Meanwhile, Superdog stops a stolen LuthorCorp vehichle. After stopping the robbers, Krypto speeds through the lab and grabs Kevin, arriving at graduation just in time to get his diploma.

After graduation, The Whitneys and Susemans have a graduation party for Kevin and Andrea, but Krypto becomes distracted by a high-pitched sound and speeds, leaving Kevin worried at his disappearance. While flying to LexCorp, Superdog is attacked by Intergang, using LuthorCorp's experimental battle suits and fights them off, getting weaker and weaker, realizing that they're using Kryptonite. After defeating the first two, Superdog is defeated by the third and crashes into LexCorp unconscious. Waking up, Superdog is surrounded by Kryptonite with Ignatius standing above him, holding a red crystal that he reveals to be Red Kryptonite. He opens up Krypto's "S" Shield and places the red kryptonite within it, in which Krypto's eyes flash red for a moment.

At the Daily Planet, Kevin and Lois talk about the Intergang attack from last night, as Krypto repeatedly barks. Andrea runs in and tells them about an attack downtown. Rushing out to cover the story, Kevin notices Krypto laying down, ignoring Kevin, who yells at Krypto to go stop the attack, so Krypto carelessly speeds out, purposely knocking down Kevin. Superdog arrives at the scene, destructively stopping the same attackers from the night before in LexCorp battle suits. Tearing apart the suit, Superdog nearly kills the criminal, until Lois yells to him not too.

Kevin confronts Krypto on what he did, and Krypto hits Kevin, causing him to fly into the wall. Krypto grabs him, until Andrea arrives with a piece of Kryptonite, so Krypto faintly flies off. They return to the Daily Planet to tell Lois what happened, so she tells them to locate Krypto while she calls a friend.

Meanwhile Superdog is attacking LexCorp, destroying all the battle suits Lex Luthor is supplying Intergang and prepares to kill Lex, until Kevin arrives and demands that he comes with him, but Krypto continues to rebel, so Kevin opens a container holding kryptonite. Before getting too weak, he uses his heat vision to destroy Kryptonite and prepares to blast Kevin, until a masked canine dives in and pulls Kevin out of the way, revealing himself to be Ace the Bathound. Bathound attacks Superdog, but Superdog knocks him through the window. Bathound uses a grappling hook to swing back up and shoots two Kryptonite lined batarangs at Superdog, who blasts the first one, but is hit by the second, causing him to fall ill.

They take Krypto to be analyzed by Emil, but Dr. Hamilton discovers that he's been doused by Red Kryptonite, unable to find the source. Krypto is strainly injured by pulling out the batarang with his teeth, but recovers and attacks the group and leaves. Bathound walks outside where a rocket kart similar to the Batmobile is arriving, he hops in and drives off, using a tracker to follow Krypto

Elsewhere, Andrea is taking a walk with Streaky, but is confronted by Superdog, who knocks her, along with Streaky into the Daily Planet and chases them to the basement. Andrea attempts to hide from him, but he finds her with his X-Ray and almost attacks her, until Bathound arrives and saves her. He attacks Superdog, but Superdog hits him into the wall. Streaky gripes at the Dog of Steel and attempts to claw him, but Superdog throws him into the generator. Bathound tries to save Streaky, by shooting batarangs at Superdog, but Krypto destroys all but one of them, which hits the generation, causing green, kryptonite lined electricity to electrocute them. Kevin arrives and gets Andrea and Streaky out, as Superdog again attacks the Bathound. After a short battle, Bathound barely escapes.

He returns to S.T.A.R. Labs, where Dr. Hamilton is bandaging Andrea's wounded leg, with Streaky laying, severely damaged by the electricution. Kevin points out that there's no way to beat Krypto, since he blast every piece of Kryptonite they try to use against him, but Dr. Hamilton tells Bathound that he took the liberty of calling the dog's "partener", when suddenly the Bat-Wing flies by and drops a large metal package, crashing into the lab. It opens up to reveal Batman's "Red Son Battle Suit", the battle suit Batman once used to take on Superman, wih a power source imitating Krypton's red son, Kryptonite lined weapons, and enhanced strength and agility, so Emil begins tampering with it to fit Bathound.

While rampaging through the city, Superdog sees the Bat-Signal in the sky, coming from the Daily Planet and flies towards it. As it begins storming, Superdog hovers in the sky above Bathound, wearing the Red Son Battle Suit. Superdog zooms towards Bathound, but Bathound dodges him and Superdog crashes into the ground. Bathound shoots a grappling hook to grab Superdog and zip kicks him. Superdog throws Bathound against the wall, and Bathound gets up and tackles Superdog off the building. Bathound grapples onto another building, as Superdog begins flying before hitting the ground and attempts to blast Bathound with heat vision, but Bathound jumps off and grapples into Superdog, causing them to crash into the Daily Planet, as Ignatius and Lex Luthor watch from LexCorp. Back at S.T.A.R. Labs, the others moniter the battle, when Kevin suddenly remembers that Krypto's House of El dog tag can be opened to use as a container and tells Bathound to destroy it. After a long battle, Bathound appears to be losing as Superdog tears off the armor, before realizing a beeping batarang stuck in the "S" shield, destroying it, along with the Red Kryptonite. Superdog shortly comes to his senses and they return to S.T.AR Labs, where Emil asks Krypto the last thing he remembers before being infected.

Superdog and Bathound arrive at LexCorp to confront Ignatius, who is wearing the final model of the LexCorp's battle suits and begins the final battle. After a short fight, Ignatius begins blasting Superdog with a Kryptonite ray, but Bathound uses explosive batarangs to destroy the arm of te exo-suit.
