## Plot

The episode begins with Gamma, Daisy, and the Elite Phi Troopers land in Kenya, Africa and have to locate E-121 Chi. The yellow Fly model reports that a lot of Phi Troopers and Guard Robos were sent before E-120 Phi was destroyed.

Meanwhile, Chi sends out his bodyguard robot army to stop Gamma and his troopers, but, the elite troopers sent out energy balls to destroy the rest of the Phi Troopers and Gamma uses Guard Mode to protect himself from the Guard Robos long enough for the Elite troopers to use Triple Impact on them. Chi himself then appears to face off against Gamma with his Chi Flashknuckle using his power, Chi Power Charge. Unfortunately for Chi, Gamma uses his Chaos Gamma mode to use Solid Knuckle and the two power balls collide. Gamma uses this to signal to the Elite Phi Troopers to clear out.

Gamma, now damaged, tells his fellow troopers to help form a new strategy. The reformed E-100 robot remembers something he saw in Japan and researches it on the internet. Turns out the thing he remembered was a Kamen Rider Kaixa, another copy-cat idea from Eggman. They realize a lot of users utilize the system and they decide to learn how Chi's weapons work. After a hiccup with Yellow Fly's anti-virus system, they finally reach Kaixa.

Before Gamma can begin to attack, Chi does so first. The Elite Phi Troopers get into defense around Gamma, but, are a bit slow because Gamma's Recovery Mode is interrupted by Chi's second punch. Gamma isn't ready to give up and gets into a fistfight with Chi. After taking a shot at Chi's ego and while Chi is taking a stab at Gamma's hopefulness, Gamma uses an electric stab which signals the Elite Troopers to strike while Gamma uses Recovery Mode. Daisy warns Gamma to duck from a laser sword and Gamma uses his Paralyze Dagger on Chi. This frees the Mobini Lion, who races away and roars gratefully. Gamma realizes there's two units left to destroy: Psi and himself. Much to the friends' shock though, Chi has a bit of strength left from a backup power source, which is glitchy, and he warns the group that Gamma's eldest brother is the strongest and will swiftly and painfully kill him. Despite the fact the message is flawed - Psi is the youngest and swift deaths aren't as painful as slow ones - the robots know this last battle will be a tough one as they fly away.

At the Mobini Ranch, the Mobini Lion jumps through the portal to greet Amy, Manic, Chris, and Hope. Chris is surprised to see a Mobini lion and Amy allows him to pet the newcomer. Lions can also improve Chao's power stats. The group realize Gamma has one battle left against Psi, but, Hope realizes Psi is a very powerful E-100-Series, about as powerful as E-99 Eggsterminator without the Chaos Emeralds. Manic remembers how he, Sonic, Sonia, and Sally had to turn Super in order to take it down and how Abraham Tower gave them Invisibility Shields which saved their lives, but, poor Amy is stressing over the memory and the fact Gamma has to fight Psi. The group hope for Gamma to win his last battle as the episode ends.

## Trivia

* Brandon, Blake, and Riff break the fourth wall at the start discussing the time placement of the episode and Brandon interrupts the story by using Africa by Toto as montage music.
* Though lions are in Africa and North America, there is another type of lion in India called Asiatic Lions. Some of these appear in the Lion King's spinoff series, The Lion Guard, in the latter part of series 3.
* The Mobini Lion was unintentionally foreshadowed in the Special 5 when Chris mentions The Lion King and its leading two protagonists, Simba and Nala.
