|The Return of Corey|
|Revenge Saga, Episode 30|
|Air date||March 4, 2012|
100-Fold Gravity Challenge
Ed and Eddy continue fighting the mechanical Sonic doppleganger, but the fight quickly turns against them once Mecha Sonic really decides to get serious. In the process, he knocks Ed out, reverting him to normal. This results in Eddy getting mad, and he gains a rage boost, enough to temporarily put him on the robot's level of power. However, after Eddy uses the Final Flash, Eddy cools off, and is swiftly defeated.
Just as all hope is lost, Corey arrives on the scene with Tailsko. After deflecting the weak kill shot, he reveals his full power of 110,000 and proceeds to take up the battle with Mecha Sonic, his power level 2,200,000 with the Kaioken x20. Meanwhile, Tailsko heals up the heroes. Meanwhile, Jonny is showing clear signs of stress due to the overuse of Nature Mode (the fact he's not trained to handle large amounts of power for extended time periods doesn't help matters).
Though Corey's power is higher and he's able to turn Mecha Sonic's Kienzan attack back at him, he is unable to finish him before he once again escapes with Chaos Control. The cascade of revelations post-battle lead to the heroes being moderately shocked at the fact Tailsko is Tails' long-lost older sister, and moderately disgusted by the possible relationship between Corey and Tailsko, but Shadow is able to restore the heroes' focus on the matter, and thus the heroes resolve to train at 100 times Earth's gravity.
