Pokemon, Yoshi's Island, and The Legendary Starfy put into a blender. When it comes out, it's a clean action/adventure platformer with hints of RPG thrown in there (EXP, Lvs, moves, items, random encounters, healing stations). Boss fights will end if one Trainer defeats the other, but battles go on even after all Pokemon on one side have bought the farm. The only downside to having all your Mons dead is that you'll get fewer points and less money. It takes place in the Kalos Region, and you play as Yoshi, who's trying to save it from the evil clutches of Team Flare. You're given two Zygarde Cores right away, and you have to find 100 Zygarde Cells scattered across the region. What makes this unique is that the Terrible Trio will also be making an appearance. And by an appearance, I mean they're the bad guys pretty much throughout the entire main game. Pufftop also becomes available, but it's mostly bonus sections. There are a few story-centric parts of it, like at one point, where Snips is knocked off the Flare Frigate while trying to use a Rainbow Droplet's power to give you a free ticket to Heaven, and you have to find another one to cure her broken legs. If you beat the game and even just one Cell is missing, the bad ending will play: Yoshi and his plucky Pokemon partners celebrate saving Kalos from Team Flare, but one lone male Grunt stands way in the corner, holding a Zygarde Cell hostage. The good ending will only play if you locate all 100 Cells, after you defeat the Pseudo-Final Boss, Lysandre. What happens after that is that Yoshi and co will celebrate like normal, but instead of that Flare Grunt holding a Cell hostage, the Grunt will call out the Trio mid-celebration for being so Janken-themed. Then, the three will quit Team Flare on the spot, reverting to the color scheme they had before they joined, and then, they'll rush off to Route kl6. This begins a new part of the game where you have to run after the Trio, them just disappearing off each new screen you enter the closer you get to there. Once you actually reach Palais Road, you'll hear a BOOOOM noise, and the sky will turn brown. You investigate the sudden kaboom, and you find out that Parfum Palace is actually a mile in the sky now. You have to get up there somehow, by using the now non-hostile wild Pokemon (you know, the ones you've been killing with a bunch of your OWN Pokemon for EXP) for leverage. If you wanted to use your OWN Pokemon for leverage, remember that flying works like Tails's flight ability, in that it only lasts for about 20 seconds before you tire out and descend quicker and quicker. The Pidgeys fly a bit faster than the Fletchlings, so plan ahead a bit. Several hundred frustrating jumps later, you find that Parfum Palace has been converted into a huge, five-story palace, with the trials on the middle three floors. The Rock-Paper-Scissors motif continues throughout all of them. The first trial is centered on Papes and involves a tight network of tunnels you can't Intangibilize your way out of. The second trial is centered on Ronk and is about shifting platforms over which you can't fly. The third trial is centered on Snips and is made of tons of sharp weaponry that's immune to psychokinesis. In short, Dungeon Bypass is inverted because it's against the rules. Meaning you can't use your precious Pokemon. Unless you like using a Rapidash to zip across the castle. Once you FINALLY make it to floor number 5, you're ready to square off against the Terrible Trio themselves. They each have a Wormadam (one for each cloak), and each Wormadam is equipped with a move of her secondary type (Grass = Leaf Storm, Ground = Earthquake, Steel = Gyro Ball). When you defeat them (which WILL take a while, as they're some of the hardest bosses in the game), there's a special cutscene that will trigger: The Trio, realizing that even together, they're still unable to win, actually FUSE TOGETHER just to put themselves (or rather, herself) at an advantage. That's when 100% Zygarde will finally show up and you get to PLAY AS HIM. He can do crap like firing lazers, causing earthquakes, and to put the icing on the cake, HE CAN FLY. He's fighting against Perfect Janken, who's many times smaller, yet just as powerful. To put it into perspective, this is like the Tirek v.s Twilight fight in Twilight's Kingdom, only with the roles swapped. Then, once you defeat her, a very special cutscene plays where she explodes into shockwaves, the whole world around 100% Zygarde will blossom into a bunch of beautiful flowers, and the sky will now turn bright blue. If you manage to complete the game like this, a flower will appear on the title screen. Also, you'll get a boss rush mode, a sound test, and a minigame mode where there are 8 minigames based on the 8 main-story worlds in The Legendary Starfy.
