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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Ótimo produto, meu filho adorou! *by S***Y on 15 July 2021* Ótimo encaixe de peças, bom de montar.
