Players introduced in the Tournament
- Position: Quarterback and Kicker
The only decent player for the bottom-of-the-barrel Cupids. Mainly known for having a hot girlfriend despite being smug and unattractive.
- Book-Ends: The first and last opponents Sena faces in the entire series.
- Butt-Monkey: His only role in the story, even during the epilogue.
- Establishing Character Moment: Mocking other players for not having a girlfriend. Become his principal trait.
- Jerkass: Really smug about having a girlfiend and being somewhat good at making kicks.
- Laser-Guided Karma: His attempt at flaunting how his teams have girlfriends cheering for them always take a turn for the worst.
- Master of None: Hatsujou is his team's ace, being probably the best player they have, or at least capable, at every single role. Considering which team he's captain of, this isn't saying much.
- Mr. Exposition: To his girlfriend during Deimon's match with Taiyou. Explaining what a sack a kick conversion is.
- Smug Snake: He talks big but he really can't back it up.
- Ugly Guy, Hot Wife: Has a very hot girlfriend while he, even if not particularly ugly, is far from being a pretty boy.
- Position: Linebacker
Captain and only dedicated player of the Zokugaku Chameleons, Rui is a delinquent who appears to be "threatening" in order to motivate his team. Grudgingly respects Hiruma and occasionally helps out the Devilbats.
- Animal Motif: Chameleon, obviously.
- Anti-Hero: Becomes this as the series goes on, especially during the World Cup arc.
- Badass Biker: Whatever you might think about his badassery as a football player, he's one hell of a Badass Driver on his bike.
- Badass Longcoat: A large white one that makes his arms even longer.
- Butt-Monkey: He becomes this whenever Hiruma is around.
- Can't Catch Up: He is a decent linebacker (one of the top three picked for the top 11 lineup at the end of the Tokyo tournament in fact, alongside Shin and Kakei) and was good enough to qualified for Japan team during world cup but he is no top tier player.
- Cool Bike: In a bonus material he pulls all sort of stunts when people comments how cool his bike is.
- Defeat Means Friendship: Though originally it was more like "defeats means slavery".
- Delinquents: His entire team is made of these.
- Determinator: He's definitely one. Too bad the rest of his team isn't. He got swat away by american players but still goes even if it's humiliating and makes him look like a joke, because he does not care what people think if he can play. Also, the reason he's a first-string member of Team Japan is due to solely to hard work.
- Eviler Than Thou: Even one of the heroes is eviler than him...
- Knife Nut: To compliment Hiruma's trigger happy.
- Not So Different: With Hiruma, after Rui's defeat. Both used fear and terror to motivate their teams to play harder. The only difference between them is that while Hiruma was far worse than Rui, he had other kinder people with him to balance it out. Hiruma silently acknowledges this.
- Overly Long Tongue: As a chameleon.
- The Only One Allowed to Defeat You: Why he drove Sena to the Amino game.
- She Is Not My Girlfriend: Or so he says...
- Throw the Dog a Bone: He got recognized as one of Tokyo's best lineman during the Fall tournament and was chosen as a Team Japan first-string player.
- Took a Level in Badass: For the World Cup.
- You Are Better Than You Think You Are: Why he still trains the first years after his Christmas Bowl's dream is over he actually wants to make them more than two-bit thugs and shape them as a team.
The manager of the Chameleons and one of Rui's closest friends.
- Biker Babe: Being from Zokugaku.
- Corner of Woe: Played seriously after the Chameleons' loss to the Poisedons. She's shown standing around a corner looking deeply depressed while Rui breaks down after the game.
- Cute Sports Club Manager: She looks the part...than she opens her mouth.
- Drill Sergeant Nasty: She helps Rui force the other players to train harder.
- Even Evil Has Standards: Does not seem to approve of just how violent Rui can get.
- Groin Attack: Why she is so strong in battle and why she has a wooden katana.
- He Is Not My Boyfriend: With Rui, despite referring to him by his first name and everything.
- Iron Lady
- Single Woman Seeks Good Man: Appears to be attracted to Rui, not because he's a thug or a biker, but because he works very hard to improve his football skills, and because he tries to get others in the Chameleons motivated to do the same.
- Wooden Katanas Are Even Better: Never seen without one.
- Academic Athletes: Every one of them was supposed to be this.
- Curb-Stomp Battle: On the receiving end when they fought the Devil Bats. The main purpose of the Cyborgs' existence appeared to be to show how much the Devil Bats had improved after the Death March.
- Cyborgs: Their primary Motifs.
- Gonks: They somehow managed to assemble a full team of these.
- Joke Characters: Their status after losing to the Devil Bats.
- Muscles Are Meaningless/Science Is Useless: Played with. The Cyborgs built their muscles only through drugs and other forms of artificial stimulation, while the Devil Bats got theirs naturally through a very rough training regimen. The difference between these two could be compared to that between a body builder and a weight lifter: the body builder is more likely to grow bigger and more toned, but the weight lifter will end up having greater strength and stamina.
- Opposing Sports Team: Their method of training goes against every aesop in the series, though only Aoyanagi is a real jackass about it.
- Planet of Hats: A highschool full of robot-like Gonks who gained muscles through advanced medical science methods.
- Skilled, but Naïve: Being able to bulk up and come up with football tactics in one summer was an impressive feat. However, it was stupid to think that would be enough to defeat people who had practice and theory on their side. And that a running back wouldn't fix his obvious flaw.
- Smug Snakes: Munakata and Aoyanagi were both vocal about their supposed superiority, which made it funnier when the Devil Bats steamrollered them.
A buff, intellectual man who takes the idea of "brains over brawn" a little too far. Is almost always smiling and has a freakishly shiny face.
- Position: Linebacker
- Jersey: 29
- 40 yard dash: 5.3 seconds
- Bench Press: 115 kg
- 3rd Year Student (Grade 12)
- Academic Athlete: He's proud of it.
- Affably Evil: Off the field he's rather gentlemanly, and even on it he has a friendly charm that seems to be absolutely genuine.
- Arrogant Kung-Fu Guy: Did not hesitate to brag about his superior intelligence and training to Devil Bats.
- Boisterous Bruiser: Most of the time.
- Curb-Stomp Battle: He didn't even come close to touching Sena.
- Fan Disservice: Even his muscles are shiny.
- Fridge Horror: Invoked In-Universe. Just why do his parents look so alike!?
- Genius Bruiser: Him and everyone at Amino. According to him, those who graduate from Amino go on to either Amino Medical School or Tokyo University.
- G-Rated Drug: His ridiculously buff physique is thanks to "science". Right...
- Gonk: He kind of looks like a Ken doll on steroids.
- Hypocritical Humor: Gets angry when Americans underestimate Team Japan, then proceeds to bet on the American team as well.
- The Leader: The charismatic leader for the Amino Cyborgs.
- Muscles Are Meaningless: He's a buff guy... and Sena got past him effortlessly.Ikari: "Are those muscles just for show?"
- Stepford Smiler: If he's not smiling it means he's in serious trouble.
- Villainous BSoD: When he loses to the Devil Bats.
- Younger Than They Look: Lampshaded constantly. When the Devil Bats first met him, they assumed he was a doctor.
A geeky otaku who went from bony to bodybuilder in a year and a half thanks to, ahem, "vitamin supplements".
- Position: Lineman
- Jersey: 64
- Academic Athlete: The athletic part is a bit lacking though.
- Arrogant Kung-Fu Guy: Like Munakata, but without the jovial charm.
- Celebrity Resemblance: He used to looked exactly like Weird Al, complete with curls and geek glasses. After starting his training regimen, he looked like Weird Al on steroids. Like Yankovic, he's also incredibly geeky, but what stops him from being another weird Eyeshield football expy is that he's a jerk and a mild masochist.
- Evil Laugh: Fufufu.
- Gonk: Both before and after his unnatural training regimen.
- Jerkass: He seems to have a lot of issues left from his Geek Physique days.
- Jerk Jock: He's buff, and loves to taunt his opponent.
- Muscles Are Meaningless: His muscles are just for show, he doesn't have the stamina to use it properly.
- Straight Man: To Munakata's cheerful disposition.
- Too Kinky to Torture: Their manager can be quite cruel to the team and Aoyanagi loves it.
- Position: Quaterback
Captain of the Dokubari's Scorpion, he uses his ability to pick up football player habits to read the opponent plays. His technique allowed him to defeat 10 admittedly weak team. Admittedly weak turned out to be the operative word.
- Adaptational Villainy: He is smug in the manga but in the anime he is trying to get the other team disqualified or injured before the match.
- Awesome by Analysis: Parodied, he can see small habits such as quaterback licking their finger to indicate a pass but it doesn't do him any good against Hiruma who can read his opponent better than him and love confusing the other team. An Omake even has his father smacking him after he analyzed that he will smack him.
- Butt-Monkey: Worse than Amino, the match was pretty much Hiruma toying with him.
- Smug Snake: His reading of body language is really basic and Hiruma pointed out how it only work on teams that are garbage.
- Position: Line
An experienced, technical linemen who lost early on in the Tokyo tournament. Most well-known for being a talkative combat commentator whose predictions are never right.
- Butt-Monkey: Torakichi's butt monkey anyways.
- Combat Commentator: Parodied. Whenever he says something, the exact opposite instantly happens.
- Genius Bruiser: What he likes to think he is...
- Intergenerational Friendship: With Torakichi.
- Know-Nothing Know-It-All: As far as Torakichi's concerned.
- Odd Couple: He and Torakichi act as CombatCommentators.
- Overshadowed by Awesome: After he got smacked by The Worf Effect, Onihei was reduced to a Butt-Monkey so thoroughly that it's easy to forget that he is an exceptionally skilled player who gets singled out as an offensive lineman for the Tokyo top 11. This is emblematic of his team's problem in general actually; they focus on being really, really good at football's basics, but unfortunately for him this is a shounen series.
- Rated M for Manly: Was viewed as this during his introduction (he had "manly charisma") and many linemen were quite GAR for him until he became a victim of The Worf Effect.
- The Worf Effect: He was considered the most experienced lineman in the high school league, to the point that people were lining up for his autograph, in his first appearance. He gets defeated during his first onscreen game, and later doesn't even become a World Cup regular. (He does play as a second-stringer during the match against Russia)
- Younger Than They Look: He's only 18, but he looks like someone's dad.
- Wise Beyond Their Years: Subverted. He acts wise and experienced, but everything he says is always wrong.
- Wrong Genre Savvy: His knowledge is useless since all the players think outside the box.
- Jersey: 26
- Position: Running Back
- 40-yard dash: 4.6 seconds
The captain and ace of the Misaki Wolves, Kamiya is a long-legged, fast-moving player with a high opinion of himself. In the manga, his team was easily defeated by the Seibu Wild Gunmen; in the anime, he is a far more serious threat, and is only barely defeated, after giving Seibu's ace, Riku, a serious run for his money.
- Adaptational Badass: A joke in the manga, the anime turned him into a high-speed powerhouse, capable of matching Riku in terms of speed, and leading a team whom the Gunmen were only barely able to overcome.
- Animal Motifs: Wolf
- Arrogant Kung-Fu Guy: On the subject of speed. To be more specific, he's pretty smug about his speed due to his long legs.
- Cute Little Fangs
- I Am Not Left-Handed: In the anime, he says his recorded 40-yard dash time of 4.6 seconds is not his actual speed and says he is actually faster whenever he plays.
- You Gotta Have Blue Hair
Players introduced in the World Youth Cup
- Jersey: 54
- Position: Line
A middle school student from the Kansai area. He's a big fan of Sena and planned to enroll at Deimon High School after he graduates. Despite being a fan of Sena's runs and his small stature, he's a lineman because of his desire to protect Sena. His signature skill is called Delta Dynamite. He does become a member of the Devil Bats in the epilogue.
- Ascended Fanboy: He's a big fan of Sena and planned to join the Devil Bats after graduating from middle school. He gets to play with him sooner than he expected, and then ends up joining them after the World Cup.
- Badass Adorable: He's not only the youngest player in Team Japan, he's the only first-string member from Kansai who is not a Teikoku Alexander. He passed the Kansai tryouts by momentarily stopping and throwing Yamato off-balance.
- Crippling Overspecialization: He has nothing else other than his Delta Dynamite. On the other hand, that's all he needs.
- Curb-Stomp Battle: Delivers one to Rodchenko in the World Youth Cup.
- David vs. Goliath: His World Youth Cup debut was against the towering Russian Rodchenko. He repeatedly knocks him down despite being only half as short and not as buff.
- Epic Fail: His attempt at imitating the Devil Fourth Dimension.
- In-Series Nickname: Chuubou
- Signature Move: The Delta Dynamite. A blocking technique using the head, shoulder, and backfist, in a triangle position. This allows him to deliver an explosive amount of force.
- Weak, but Skilled: He's short, slow and weak, but his technique of using the Delta Dynamite allows him to overcome the toughest players.
- Jersey: 45
- 40-yard dash: 4.2 seconds
The captain of the German football team.
- The Ace: He's the best player of Team Germany. He's also the best player for the German team in Europe's Professional American Football league. And he's just 18 years old, and possibly younger.
- Awesomeness by Analysis: He memorized the stats of every player participating in the World Youth Cup, and used these stats to formulate strategies.
- Badass Bookworm: His idea of killing time is memorizing player stats.
- Curb Stomp Cushion: Mostly due to having the core of the Japan/German match offscreen. We see him stopping Sena once and the score is close but there was no doubt about the outcome of the game and was more of a warm up for Sena.
- The Leader: Of the German Youth World Cup team
- Photographic Memory: His greatest asset.
- The Quiet One
- The Stoic
- What Is This Feeling?: To him, American Football was just a game. It was only after he faced Sena that he realized how enjoyable it could be. He also did this to Sena because he was the first actual challenge he faced in the World Cup.
- Worthy Opponent: To Sena, a fact that both of them acknowledge. On a less personal note, his team serves as the first real challenge that the Japanese team encounters, a fact that Gaou and Sena both state aloud.
- Jersey: 67
- Position: Defensive Tackle
The Russian world record holder for the bench press and also an Olympic gold medalist for weightlifting. He started playing American Football and joined the World Youth Cup because of the 3 million dollar prize money.
- Curb-Stomp Battle: He becomes the recipient of this courtesy of Chuubou.
- The Dreaded: Team Japan's linemen were shocked at why he's even playing American Football, and with good reason too. However, he fails to live up to the hype.
- Jerk Jock: Easily dismisses Chuubou and calls him weak. He then gets on Chuubou's nerves by insulting Sena. Not a very good idea.
- Muscles Are Meaningless: He is an Olympic gold medalist weightlifter but too slow and inexperienced for national level football. While he ends up breaking Onihei and Juumonji's tactic with sheer muscle power Chuubou can toss him on his ass like he is nothing with a well timed strike and Gaou's Killing Intent combined with his strength can bitchslap him.
- Older Than He Looks: Some players even question whether or not he's within the age limit of 18.
- Only in It for the Money: The reason why he's participating in the World Youth Cup.
- Unskilled, but Strong: In pure upper body strength he should be the strongest in the series but he probably never played football or dealt with tackles until the World Cup. This gets him curb-stomped by Chuubou.
A team coming from the fictional country of Militaria. They crushed Team Finland in the 1st round of the World Youth Cup and seemed poised to do the same to Team Japan, having thought of them as a weak team. They get flattened during their match.
- Jersey: 26
- Position: Running Back
- 40-yard dash: 4.6 seconds
- Bench Press: 120 Kgs
The leader of Team Militaria
- Always Someone Better: His stats are actually pretty good so naturally, he thinks he's hot stuff. It gets funny when some members of Team Japan hears his stats and the best reaction they have is "meh". His bench press and dash record seems purposefully sub par to Shin just to show how harmless he is.
- Bald of Evil: He is a jerk and shaves everyone he can get his hand on's head as part of his military attitude.
- Curb-Stomp Battle: Delivers one to Team Finland. Unfortunately for him, he gets flattened by both Agon and Gaou during their match.
- No Indoor Voice: He's always shouting.
- Signature Move: The "Missile Run". Unfortunately for him, he's up against Agon, who easily swats him like the trash that he is.
- Smug Snake: Talked a big game against Japan and personally insulted Agon and Gaou. He can't back it up.
- Too Dumb to Live: He thought it was a good idea to shave Agon's dreads.
- Jersey: 06
- Position: Quarterback
Gomery's sidekick and quarterback for Team Militaria
- Curb-Stomp Battle: Suffers this along with the rest of the team.
- Smug Snake: Snickers at Japan's short point difference against Russia, if he bothered doing his research like Schultz he would have noticed that those aren't the starting players.
- Underestimating Badassery: After watching the Japan vs Russia match, he concluded that Team Japan was nothing to write home about. He fails to consider that the team that he saw playing was the second-string players with the exception of Chuubou.
