The Dark Dummy Sparks (ダークダミースパーク Dāku Damī Supāku) are transformation devices carried by Alien Valky which is an opposite of the Ginga Spark. The Dark Dummy Sparks seem to be inferior copies of the Dark Spark which turned all the Ultras, Aliens and Monsters in to Spark Dolls. Its light counterpart is the Ginga Light Spark.
After the Dark Spark War rendered Lugiel powerless, he quickly possess the nearby host Kyoko Shirai and sent on his Dark Agents to endow his targets with the Dark Dummy Sparks. Each time the victim uses them, their Minus Energy were siphoned to Lugiel and allows him to revive himself.
By the time Alien Nackle Gray defeated, Lugiel managed to gather enough Minus Energy to revive himself and at almost succeeded in turning the entire life on Earth into Spark Dolls until his efforts were thwarted by Ultraman Taro and Ginga.
Ultraman Ginga S
- Telepathy: Users of the Dark Dummy Spark can communicate with others telepatically as shown when Seiichiro used the deivce to communicate with Hikaru.
- DarkLive: As inferior replicas of the Dark Spark, the Dummy Sparks can allow the corrupt minded to UltraLive with a Spark Doll and transform into it.
- Combining Spark Doll: The Dark Dummy Spark can combine any Spark Dolls to Live them into one combination monster as seen in use by Alien Icarus.
- Mind Control: Those wielding a dummy spark are made slave to their inner darkness. They begin to act out on their darkest desires and/or inner insecurities, committing acts they normally would never consider. in some cases the user is literally being controlled by outside forces, mainly Dark Lugiel.
- Spark Doll Corruption: Like the Dark Spark, a Dark Dummy Spark can corrupt Spark Dolls as well if the figure itself is a warrior of justice. In Ultras' cases, they would turn into their dark counterparts.
- Minus Energy Manipulation: The true potential of the Dark Dummy Spark is to siphon the Minus Energy (マイナスエネルギー Mainasu Enerugī) from humanity's darker heart to Dark Lugiel as part of reviving himself.
- Being an inferior imitation to the Dark Spark, an anomaly in this device could occur when an individual who has a neutral intent uses it, causing the individual to maintain his sanity. This weakness was revealed in episode 6 of the Ultraman Ginga series by Tomoya Ichijouji.
