Ender

Ender immediately encounters the challenge of isolation during his arrival at Battle School.
His trainer, Colonel Graff, isolates him to avoid distractions and people that will disable him from relying on his own strength and intelligence.

Ender feeling isolated
"The fear stayed, all through dinner as no one sat by him in the mess hall. The other boys were talking about things – the big scoreboard on one wall, the food, the bigger kids. Ender could only watch in isolation." (page 73)"The fear stayed, all through dinner as no one sat by him in the mess hall. The other boys were talking about things – the big scoreboard on one wall, the food, the bigger kids. Ender could only watch in isolation." (page 73)

Due to Ender's persistence, he attempts to create allies and build friendships continuously, successfully displaying his persistent personality.
In the event when Ender joins a new group full of older kids who despise him, he persists and finds a way to train and learn the skills he needs to be successful.

Ender overcoming this challenge through his persistence and making friends
"They [Shen and Ender] laughed together, and two other launchies joined them. Ender's isolation was over." (page 86)

Ender is very intelligent, especially for his age.

Ender's intelligence
"He always knew the answer even when she thought he wasn't paying attention." (page 35)

I can connect to this to a show called Naruto. even
though one kid in the class never pays attention
(Sasuke) he always knows the answer to every
question. so the teachers try to pick on him when
hes not paying attention. They always pick him to
answer the question but he always gets it right just
like Ender.

He is able to understand, learn and perform quicker than the other children at Battle School.
Ender advances in Battle School faster than the average student, leading an army of his own at the age of 10.

"All he had to do was watch the game and understand how things worked, and then he could use the system, and even excel." (page 80)

Ender manages to work with a new team when his teacher transfers him to Salamander Army. Even if he is seen as a competition by the team, especially its leader Bonzo, because of his strong capabilities as a launchy, he is still able to adapt to his discouraging team.

When he joins the Salamander army, he quickly adapts to Bonzo's rules and the unpleasant surrounding.
"Since Bonzo had ordered him not to draw his weapon, Ender continued to drift, not moving his head or arms, as if they had been frozen too." (page 125)

As an inexperienced and young member of the Battle School, Ender effectively adapts to being a leader when he is promoted to lead an army of his own.

Ender's adaptability to become a successful leader, despite the fact that he's very young and Colonel Graff exhausts his army by putting them in multiple battles almost every day
"At the end of the week Dragon Army had fought seven battles in seven days. The score stood 7 wins and 0 losses." (page 224)

When Ender enters the zero gravity Battle Room for the first time, he immediately finds a way to learn which tactics will work best to stabilize him.

Ender "found himself ripping the seat tightly, even though gravity pulled him firmly against it. The other boys were bouncing on their seats a little. Ender carefully found the straps, figured out how they fit together to hold him at crotch, waist and shoulders." (page 61)

I can connect this too my daily life in a car because
when you are in a car and the driver makes the quick
turn everyone in the car start leaning to the side and
start bouncing on the seat even if they have a seat
belt on but I'm the only one who doesn't because I
always hold on to my seat belt or the seat in front
of me so I don't lean or bounce around.

He discovers efficient ways to beat their enemies, and successfully creates formations that will not only lead to their victory, but also the less numbers of attacked members.

"... and this time, Ender was deft enough to pull off a few maneuvers that the boy had obviously never seen before." (page 80)

I can connect to this with my soccer skills because
Ender found new ways to beat his enemies by trying
new skills and not just charging in just like how when
the other team is charging at me and i kick the ball
over so i can get past them because if i just ran at
them with the ball they might have gotten it.
