Power Dagwon is formed from the Herculean Combination of Dag-Fire and the Fire Shovel. He can then combine with the Fire Jumbo, Fire Ladder and Fire Rescue to form Super Fire Dagwon.
Power Dagwon is created as an emergency replacement for the unusable Fire Dagwon configuration due to the Fire Jumbo being heavily damaged. Compared to Fire Dagwon, Power Dagwon excels in strength, easily wrestling the gigantic Queen Zargoss with ease. He can travel quickly in Robot mode using his leg treads or transform into a Power Tank Mode by kneeling on his legs for maximum speed. Power Dagwon now also has a dedicated connector for the Infinity Cannon/Gunkid to combine with, boosting its power.
In Episode 30, the Fire Jumbo was temporary lost in the ocean when En rammed it into Ark Seijin's castle to stop his plan of freezing the Earth, rendering Fire Dagwon useless. When the Dagwons are overwhelmed against Queen Zargos and her invading Zargos Seijin armada in Episode 31, Luna, who was at Earth at the time, decided to transform a nearby excavator into the Power Shovel for Dag-Fire to combine with, stating that although this is a violation of the rules but an one-time exception shall be made. After combining, Power Dagwon made quick work of Queen Zargos along with the Zargos Seijins' mothership.
Despite regaining the use of Fire Dagwon in episode 38, En would still continue to primarily use Power Dagwon, particularly for it's much greater durability and attack power.
Power Dagwon's last usage would be in the final showdown against Genocide after the entity possessed Fire Dagwon. En would later force a combination into Super Fire Dagwon and engage with the entity in a battle of willpower as they rocketed towards the Earth's stratosphere. En eventually won, but the strain of both Super Fire Dagwon's inherent instability and the strain of breaching Earth's atmosphere wound up being too much for the mecha, with both Fire and Power Dagwon disintegrating to nothing by the end.
