While investigating anomalies within the game world of SDBH, Great Saiyaman 3 heard about someone who had managed to enter the game world and was able to retrace their steps using the data from said journey to design both the Hero Switch and Hero Lab.
The Hero Switch can also allows the user to take the race and type of their Hero Avatar (if the Hero Switch user uses a Hero Avatar that is a different gender from the user's real world gender then their gender will be altered to that of their Avatar). Once in the game world, the user can utilize their Hero Avatar's abilities to physically fight other users or characters in-game. Additionally, the process also works in reverse allowing the user to utilize the power of their Hero Avatar in the real world. Additionally this may also lead to the user to manifest special powers such as gaining the ability to transform into their own version of the Great Saiyaman Suit with the Hero Switch serving the same purpose as a Great Saiyaman Watch though the only occurrence of this was when Beat's Hero Switch manifested a red and yellow version of the Great Saiyaman 3 Suit, due to Beat idolizing the Hero Master, with Beat proudly dubbing himself Great Saiyaman 4 upon acquiring the suit however this only applies to the Super Dragon Ball Heroes: World Mission Crossover Story Event in Dokkan Battle.
In World Mission, Great Saiyaman 3 has Leggings and Anne install the Hero Switches with a new feature that allows the user to fight in the real world of Dragon Ball by tapping into their latent power, giving them all the fighting abilities used in the game world in normal reality. This feature is activated using a new switch added to the Hero Switches by Leggings and Anne. Flipping this switch activates the new feature causing the user to take on the form of their Hero Avatar.
In the background of the Hero Lab behind the holographic globe is a computer screen that displays schematics data on the Hero Switch. Additionally promotional artwork such as the box cover for Xeno Mission depicts Beat activating his Hwro Switch which forms around his hand in a manner similar to the Hero Lab's Hero Switch schematics depicted in-game. According to Great Saiyaman 3, the Hero Lab was created using data from his trip into the game world which also led to the development of the Hero Switch.
- Built-in Suit Materialization Function
Beat however asks if he can use the Hero Switch to wear the Hero Master costume and Great Saiyaman 3 allows it, with Leggings revealing that the Switch has a built-in function that can instantly materialize the uniform and that Leggings was hoping the whole DBH Team all use it from the get-go, but the Hero Master and Anne stopped her, she explains how to activate this function to Beat causing his suit to materialize and Leggings suggests he go by Great Saiyaman 4, which he accepts. It is also revealed that like the original Great Saiyaman Suits, only certain people like Beat and Leggings thinks her design of the Hero Master's suit and Beat's suit is cool as Anne, Note, and even Great Saiyaman 3 are not as fond of it and Note has no desire to use said feature. Froze and Kagyu also do not utilize this built-in feature either.
Apparently Great Saiyaman 3's suit is also materialized by his Hero Switch given it is a built-in feature and he could utilize his deck in the real world even before said feature became available to the others through he could already fight in the real world by himself without the Hero Switch or his suit. As Leggings states all Hero Switches are designed to utilize the built-in feature indicating they all were intended to serve the same purpose as the Great Saiyaman Watch, but Anne and Great Saiyaman 3 prevented her from revealing it before Beat asked if he could wear a suit like the Hero Master's and Great Saiyaman 3 gave Leggings permission to tell him about it.
Beat and Xeno Trunks are the only members to utilize this feature though according to Leggings it is available to all Hero Switch users as a built-in alternative to their Hero Avatar (as she originally intended for the team to use the suits to allow them to fight in both the real and game world however Xeno Trunks & Anne disapproved). Additionally after installing the feature to allow them to take on the form of their Hero Avatar, the built-in feature was rendered largely redundant as Best was the only one who elected to use it. After Xeno Goku and Xeno Vegeta are sent in by Chronoa to assist the team, they convince Xeno Trunks to drop his Great Saiyaman 3 identity as they see it as unnecessary. However Beat continues to utilize his suit while training under Xeno Goku & Xeno Vegeta with Note and Kabra. Since the suit allows Beat to use his body's natural potential without his Hero Avatar, his power skyrockets (likely due to Saiyan Power) causing Xeno Vegeta to realize Beat has Saiyan heritage and that he is a descendant of the Son family. This is later confirmed when Great Saiyaman 4 transforms into Super Saiyan Beat (without the use of a Saiyan avatar) after becoming enraged at Legendary Super Saiyan Broly for seemingly killing Note with a Ki Blast (in reality it just knocked her out cold). Additionally suit automatically deactivated when Beat transformed indicating it is incompatible with his Super Saiyan form (which makes Beat stronger than Legendary Super Saiyan 3 Broly).
- Hero Switch Menu Screen
Additionally the Hero Switch allows the user to access different SDBH game modes or move around Hero Town more easily by activating its holographic menu screen. However Hero Switches are not available to the general public and are only given to members of the Dragon Ball Heroes Team to allow the to investigate anomalies within the game world timeline to prevent it from collapsing which would allow game enemies to invade the real world if left unchecked.
Not everyone is capable of utilizing the Hero Switch as one must be Hero-Switch compatible to utilize the Hero Switch. Upon encountering a viable candidate that is not the user, the Hero Switch will react by glowing. Beat and Note use this function to find out that Froze is a compatible candidate and after explaining Great Saiyaman 3 needs people like him that are compatible to join the ranks of the Dragon Ball Heroes Team to protect their reality and the game world he agrees to meet with the Hero Master who convinces Froze to join as he a fan of the Hero Master and honored to join his team. This compatibility detection function proves invaluable to aiding them in increasing the ranks of the Dragon Ball Heroes Team.
Video Game Appearances
The Hero Switch was named and first appeared in World Mission.
In Dokkan Battle, the Hero Switch is used by Beat and Note in the SDBHWM Crossover Story Event which partially adapts the plot of World Mission. The portrayal of how Beat and Note manifest their latent powers outside the game world differs between the story mode of World Mission and Dokkan Battleas Leggings, Anne, Froze, and Kagyu are not present in Dokkan Battle and Beat manifests his Great Saiyaman 4 Suit as a result of looking up to Great Saiyaman 3, while in World Mission, it is a built-in feature added by Leggings who intended for the entire DBH team to use but Anne and Great Saiyaman 3 objected.
