Anti-Magic: His Level 2 ability reverses the process of any ability.
Awesome by Analysis: So much that once he's figured out your powers and how they work, it is pretty much an Instant-Win Condition of Ueki; from that point in the fight onwards its only a matter of time before he beats your face in.
Made of Iron: Which causes Robert to undergo a Villainous Breakdown.
Missing Mom: It turns out that she's dead. That's his human adopted mom.
Played straight with his real Celestial mom who's implied to have left his real dad after he was dropped off in the real world.
Multi-Melee Master: Most Celestial Beings can only summon one Sacred Weapon at a time. Ueki's level 2 Celestial power (not his regular level 2 ability) allows him to summon more than one or all of them at once.
No Sense of Direction: In the fight against Marilyn's team, he couldn't figure out where his teammates were and ended up in other places in that area until he backtracked to where he beat one of his opponents, took the scanner from him and used it to find his friends.
Your Days Are Numbered: He has the fewest talents in the series for some odd reason and as a result, the more he hurts outsiders, the more talents he loses. Once his talents reaches, zero, he'll die. Mori has to keep reminding him not to use his powers but he doesn't listen.
Badass Normal: For half of the series before she got her powers, she was able to hold her own in battle by outsmarting many of the villains. Even with her useless power, she managed to trick them and still come off on top.
He Who Must Not Be Seen: Her parents almost never appear in the anime but they make at a few cameos in the manga as they often worry about their daughter.
Lethal Chef: Subverted. Her food looks bad but tastes great.
The Load: A more straight example than Hideyoshi. She has useless powers that can't help her friends out. Becomes more evident in the final battle in which all she can do is stand there and watch Anom kicked the crap out of Sano and Rinko.
Break the Cutie: Karlpaccho tried this on Sano by threatening to kill his God Candidate Inugami that he probably saw as more than a friend by planting a bomb on his neck and if he didn't join his team, he would set it off. He then forces Sano to fight against his friends. While Sano was trying to go around the deal by pretending to lose to Kosuke, Capucho wouldn't fall for it and then puts Mori and Rinko's life on the name as well as Inugami. It's when Inugami sacrifices himself to give Mori her powers and goes to Hell as a result is when he finally breaks down. Capucho then pushes his buttons by calling his friend a loser for forfeiting his chance to become God for someone like him. And while Kosuke stands up for him and demands to fight Capucho to take back what he said, Capucho declares that Sano won the match because Kosuke finish him off and then forces Sano to watch from the audience stand as he beats up Kosuke quite a bit. At this point, it becomes obvious that this tactic worked but Sano quickly grows out of it.
Distressed Dude: Subverted. Kosuke assumes he's this when Inumaru claims about Robert capturing Sano but Sano clearly states he joined Robert's crew on his own free will. He still needs to get out of the jam of course.
Parental Abandonment / Parental Neglect: This is the case for Sano's family since Sano never mentions his parents nor do they get screen time. The way he treats Wanko is more like a father than a friend and then there's the fact that Sano actually doesn't live where the series take place and in the sequel, he seems to be out of the country BY HIMSELF.
Screw This, I'm Outta Here!: During the last battle, he abandons his friends because he knows he can't beat Anon. He comes back near the end because he realized he wouldn't be able to forgive himself if his friends died. This causes him to get knocked out by one of Kosuke's attacks and sure enough, saves his life.
Ventriloquism: His ability is to turn voices into portraits. By undoing the power, the portraits turn back into voices, allowing him to make his voice come from different locations. He's especially good at using it to surprise, distract, or misdirect his opponents.
Cast from Lifespan: His ability to make ideals real cuts off a year of his life per ideal used. The primary function of Robert's Ten is to do all the fighting for him so he doesn't have to use the remaining years of his life to fight.
Heel Realization: He realized that life is not fair after his basketball team was disqualified for the Nationals for taking revenge against their last opponent who dealt a No-Holds-Barred Beatdown on their ace player.
