his Zetanian kid known as #97 is Saku. Sure, he may be a pretty young kid, but he is actually a bunch of hell to deal with! See that jackhammer pogo stick he has? That is his main weapon and it can actually do many things! Some Zetanians are even scared of Saku because of how dangerous he is in battles, even knowing the fact that he terminated (Or killed) about 4 or 5 Zetanians too! The things he can do with his weapon are these :
Pogo stab - Jump high in the air with his weapon to stab his opponents from above.
Drill - Cause a bunch of rocks to be drilled out of the ground hard enough to make the rocks fly in a ballistic way.
Pogo ricochet - Yes, he CAN actually use his pogo jackhammer like a hook shot to make the blade bounce in different directions to hurt his enemies! He does so by lifting his weapon and pointing it at his opponents.
Hook shot - Sometimes he uses this as an advantage to dodge from enemies or to quickly get to different platforms.
Burrowing and emerging - This is one of his strongest and deadliest attacks! He drills underground making his opponents unsure where his is until He quickly emerges under them while attacking under them with his weapon!

Nobody knows if Saku has a Zetanian master or mistress yet, but Plenty of Zetanians that know this kid hope that he might have one because of how unbelievably dangerous and mischievous he is since he's a kid.
