Undertale Tickle Stories (Main Series)

W.D. Gaster, the Best Uncle Ever Part 2 (Chapter 3)

The next level of virtual reality is here thanks to Gaster! :D With the capabilities of his special chamber (simulation chamber, hologram room, VR room, etc. whatever you want to call it), he was able to create a highly immersive fantasy-themed role-playing game for the kids to all play together. And while this game of Gaster's appears to be coming to a close, the fun that he and the kids are all having certainly doesn't have to end after said game is over. No siree! ;)

W.D. GASTER, THE BEST "UNCLE" EVER PART 2

Chapter 3: "Endgame"

Frisk, Chara, Asriel, and MK have all had a great deal of fun playing Gaster's game thus far. From Elmore and Terisa's castle all the way to the barbarian village, there wasn't a single dull moment. How could there be with a room capable of creating such immersive environments? But their adventure wasn't over yet. To complete their adventure, they needed to fight the evil sorcerer, Tesgar. And after devising a strategy with their new allies and the in-game versions of their real-life family members and friends, that's exactly what they did. And reaching Tesgar was no easy task. Because outside of his castle was an army of shape-shifting crystal creatures, the strongest enemies in the entire game besides Tesgar himself. If the kids had faced them on their own, they likely wouldn't have made it past the first barrier. So that's why they enlisted the help of basically every good-aligned character they encountered in the game up until that point, including the in-game versions of their real-life family members and friends. Only with an army of their very own would they stand a chance against Tesgar's crystal creatures; every single one of them, including a crystalline dragon they fought just before entering Tesgar's castle! It was Tesgar's loyal pet and boy was it tough to take down, tougher than every enemy the kids encountered up until that point! They needed all the help they could get to destroy this dragon. And they destroyed it, but it cost them another use of the Sorcerer Gaster spell. That time it was casted by MK, the third kid to make use of the spell in the game. With Asriel, Chara, and MK's uses of the spell gone, Frisk was then the only kid capable of using the spell before the game's end. And she used it, but not until first fighting her way through Tesgar's castle itself. In order to reach Tesgar himself in the highest room of his castle, the kids first needed to battle their way through corridors of more crystal creatures. The final stretch! And one that wasn't too terribly difficult due to the assistance of their new allies (including the in-game versions of their family and friends). With help from their new allies, the kids pushed their way through Tesgar's castle until finally reaching Tesgar himself in his crystalline lair. And they weren't alone when they reached him either! Just before Tesgar (who appeared as a tall crystalline man with crystal skin that repeatedly changed its color, a white sorcerer's cloak, and no visible face when he was first encountered) sealed off the entrance to his lair, Cleric Toriel, Barbarian Asgore, Monk Sans, Warlock Papyrus, Paladin Undyne, Wizard Alphys, Ranger Blooky, Bard Mettaton, and Druid Muffet entered to assist the kids in battle. Thirteen against one! And the nine adults' assistance was more than needed against Tesgar himself, for he was a very powerful sorcerer with an onslaught of magical powers! There were three phases to Tesgar's battle. And of the three phases, Phase 1 was by far the easiest. It wasn't easy by any means but easy compared to the final two phases because it simply involved fighting Tesgar with only a fraction of his abilities (conjuring weapons and crystal skulls that shoot energy beams and using telekinesis). Pretty basic... at least until the thirteen warriors rid him of his cloak at the end of the phase (his cloak provided him a layer of protection). Once he lost his white sorcerer's cloak, Phase 2 began, and he became far more aggressive as a result; frequently teleporting and spawning various crystal spikes out of his crystalline body as well as the crystalline floor underneath him. And out of thin air as well! And if that wasn't enough, he was also creating clones of himself! He was truly a force to be reckoned with in combat. Difficult to defeat, yes... but not impossible to defeat. And with careful planning and teamwork, the thirteen warriors eventually managed to subdue the evil sorcerer himself, overwhelming him to the point of breaking his crystalline exterior. And because they had broken his crystalline exterior, they were given the impression that they had destroyed him once and for all, only to find out that he was still alive and more terrifying than ever! Because underneath Tesgar's crystalline exterior was his true form, a grotesque demonic creature with bulged eyes, crooked teeth, a flaming head, and a body covered with moving red-orange tissue and countless red, blue, and purple tendrils! And as Tesgar's appearance changed so did the appearance of his lair. In an instant, everything that was once made of crystal changed to fire and brimstone, indicating that the third and final phase was about to begin. And it was the toughest of the three phases, that's for sure, every single one of Tesgar's attacks gaining hellish upgrades. But the thirteen warriors had an edge though. And that edge was one final use of the Sorcerer Gaster spell. Frisk had not yet used it. Feeling that there would be more than two phases to Tesgar's fight, Frisk saved it and used it during the third and final phase. And she only used it when it was absolutely necessary, to save the lives of those that had been greatly weakened by Tesgar himself from an onslaught of killing blows. And although Gaster didn't destroy Tesgar once he was summoned, he did distract the demonic creature enough for the kids and in-game versions of Toriel, Asgore, and seven monsters that are like older siblings to the four of them to hit him with everything they had, destroying him once and for all in the process. With Tesgar destroyed, peace was completely restored to all of the areas of the land. And with peace completely restored, that meant that the kids' adventure had reached its end. And what an adventure it was too! From start to finish, the kids had one hell of a fun time! Even if there was no tickling whatsoever at any point during their adventure. After all of the tickling shenanigans that had happened prior to playing Gaster's game, the kids thought for sure that Gaster would've included an encounter with some kind of tickle monster. But the game wasn't over just yet! Sure, the kids had defeated the evil sorcerer, Tesgar, but they hadn't yet traveled back to Elmore and Terisa's castle to celebrate their victory. It wouldn't have surprised the kids one bit if someone (or something) was waiting for them back at Elmore and Terisa's castle to tickle them as a means of thanking them for all of their heroic deeds throughout the entirety of their adventure, like Asriel's beloved Elisa and/or MK's beloved Mona or even King Elmore and Queen Terisa themselves! ;) But the kids wouldn't know for sure until first taking some time to eat some supper in the dining room of Gaster's subbasement. Gaster's game went on for several hours and by the time the kids defeated Tesgar, it was 7:30pm! And Gaster for one wasn't going to let the kids go one more minute without eating any supper! So, once the game's main antagonist had finally been defeated, Gaster then changed the room back to its default red and black appearance as well as the kids and himself back into their normal attire, to indicate to the kids that playtime was over. For the time being, at least. Then not long afterwards, Gaster and the kids exited the room to eat a late supper together in the dining room of the subbasement. And just like the breakfast and lunches they had earlier during the day, it was another wholesome meal, which was good because fighting an onslaught of holographic beings really worked up an appetite! They even had room for their second slices of black forest cake! Then after eating supper, the four kids and Gaster rested for a few minutes, to let their stomachs ("stomach" in Gaster's case) settle after eating such a wholesome meal. And just as Gaster did after he and the kids ate lunch together earlier during the day, he let the kids take turns sitting on his lap; first Chara, then Frisk, then Asriel, and then MK. Only this time, he didn't get too relaxed while doing so. This time, he watched all four kids like a hawk, just in case one or more of them tried to tickle him again while they were relaxing. There was no way in hell he was going to let them catch him off guard a second time! And certainly not before telling them why MK's lightning had no effect on him at that time they had successfully caught him off guard!
