The Defense Mechanism of Alto Mare, also referred to as the DMA, is an ancient machine situated in the Museum of Alto Mare. This machine was constructed numerous centuries ago, with the goal of protecting Alto Mare from danger. The Defense Mechanism requires both the Soul Dew and either one of the Eon Pokémons to operate it. In Pokémon Heroes, Oakley takes control over the Defense Mechanism in order to subjugate the city. The Defense Mechanism was eventually destroyed when Latias used Safeguard to render the machine inoperable.
The Defense Mechanism is shown to have a sophisticated control system over the entire city of Alto Mare, as Oakley was able to place it in lockdown. It is also able to control the waters of Alto Mare, contorting it into various shapes with the user's hand movements. The Defense Mechanism also has the ability to revive fossilized Pokémon, namely the Aerodactyl and Kabutops skeletons in the Museum of Alto Mare. However, overusing the Soul Dew (in the manner which Oakley utilised) can cause the power source, the Soul Dew, to fracture under pressure.
- Possibly, ancestors of Bianca and Lorenzo (or residents of Alto Mare) established the structures and functions of the DMA after the incident mentioned in the "folklore", however it has not been described how the usages of the "Soul Dew" with functions beyond human understanding were achieved, including the system of DMA (possibly with helps from Latios and Latias).
- The reasons is unclear about why Latios and Latias in the past agreed with to help activating the DMA despite it is very dangerous for them to work as energy sources.
- Other than self admonishment, the reason why there has been a drawback left in the DMA to call a fatal crisis to the city of Alto Mare is unstated.
- There is another possibility that "the unknown being that has the shape of a human arm and is attached with the DMA" which was seen in the earlier trailer, was a draft of the identity of the "monster" told in the old story.
