Review: Perfect add-on for a Lego set - My 8 yr old grandson wanted this for another super creatures Lego set he has. He saved his money and gave it to me to purchase this for him. It arrived several days early and he was beside himself with joy. Today he showed me the whole set that he has put together. It looks great, complimented his Marvel folks, wasn't missing any pieces and he was quite happy with how he was able to make it work the way he wanted it to. I think it is a good toy for the price.

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 ### ⭐⭐⭐⭐⭐ Perfect add-on for a Lego set *by S***E on March 30, 2021* My 8 yr old grandson wanted this for another super creatures Lego set he has.
