After the first year, development of the series went to Foundation Imaging, an animation company which eventually declared a bankruptcy at the end of second series. Mattel then choose Rainmaker Entertainment as the main animation studio, which at the time also was in charge of . Following the same formula as Beast Wars, once Mainframe took control of the production, every new toy makes an appearance in the series or the movies, so they finally made a match. After the "Endangered Species" movie, every new set of toys includes at least a couple of wild animals as companions of Max too. The original run of the original toy series began in 1999 and ended in late 2013, with the reboot of the TV series. Since the toy line was intended solely for male kids, despite of the constant presence of empowered women in the series as main or supporting characters, no female figures were ever produced.

As part of this decision, Playground Productions, Nerd Corps Entertainment and FremantleMedia Kids & Entertainment created a completely different origin story, and Mattel produced new toys based on the new designs, notoriously different from the original ones. The most notable change was the drop of toy's clothes and wearable accessories. While the original action figures came with fabric made vest and pants and detachable or snap-on accessories, -thus allowing to undress or dress up the figures with additional gear-, the new ones had no clothes at all, and all their features were directly molded onto the figures surface. This also allowed Mattel to cut down the cost of production of the action figures. The new figures also lacked of spring, sound or light features, which were not included until 2015, but in limited figures only. The new reboot series was also notorious for the release of Max's allies for the first time. In the original toy line, only Cytro was produced as Max's crime fighter companion. In the reboot series, additional to Cytro, Forge Ferrus and Ven-Ghan (Vengeance) action figures were released. Also another notorious change it was the New Max Steel figures from 2013–2016 were molded and shaped as a 16 year old kid, notoriously younger and less muscular than the original ones, but figures made after 2016 were retooled to emulate a 19 year old boy, making this the very first time Max showed some aged in both, toys and series.
