's younger days. Jake is a loner who befriended Bluestar and fathered her kits, including Firestar.
Firestar's father, Jake, is revealed in the Warriors book series through the storylines and family trees presented in the novels. Jake is a former kittypet who mates with Firestar's mother, Nutmeg. The characters reference Jake as Firestar's father in the series.
Scourge's father is Jake, a kittypet (housecat). He is the father of Scourge, Firestar, and Socks and Ruby.
No, Bluestar, the leader of ThunderClan in the Warriors book series, does not know Scourge, who is the leader of BloodClan in the same series. Their paths do not cross in the story.
Moonflower is their mother and when i mean their i mean Bluestar had a sister Snowfur just as she had her son Whitekit (Whitestorm) she was hit by a monster, but yeah, Moonflower is her mom she died in a battle with Windclan, if you want to know more about her early life read Bluestars Prophocy.
There is no Jake Vader that I know of
Tigerclaw tries to kill Bluestar in Chapter 37 of "Forest of Secrets." This is when Tigerclaw reveals his treachery and attempts to take over the leadership of ThunderClan by attempting to murder Bluestar.
Jake is a ginger cat and he seems interested in the forest and we know that Scourge's father was that. We don't know for sure but it just seems really likely. -------------------------------------------------------------------------------------- We know that Scourge's father is Jake, and Erin Hunter revealed that Jake is Firestar's father also. Which means that Bluestar met one of their future leader's father when she was an apprentice. Which also means that Firestar killed his half-brother, Scourge, over a fight for the forest.
Jake is a Tweenie....... (is that how you spell it) I think so but I know Jake is a tweenie :-)
I don't really know, but I think it is Bluestar and Spottedleaf.
Bluestar's warrior name was Bluefur.
We don't know. This is a better question to ask the Erin's. They were great cats but all cats have to go to StarClan. And without Fireheart becoming leader we don't know what would have happened to ThunderClan in the future.
