You decide to fix it. Zero says: Dr.Cain must have upgraded my Z-Saber while I was sleeping, I left it out last night. X agrees to let you fix it. X says: first, we'll need some parts. X Again: Down at Auto's fix-it Shop, we should find some. Zero says: Yeah, but there's one tiny problem. X looks up and they say simulataneously: MAVERICKS ! You and X run down to the garage and looks around the huge mechanical storage facility. You see 2 hoverbikes and you see 2 hoverboot pairs. Hmmm.... Zero says: They both are A's on my list!

The Hoverbikes are more efficient.
The Hoverboots are definitely faster
