## Questions & Answers

**Q: Is it easy to change it from a mech to a jet and back again?**
A: Hi there! When we label a set as 2-in-1 or 3-in-1, that means you will need to take apart your build entirely and rebuild it. - Emily, LEGO® Customer Service

**Q: Sorry, i need to clarify my last question. this may be kai’s mech jet, but is it kai in the mech. some think it’s zane or jay!**
A: Kai is who is in the mech jet! The set does come with another action figure and that is Richie!

**Q: How tall is it**
A: The body of the mech when assembled is about 7 inches tall and the swords make it look even larger! My 11 year old plays with it all the time, he has not dismantled it since he built it a year ago!

**Q: Is this Kai’s Mech or Zane’s?**
A: As the toy's name states, this is Kai's Mech.
