Meanwhile, the Battle of Mikatagahara is about to begin.
The Alpha Gang run into the D-Team and an attack by Terry results in Zoe, Tokugawa, and a bear cub being trapped under a pile of rocks. Max and Rex transform Chomp and Ace to help get them out. The Alpha Gang are also forced to help out.
During this, Ace gets attracted by the White Cosmos Stone. When Zoe, Tokugawa, and the bear cub get out, the bear family starts chasing the Alpha Gang again, and Rex appears with the Cosmos Stone.
Gavro then attacks and unleashes his Baryonyx. Rex summons Ace, but Chomp and Paris are needed also. During the battle, Tokugawa gets away with the White Cosmos Stone with some assistance from Hanzou while Chomp defeats the Baryonyx.
Gavro goes after Tokugawa while the D-Team has a run-in with a larger bear.
D-Team vs. Gavro/BaryonyxEdit
Gavro summons a Baryonyx and attacks the D-Team. Ace is summoned to fight Baryonyx, knocking him back.
Baryonyx uses Aqua Whip, nearly defeating Ace. Max and Zoe summon Chomp and Paris, who knock back Baryonyx, freeing Ace. Seeing he's beginning to lose, Gavro activates Baryonyx's Spectral Armor, but the D-Team equipping their dinosaurs with DinoTector Armor.
Gavro then goes straight for the Cosmos Stone, but as the D-Team try to defend it, Hanzou swoops in and grabs it, then escapes with Tokugawa.
Seeing a chance to attack, Chomp defeats Baryonyx with Thunder Driver.
(as Gavro reaches for Rex and the Cosmos Stone, Ace jumps up and bites his hand, but is thrown off)
-Gavro: "Hey, pick on someone your own species!"
- When Baryonyx slams Ace into the ground with Aqua Whip, the hits are in time with loud beats in the battle's background music.
- The title of the episode is based on the phrase "Lions, Tigers, and Bears! Oh My! from the 1939 MGM classic film, The Wizard of Oz.
