Finally, you face the Big Bad Himself. There are 9 Doom Striders in the first section, you use a jump pad to get to ziplines in which 2 drop you down into a pool of fusion matter. You use bobbing rocks to get out to where Jack is, with 6 more doom striders, which were once Striding Eels. Then you use ziplines to get to Fuse
Note: At the left corner where Fuse is, there is another Fuse (now called Clone Fuse) who does not use Eruption but only uses his hands. Because of this, the player could be K.O'ed fast.
