"18-year-old Ben Tennyson is transported to the magical world of Earthland. Upon arrival, he immediately engages with the Fairy Tail guild. With a few hiccups along the way, while adapting to Earthland and his situation, Ben finds himself with trouble understanding how to get home. With aid from his new teammates, he learns to make a new life and undergo adventures to help him realize there was more to life than the one universe he thrived in."
In October 2020, Ulltimate10 abandoned the fic (and writing altogether to pursue new goals) but it was adopted by TypingMonkey98 with Ultimate10's approval. The original can be found here while TypingMonkey98's version can be found here. Oh, and the fic has its own wiki, believe it or not, found here.
Ultimate Fairy provides examples of:
- Adapted Out: The events of Ben 10: Omniverse did not happen, though aliens introduced in Omniverse still appear.
- Age Lift: The fic begins two years after the end of Ultimate Alien, meaning Ben is 18-years-old.
- Baleful Polymorph: In one chapter, the Omnitrix malfunctions traps Ben as The Worst after transforming Natsu, Lucy, Gray, Happy and Elfman into Cannonbolt, Upchuck, Crashhopper, Rath and Fourarms versions of themselves respectively. To make matters worse, three thugs, The Rabid Weasels, are transformed into NRG, Armadrillo and Humongousaur.
- Composite Character: Ben takes ques from several different points in his life. His character is primarily based on his canon counterpart in the first two seasons of Alien Force with the same outfit. He has the new Omnitrix he received at the end of Ultimate Alien, and it also has the evolutionary function from the same series.
- Commonality Connection:
- Heatblast becomes Natsu's favourite alien because they both have fire powers.
- Likewise, Big Chill becomes Gray's as they both have ice powers.
- Happy, perhaps unsurprisingly, becomes a fan cat for Rath.
- Elfman bonds with Ben because their both shape shifters, even asking Omnitrix wielder to give him some pointers.
- Fusion Dance: Upgrade merges with and enhances Erza's armour. This leads Upgrade to becoming Erza's favourite of Ben's transformations.
- Official Couple: Ben and Erza.
- Original Character:
- Beelzebash, the Omnitrax's sample of the Galuna Island demons.
- In Chapter 41 Ben unlocks the sample from the map maker dragon's species seen in Alien Force, which he dubs Laserscale.
- Vanessa Masters.
- "Reason You Suck" Speech/What the Hell, Hero?:
- Ben gives a brutal but deserved one to the Allied Forces, including his teammates and Wizard Saint Jura, after they didn't take the threat of the Oracion Seis seriosuly and let their pride and petty rivalries to get the in the way, leading to Erza getting poisoned and Wendy captured.
