This is what I think: Amphibia will have 3 seasons with Season 3 being the last. Season 1 focused on Sasha, Season 2 focuses on Marcy, and Season 3 culminates The Frogs, toads, and newts. After the final battle in hopefully a two-part finale where Anne, Sasha, and Marcy defeat the “final boss”, The three species make a peace treaty with each other. In the last five minutes, Anne gets an emotional farewell from the frogs, Sasha and Marcy give a salute to their species with Grime actually crying. Anne and the Plantars give each other one final goodbye with tears falling from their eyes. Anne, Sasha, and Marcy stand in the center of the three species with the Calamity Box all fixed up. Anne opens the box and they got beamed out while saying their farewells. The three girls end up back on Earth just a few minutes after they left in and returns in their normal school uniforms. Anne returns the box to the Thrift shop and get an apology from Sasha and Marcy while the frogs, toads and Newts continue on with their lives. Anne hangs a new picture up on her room before she is called downstairs by her parents as Sasha and Marcy came over to give Anne a proper 13th Birthday. As Anne heads downstairs, the camera pans onto the picture which is the BFFs photo with the girls in their Amphibia outfits (Anne with leaves, Sasha with armor, and Marcy with armor). With the picture being the last screenshot, the credits come into play.

THE END.

Beautiful

I love that ending! Perfect way to redeem every character! But 2023 feels a bit too far away. The production of 1 whole season takes a year and around 2 months. The series gets a season 3, which is currently in production. Season 3 will probably be completed in August 2021. If Amphibia doesn't get a 4th season, then I believe there is no way of the series ending in 2023, but rather in 2022.

Yes, I agree.

I would like that.

Now for a spin-off series of Amphibia.

How I believe season 3 of amphibia will end WARNING SPOILERS FOR S3 and slight death

Annes attempts to find away back to amphibia seem sort of pointless after finding out about the coming invasion for her sakes, she knows she must get the planters home but is it even home at the moment? To be safe Anne keeps the planters in LA in the mean time while Darcy and Andries are only hours from heading to earth, But before this they must head to ask for willing participants in the battle especially the strength from Sasha… Darcy, stands their holding the box with a half of the fleat for the invasion. Sasha with a rush of energy runs twords Darcy with her dual blades, knocking into Darcy with an annoyed face. Darcy opens the box and ZAP! all goes black Sasha is teleported back to earth,…”Oh shit” meanwhile Darcy and Andreas prepare for battle while Sasha in the back ally way near the thrift store runs as fast at possible to Annes house in order to warn her of Andreas invasion only hours away. With fear Anne the planter and Sasha get prepared as quickly drones start pouring from the sky multiple in line Anne quickly worry’s and runs out of the house/they go to downtown LA// their they watch in aw as Andreas in armor walks down a flight of stares with a grimis smile and behind him a black figure apears with black horns and 10 glowing eyes// Darcy…..Anne staring in confusion mixed with a tad bit of disbelief looks to the side to see Sasha crying attempting to hold back tears…. “Anne I think that’s Marcy…” anne sparwles upwards “no…no.. that can’t be mar mar..” eyes start to fill up with tears as her hair glows blue “ Hello Andreas I’m sorry but you choose the wrong day to come here the wrong person to mess with” with an angry tone Darcy steps out and softly brushes Annes chin “Oh hello Wit haha missing your friend are you? Yes this human is quite pathetic crying and well she’s an equal part of me.. she’s allowed us to be like this” anne went to her knees still in disbelief as Sasha started fighting of the drones.

So to summarize the ending

Darcy backstabs Andreas sending him captured in a fleet of robots and attempts to kill Anne and Sasha saying that Andreas was to pathetic and weak to get the job done. As Darcy and Anne battle darcy gets Anne to the ground holding a sword near her face, Sasha runs from behind darcy scling off an gill from the helmet this cracking part of the mask “UGHH the core groans clasping their face Why did you do that stupid human” the crew look in an aw as half of Marcys face lays revealed but her eye is orenge and yellow. HAHAHA the core reminiscing you thought it was that easy?” Then Anne gets pushed down to the ground and Darcy stabs her “Anne crying blue power from her hair retreating collapsing to the ground..” Sasha runs over “ ANNE!!” Anne says softly “I can’t keep awake.. it’s up to you and the planters.. please keep them safe for me” Sasha with tears in her eyes heads to Darcy and says “ Mar mar I know you’re still in their.. I might not be wit I may not be heart but I’m strength maybe that means I help motivate people keep the group strengthen I haven’t done a good job with that and I’m so sorry. It’s not your fault and I..Anne and I forgive you and love you and miss you and…and” crying Sasha drops the swords. Darcy stands their not saying anything when all of a sudden her eyes revert to brown “Sasha… faintly Marcy says” Sasha screams “ MAR MAR? In an instant Marcy throws off the helmet and runs twords Anne “ANNE NO NO IM SO SO SORRY” tears welling up. Marcy is all scratched and hurt so Sasha holds her back, Marcy calls off the robots and Andreas still being trapped gets put into the dungeon not ever being able to rule amphibia again.. Anne and Sasha hug Anne and then Annes heart started pumping but blue light coming from her chest and instantly wakes up. “I’m awake??” They all hug each other and take the box back to amphibia to say goodbye to the planters in the meantime and everyone else vows to work to keep amphibia safe and rebuild. Olivia becomes queen while grime becomes the head officer to the queen of guard as they help to rebuild Newtopia. The girls holding the box head home taking the box with them to make sure that no one ever gets it in their hands. They stop at every house and great the parents with tears. As they all meet together shortly after and celebrate Annes 13th birthday they end with a hug and then run out side use the box and be transferred back to amphibia, they have some fun run around fly with joe and vist some other worlds then return… and that’s the end
