One day, Infinite led his squad on a raid of Dr. Eggman's base in the Arsenal Pyramid in an attempt to steal his devices for a hefty bounty. Using the Phantom Ruby, Eggman created an army of Egg Pawn Phantom Copies to fend off the Jackal Squad. Slipping past the Egg Pawns, the ultimate mercenary ordered his squad to handle the robots while he moved in to kill Eggman with his sword. However, Infinite accidentally struck the Phantom Ruby instead, causing it to show him an illusion of what he desired the most: a desolate, destroyed world. Using this to push Infinite aside, Eggman, who also saw the vision, took a liking to him and offered to make him the leader of his Eggman Army so they could accomplish their goals together.

Some time later, Infinite and the Jackal Squad got assigned by Eggman to guard his facility in Mystic Jungle. When Shadow the Hedgehog came to raid and destroy the facility however, the Jackal Squad were easily annihilated by the hedgehog

Silence. Everyone on the lookout, on edge, weapons pointed straight out, trained and ready for anything. Suddenly, chaos! Machine gunfire, exploding bombs, ringing in their ears, confusion.

Cardinal piloted a mech big and imposing surely with his training he could operate such wonder and take the enemy down but just as easily as lighting a firecracker it blew up with him still inside a gonner

Chaos all around him, Infinite advances alone.

Dr. Eggman:
Over radio
Hey, you! I know you can hear me! You're captain of Squad Jackal, aren't you?! Your squad was useless! Go clean up their mess already!

Infinite:
Yeah, yeah, I got it...

So he stood to face over shadow Lupulella mesomela y Paraechinus hypomelas he glared at him with furry held back by mercenary training. In less than a day they were all gone, and he would not let such transgression slide he would either avenge their death... or die trying.

How... how could you do this to my men?!
I'll show you why they call me the ultimate mercenary! Take

Charges at Shadow
THIS!

Shadow activates Chaos Control.

Infinite: What?!

Shadow attacks Infinite with a roundhouse kick, launching the jackal in the air, and slams him down with his two fists, making him fall to the ground. Shadow delivers the final blow to Infinite with another roundhouse kick, launching him into another stone pillar, where Infinite can be heard groaning as he struggles to get up from getting easily thrashed by Shadow and his chaos powers. as with ease shadow crushed him to the ground badly scareing and wounding him but while infinite was waiting for the release of death to at least have the honor of falling with his brothers and seeing them again in the afterlife he did not get that
shadow simply looked at him scoffed.

Shadow:
He Steps on top of a nearby stone, looking down at Infinite
Worthless. Don't show your pathetic face around me ever again.

The camera cuts to Infinite's point of view as Shadow teleports away to continue his mission. As Infinite was alone, on the ground, in pain, shaking with his arm over his eye feeling the boiling liquid of life fall from his face as he was left to live with his comrades' blood on his hands knowing he couldn't do anything to stop it.
he felt worthless, pathetic, weak...

[INFINITE]
This isn't happening
Inútil, useless
Just like my father was before me
Inútil, useless

And every day, he cut the cane
He came home late and prayed for rain
Prayed for rain
And on the days when nothing came
My father's face was lined with shame
He'd sit me down beside him and he'd say
"My father was a farmer
His father was a farmer
And you will be a farmer"

But I told him, "Papi, I'm sorry, I'm going farther
I'm getting on a plane
And I am gonna change the world someday"

And he slapped my face
He stood there, staring at me, useless...
Today, my family's gone and I am useless
…

but he would not accept that, he would not stand by he was not weak! HE WASENT he would get stronger, he would get his revenge and with nothing left in the world he'd bring it down to if he had to.

I will not be the reason
That my family can't succeed
I will do what it takes!
They'll have everything they need!
all my work! ALL MY LIFE!
EVERYTHING I'VE SACRIFICED WON'T HAVE BEEN USELESS!
