First How to make the Golems?

Its Quiet Simple.
You need a New Pumpkin which can be made like that:

Then make the Same Structure like by Iron Golems and then you have your Golems 🙂

All Golems there are for now:

Copper Golem (HP: 28. Attack damage: 10 - 17)

He isn't that strong To be fair so I wouldn't recommend making this one!

Next is 
Golden Golem (HP:50  Attack damage: 4 - 10)
This one is really weak but This Golem doesn't attack Piglins

(I am planning on making this one Spawn also by Piglins)

Next is the Emerald Golem (HP:230    Attack damage:30 - 50)
This Golem is really Huge and Strong
 

Other then that there isn't anything special about it

Now is the Lapis Golem (HP:60  Attack Damage:2 - 10)
 

This one is really Weak but quiet fast.

Next up is the Redstone Golem (HP: 30  Attack Damage: 3-10)
 

This one doesn't seem that strong but its the fastest
It also has a Charge attack which can one hit you+other mobs

Now the Diamond Golem (HP:200    Attack damage:20 - 35)
 

This one is just better then the Iron golem.
 

Now the dirt Golem (HP:10-13    Attack damage:1 - 10)
 

This one is weak but kinda Fast.

Now the Strongest of them the Netherite Golem (HP:250   Attack damage:30-47)

This one is really Big and does  alot of damage.

its Also Lava resistance

Next the Endstone golem (HP:56   Attack Damage:10 - 17)
 

This one can Teleport and is a little faster

Other then that its quiet simple

Next the Netherrack one (HP:28   Attack damage:10 - 17)
 

This one has makes a fire Path and has 2 versions

this is randomized.

Obsidian Golem is the Biggest of them (HP:200   Attack Damage:30 - 47)

 

This one is also is Fire resistance so I more would make this Golem then the Netherite one

Next is the Most Dangerous one the Tnt GOLEM (HP: 20    Attack damage: Explode)

 

This one when near a threat will Explode itself to kill a lot of things

Now thats all!
All Golems need the same Structure and also drop their thing their made out of
