Power Gem Power-Up
- See also: Metal Sonic v2.0
When Knuckles the Echidna and the Chaotix arrived at Renfield T. Rodent's carnival to save the Freedom Fighters, Dr. Robotnik sent the repaired Metal Sonic v2.0 to stop them. When Metal Sonic realized it was clearly outnumbered, it used a Power Gem to turn into the gigantic Titan Metal Sonic v2.0; however, Heavy had its own Power Gem on hand, and Knuckles used it to turn giant himself, allowing him to take on the new and improved Metal Sonic. Knuckles used his increased powers to defeat Titan Metal Sonic seemingly once and for all. (KCX)
The only ability that Titan Metal Sonic seems to possess is super strength.
- Titan Metal Sonic is based off of Metal Sonic Kai from Knuckles' Chaotix. While it was featured in the original comic continuity as a transformation of Metal Sonic, Knuckles' Chaotix never made it clear whether or not Metal Sonic transformed into it or whether Metal Sonic Kai was a separate robot.
