Zach (The 15 Keys)

Zach only appears during Forsaken Chronicle vs 15 Keys, and has his own story scenario

Forsaken Chronicle VS 15 Keys
Directly after the events of Nightfall Zach finds himself in an unknown world, his powers reaching their full potential. His super form fades and the seven gems are dispersed across the new world, begginning Zachs quest to find them and take them home.

First Act
Gage and Zach have both discovered the location of one of the gems, however Zach instantly feels that his intentions are dark and quickly attacks Gage. Gage questions Zach as to why he wishes to hinder his progress, to which Zach simply fires a few Chronos Spear attacks and the battle begins. During this battle Zach lacks all of his abilities and can only use his Boost to dash, Chronos spear for ranged attacks and his special ability is to use his trump card Super Flash, healing him and restoring his Chronos Energy. Zach easily defeats Gage and uses the super flash to get closer to the gem. He takes it and leaves with it.

The Bluebird
Zach is confronted by the Bluebird while searching for his next gem, when suddenly Maddy and Hopey appear in the world, confused. The Bluebird mistakes Zach for Kona and upon discovering he is not Kona attacks him, triggering a high speed battle with The Bluebird using the Blue gems power to fly. As Zach has recieved his superform back he can now switch to it after three super flashes. FInishing this fight in normal form causes Bluebird to leave with the gem, however defeating her with above 25% energy remaining while super earns the blue gem early.

Teaming up with friends
Zach obtains his next ability, team attack, and is then attacked by Bluebird again, though this time she has returned with Kona. Zach and Hopey are momentarily caught of guard by the attack, but Konas power proves no match for Zachs speed and Hopeys strength.
