Many of the sets of the HERO Factory line could be rebuilt into Combiners (or Combination Models). No Alternate Models were released, however. These models reused the pieces from HERO Factory sets to construct an additional figure. Instructions for combiners were released in various formats, such as being posted online or being featured in magazines published by LEGO.
One combination model was released in 2010 through the LEGO Club Brickmaster Magazine. It combined three of the first wave heroes to make Lucas Valor.

Like in the prior year, a combination model was released through the LEGO Club Brickmaster Magazine. This one combined all six 2.0 heroes to create the villainous character Makuro-X1.
Another six combiner models were released online - three for the winter wave, three for the summer wave. These combined the heroes in pairs to create larger Hero-like models, however these never appeared in the story. Some, if not all, of these models were also made available in two-pack sets in Korea.

Two combiner models were released through LEGO Club in 2012, however unlike past years, these were also made available online. The first combined the pieces from three of the winter wave hero sets to create a rookie member of the Alpha 1 Team. The other combined the three respective villains to create an unnamed villain.
Each of the nine hero and villain pairs released in the year featured a combiner model for which instructions could be found online, depicting other villains. Some, if not all, of these models were also made available in two-pack "Mission Packs" in Korea.

Like the previous year, each of the hero and creature pairs released in 2013 featured a combiner model for which instructions could be found online. In this case, they were said to depict "Ultimate" versions of the heroes, using parts of the creatures to upgrade the heroes, however these never appeared in the story. Some, if not all, of these models were also made available in two-pack sets in Korea.

In 2014, a combiner model was released online depicting a "Powered-Up" version of the Evo XL Machine, using parts from the other four winter-wave hero machines.
Other instructions for combiner models were also released online, depicting beasts and machines different from those seen in the main models of the sets. Each combiner used two or three sets.
