With many destroyed Ultron Sentries from the Battle of Sokovia, HYDRA collected many of the parts and took them to an undisclosed location in Eastern Europe, where they used the parts to create a giant robot called Ultimo. HYDRA then used the Ultimo to attack a small village. The Avengers reacted to the attack and destroyed Ultimo.

- In the non-canon video game Iron Man 2, Ultimo was a large battle suit worn (and fused with physically and mentally) by Kearson DeWitt. Ultimo was voiced by Andrew Chaikin.
- In the comics, Ultimo is an alien robotic construct created thousands of years ago, that caused the extinction of the Rajaks and it was used as a weapon against Iron Man by the Mandarin.
