The normal route follows the Any% Ostrich 3rd path, there's a harder route that I'm not sure of exactly but it does Centipede 3rd and has some difficult tricks.

I came up with this strat for Serges:

Not sure if there's a better way but this turned out well. Only things to note are holding left into the wall to dboost quickly, then letting go of it when you fire the slicer seems to double hit him consistently.

You do take a lot of damage, but this seems good to me. Also getting hit by his cape at the start instantly fills your Giga Crush energy, if you ever need that.

I just follow the any% route with Ostrich 3rd. I wasnt too sure if there was a better aproach to the X-hunters. I didn't want to go too far out of my way to reach them. Im going to have to try Trogdors strat sometime. Looks awesome

If he doesn't jump at the start, you can just try a double hit by putting the slicer barely in front of him. If he does jump though, this should work every time.

Awesome. I think ill try to get my any% down to where i want it then ill come back to this. I mainly did 100% just to see my time difference. Which was lower than i expected.
