After the creation of Invader Blade and he having successfully training, Kex decided to create more irken super soldiers. Kex decided to use only military grade irken gene stock to create this super soldiers in order to create his version of Blade, the results where underwhelming compare of the perfection of Blade, they were stronger then the average irken but they will grow to be just as tall as an elite irken, he created four irkens and they where pretty different from the average irken, they have red eyes and their skin as pretty green, the smeets where pretty aggressive that when Vex tries to do the procedure they jump on him and bite him, the four irkens then where put under military training right away.

The name of this four super soldier irkens are: Pyr, who likes flamethrowers, Nilz, he uses a nail gun with a chainsaw attachment he made, War, he loves Heavy Machine Gun and finally Zeg he loves the use of Explosives.

 The training commanders were having trouble with them, they were very undisciplined and a huge headache they never deal with such savage irkens like this before, the four where taken to the best commander at he time, Commander Zir the same commander that is being training Blade and despite the hard start he manage to tame the little rascals but they still very savage and scary for the rest of the irkens.

 The four irkens where trained on what weapons they love to use and well they actually got self inflictive wounds from them because they just when for it right away and survive, then something was found about them they have some kind of healing factor that allows them to heal quickly. During the training they fight against Blade and they got easily defeated since Blade strength, speed and cool head allows him to beat the 4 little savages with ease, they squad after they got beat they saw Blade as their superior and respected him even call him "big brother".

 The four where send to a "unconquerable" planet for their first mission and they manage to conquered in matter of months because on how destructive their nature is, because of this they got the name of the "Mean Green Squad" and they went sent to places that is what impossible for normal irkens invaders to conquer or when Blade wasn't available to assists.

 The many conquered worlds got scare the hell off them for their savagery, nearly unlimited stamina and destructive power, their armies couldn't fight them for long.

 One time Zeg meet a tallest princess named Elya who was the living not fully grown image of Miyuki but with different colors, she chastise him for being a savage male irken war machine and with a superior attitude scoffs him and laughs at him, that lack of respect made Zeg hates Elya... unknown for them they will meet again in the future.

 After the incident that killed Miyuki and Fork, Red and Purple taking over as the Mighty Tallest, The squad continue to their job but Red and Purple just didn't like them, they thought they where too violent and very blood thirsty and they also they dislike Blade because he scare them. So they decided to send the squad and Blade to Planet 66, a planet that was conquered before but something happen that out of nowhere some creature dubbed as "demons" by the Gray Eyes irkens and the planet was doomed to be in possession of this creatures for a thousand years, elite irken armies where send but few returned alive or in one piece.

 In the end Nilz, Pyr and War died fighting honorably by killing as many demons they could, only Zeg and Blade survived.

 Zeg survives thanks to Blade, after he killed and entire horde with a powerful grenades but he got hurt wounded, Blade then grabs him and they went back to the abandon base and uses the last working escape pod and after patching Zeg he put him in the pod and let him go to space with a homing beacon and put the ship on stasis mode to increase his chances of survival. A ship manages to rescue the pod later, Zeg put out of stasis and greeted by Mya and custom made SIR Unit named Bobby, Zeg then violently get out of the room, Mya is fine he didn't even touch her, and tries to find out where he is, but he was stopped by Syp and Syp explains him where he was found, Zeg then re what happens to him and his squad mates which he call brothers as well as Blade on Planet 66.

 Blade manages to conquer the planet and return to Irk to report back, after his meeting with the Red and Purple he quits and disappears with no trace left behind.

 Zeg then beefed with Red and Purple decided not serve the Irken Empire, instead he s the group of irken outcasts that rescue him even teach them how to fight and how use weapons, explosives, etc...

 Zeg and the rebels manage get a distress beacon on a trash planet, they decided to investigated and found a irken small cruiser ship, when Zeg use explosives to get inside he saw who was inside by removing the metal door, the he saw a familiar face...it was Elya the irken princess that mock him and was very critical of him and his fallen brothers, Zeg just put the door back let and tells the others he didn't saw anyone inside but Mya and Xam just open the door after hearing someone screaming and bangin the door, they manage to rescue Elya, now a disgrace princess betrayed by Red and Purple because she was way more competent compare to them and a lot more smarter. Elya s the rebels and well Zeg hate it that, and to make matter worst Nya pair them up since the first mission together they manage to save the whole team from Space Pirates, sadly they never stop arguing against each other.

 Zeg keeps a mag of nail bullets, a empty flame flask and a bullet belt on his room wall to and honor his fallen brothers and he knows that Blade is alive because he says to the others:"Blade too way badass too die."

Zeg, Nilz, Pyr and War belongs to me
