Probably wont happen in official Smash game I thought it would be fun to explore how this thing would fight and surprisingly there is enough stuff to make a whole move set especially if we use references from CTR and he is even a mini boss in Crash On the Run lets see how it can be a fun character to add after Crash Bandicoot due to having simple animations also many people loved the inclusion of him in CTR.
Alright lets start:
Intro: Falling down from sky like in Crash on The Run mini boss.
Taunt 1: Iron Checkpoint Crate will open and Uka Uka will come out and laugh.
Taunt 2: Iron Checkpoint Crate will be fully opened.
Taunt 3: Iron Chekpoint Crate will drift with his car.

Victory 2: Iron Checkpoint Crate will drive his car from far away and drift close to the screen.
Getting Hit:
Down:
Side Smash: Uka Uka will hit side way.
Down Smash: Uka Uka will spin around you and hit down both sides.
Up Smash: Iron Checkpoint Crate will open and launch TNT or Nitro upward and it will explode.
There is 75% chance it will be TNT and the count on the TNT will be on 1.
There is 25% chance it will be Nitro and it will deal more damage than TNT.

Side Special: it spawns a car and it works Like Bowser Jr. side special
Up Special: Spawns Arrow Crate to jump from it works similar to Sonic up special but the Arrow Crate can stay in the air and it can be damaged.
Down Special: Obtain Beaker item which can be thrown and it deals damage while having poison effect keep in mind you can damage yourself if you hit yourself with it.
There is 75% chance it will be the regular Beaker.

So what do you think? I am pretty sure this move set can get updated due to Activision using him more as an actual a character in the newer Crash Bandicoot games and probably more to come in the future for Iron Checkpoint Crate.
