This is not a reskin of the Iron Golem; it attacks in a completely different manner (by throwing blocks at enemies).
This golem would be created by placing 9 obsidian, 2 redstone dust, and 1 dispenser in a shape seen in this image. It has 100 hp (same as an Iron Golem), but has a 33% damage reduction from arrows and explosions, and is completely immune to fire, drowning, negative status effects, and falling. It looks slightly like an iron golem and has similar arms, but is bulkier and has a different face (not based off of villagers) with red eyes.
After creation, it would stand in place and be completely immobile, until you open its inventory and load things into it. The inventory would either be 9 slots (like a dispenser) or 5 slots (like hoppers). Only solid building blocks softer than Obsidian can be loaded; tall grass, stairs, or anything that is a block entity (chests, note blocks etc) won't work.
When activated and noticing a mob, it will take the block in the first available inventory spot, hoist it onto its hands and throw it at the mob. The reloading time for this is around 1 block every 2 seconds. The range and damage depends on the block's hardness. For example, dirt would do 5 damage (2.5 hearts) and have a horizontal range of 20 blocks, while cobblestone does 12 damage but only has a range of 10 blocks (and moves slower). The thrown block deflects arrows and would keep traveling until it hits a solid block and breaks (with a small chance to drop as an item).
The golem will attack all hostile mobs except for Endermen, Ghasts and Creepers (unless the creeper is sufficiently far away). It moves quite slowly and attempts to back away if its target gets too close, but won't attempt to give chase and will lose interest if its target gets out of reach. It can spot mobs from 24 blocks away (including downwards), so you can potentially station golems on top of a castle wall and have it throw blocks at mobs to defend your castle.
When its inventory runs out of usable items, the golem will make a clicking sound and become completely inactive. In this state it will not even respond to mobs attacking it. If killed by anything, it drops 4 obsidian and 2 redstone dust.
Basically, this golem is mostly intended as a form of short ranged defense, and wouldn't fare well in a melee encounter due to its slow attack and movement speed.
The dispenser and the Redstone Dust should be respectively replaced with a Pumpkin (All other golems use them, so this would be keeping consistency) and 2 Tripwires (As if they were used to make the arms capable of launching blocks).
Replacing the dispenser with a pumpkin could definitely work, although I still prefer if there was a dispenser in there somewhere since the golem shoots projectiles and has an inventory (it could go under the pumpkin block).
The main reason I wanted Redstone in there was to symbolize the mechanical nature of this golem; it only does things if there are blocks loaded in its inventory, and deactivates otherwise. Tripwire isn't a very strong binding material anyways.

This seems balanced, original, and useful. I could definitely see myself using these guys if they were added to the game.

Support. This is a well-balanced and well-detailed suggestion.
Check out my suggestions! Here is one of them:
