Yes, in a friendly way.
ventus looks like roxas aqua has blue hair and is the only lady terra is the tall dark haired guy ventus=sora aqua=kairi terra=riku in a way...
No because kingdom hearts 3 is related to kingdom hearts birth by sleep but Ventus lost his heart in Ventus's secret ending when Ventus gave Sora his heart, Aqua put Ventus into this dome like where Roxas found Sora in it in kingdom hearts 2. Aqua bilt that to make Ventus heal in Aqua's secret ending.
Ventus, Terra and Aqua never had their hearts stolen, so they do not have Nobodies. However, Ventus' spirit was passed on to Sora, which is why his Nobody, Roxas, looks like Ventus.
Aqua actually doesn't save Ventus from freezing. Instead, during her fight with Xigbar's nobody Braig (in Aqua's story), Ventus manages to thaw himself out.
WEll kingdom hearts 3d looks like it may have something to do with terra aqua and ventus
Their relationship seems more like sister-brother to me.
Oh, I'm sure he does. Because think, if you pay attention to when Ventus watches the meteor shower and falls asleep, doesn't how Aqua frightens him seem familiar? If Ventus and Terra lived, I'm sure what happened with Sora, Riku, and Kairi would happen to Ventus, Terra, and Aqua too.
Ventus! Subterra may have the advantage but Ventus is the third best attribute(Pyrus as number one and Darkus as number 2).
Ventus, Terra, and Aqua
You get to play as Terra, Ventus{Roxas}, and Aqua.
Ven, Terra, and Aqua are the three main characters of Birth by Sleep. Terra represents the darkness like Riku, Aqua is like Kairi but equipped with a Keyblade, and Ven is like Sora but looks like Roxas, since Ven and Sora are connected.
Kingdom Hearts 3 Is Birth By Sleep With New Characters Terra Aqua And Ventus P.S I Recommend Using Ventus
