Beware My Stinger Tail: Tails' namesakes are quite versatile in this story and form the center of his combat abilities.
Big Eater: Taken to Running Gag levels as he regularly stuffs himself whenever he can shovel food into his mouth. Carth Onasi lampshades this when he asks, "Were you chronically starved on your planet?!?"
Break the Cutie: Tails begins to suffer this as he experiences the death and destruction around him.
Can't Catch Up: How Tails compares himself to his friends and allies back on Mobius, much to his frustration. It's what lead him to install the cybernetic augmentations in his body
Cartoony Tail: Two of them, of course. In this story, now that he's a teenager, they've grown to twice the length of his own body. (the page image doesn't quite capture that...)
Chick Magnet: Chapter 005 describes in great detail what adolescence has done to Tails' body. While still short and wiry by Human standards, Tails is now much taller and more muscular than before. Think 'highly athletic teenager' and you're on the right track. Tails gets hit on by multiple characters, much to his confusion and embarrassment.
Chronic Hero Syndrome: Tails' perennial MO, with him even referring to the trope by name. It very nearly gets him killed, and Carth Onasi calls him out on it during a Timed Mission.
Cruel Mercy: Tails planned to defeat Bendak, keep him alive, and have him go to jail for the rest of his life. Bendak instead decides to pull a Taking You with Me and pulls out a grenade...
Cyborg: Tails is one, by his own choice. He has reinforced bones, organ function monitors/regulators, nanomachines, and a secondary neural network.
Evil Is Not a Toy: Tails thinks back to several occasions where Robotnik tried to control forces beyond his ken and failed, like Perfect Chaos, Tabuu and Dark Gaia.
Extreme Omnivore: Tails. Justified due to the fact that he has abnormally strong stomach acid, cybernetic implants in his digestive system, and gut flora he genetically engineered. He does however have some issues with too much starch and sugar, and can't really eat chocolate due to the risk of theobromine poisoning.
Half-Dressed Cartoon Animal: Mobians view the hands and feet as the most private parts of the body, and thus covering them is a top priority, everything else being a matter of personal preference. Tails has to subvert this by wearing clothes though.
Hammerspace: Used and discussed by Tails, much to Carth's bewilderment. Tails basically carries a portable pocket dimension in his tails, and he even calls itHyperspace Inventory (though he did call it Hammerspace at one time due to Amy's pulling her Piko Piko Hammer out of her pocket dimension)! Carth Onasi eventually dubs it "tailspace". Apparently time moves slower in it.
Heli Critter: Of course. In here, Tails has two flight modes: his general-purpose 'helicopter mode' that has great versatility and a top speed of about 200 MPH, and a much faster and energy-intensive 'turbofan mode' (similar to a jet engine) that can propel him up to 600 MPH or higher. Carth lampshades how absurd this is when Tails carries him down to the Undercity.
Nightmare Sequence: Several, but a particularly trippy one in Chapter 038 symbolizes his insecurities and his separation from his childhood friends.
Omnidisciplinary Scientist: When Tails was on Earth he was awarded eleven Ph Ds and eight masterís degrees in the fields of science, engineering, and mathematics, with some minoring in biotechnology and cybernetics.
One-Hit-Point Wonder: Averted for Tails in this series; he takes damage like anyone else does. He starts pining for Power Rings as his injuries start piling up, though.
Power Creep, Power Seep: Tails is much stronger and tougher here than is implied in the games or other media he regularly features in, though this is justified due to both him being older and him making himself a Cyborg.
Scars Are Forever: Tails' body is a circuit board of old bullet wounds and lacerations, and he knows them all by "date, opponent, and serial number". To him, his scars are much like the medals pinned to a soldier's uniform. Unlike Sonic, who can perform suicidally stupid stunts and escape mostly unscathed, Tails has to work for his heroism.
Schedule Slip: While there was never any regular schedule (it started out weekly and rapidly degraded from there), the author went from February 2011 to April 2013 without an update because of real-life woes. The updates have been picking up lately.
Steel Eardrums: Played with. In Tails' death duel with Bendak in Chapter 043, the boy notes how grenade explosions were greatly muffled in previous duels because of the arena's energy suppressors. With them off, grenades would be much more powerful and deadly — and LOUD. Tails manages to weather several such explosion without too much damage, but then the sonic grenadescome out.
In Chapter 007, Carth tosses a pair of frag grenades to wipe out a pair of Sith and their droids. Tails suffers tinnitus temporarily, but apparently no one else does.
Taking You with Me: Tails wins his duel with Bendak without killing him, planning on having the duelist arrested. But when Tails refuses to kill him, Bendak detonates a grenade, killing himself, Tails only narrowly escapes.
Ungrateful Bitch: Bastila, who doesn't show much gratitude towards Tails and Carth's efforts to rescue her, to the point that Carth is obviously annoyed and Tails has to resist the urge to bitch-slap her, and when she finally admits that he did at least "help" in her escape, it's very grudgingly.
Wake-Up Call Boss: The rakghoul swarm of Chapter 029. Tails gets absolutely shredded.
What Measure Is a Mook?: After meeting Sarna, a junior officer with the Sith, Tails ponders the nature of this trope if he had to face her in battle. He even notes how, in her Sith armor, Sarna would be just another faceless mook and completely dehumanized.
