"Endangered Species," Part Three. The battle between Knuckles and Thrash the Devil rages on! The battle against Dr. Eggman's forces was sidetracked when Thrash erased the entire echidna population-- and Knuckles isn't taking it lying down! Can Team Fighters even the odds when the Krudzu Hybrid Hyrda shows up?
Endangered Species Part Three: Restoration Efforts
Meanwhile, Team Fighters are having trouble taking on the Hybrid Hydra, while a pair of eyes scopes out the situation. Sonic acts cocky as usual, saying there's no Badniks to morph with, when the Hydra begins to bond with all of the broken technology left from the earlier battles with the Dark Egg Legion. Just then, a familiar black-and-yellow Spin Dash hits the Hydra, and Shard reveals himself, surprising Amy, Tails, and most of all Sonic.
This issue marks the first time Shard has shown himself to Sonic in his new form.
The final cover for this issue was given some slight changes in comparison to the original preview of the cover; the metal wires grabbing Sonic had plant vines entangling them (as a reference to the Krudzu Hybrid Hydra). Also, the countdown to the Sonic & Mega Man: Worlds Collide event and the mark for the 20th anniversary of the Sonic the Hedgehog comic book series were added as well.
The Worlds Collide countdown on the cover incorrectly says 4 instead of 3. This same error is also present on the cover of Archie Sonic Universe Issue 48.
The metal vines entangling Sonic were actually from Lien-Da. It is unknown how or why this would have occurred, due to the Ken Penders case that cause all of his characters to be removed from the storyline.
