Gagaga " Gagaga " ( ガガガ " Gagaga " ) is an archetype of DARK Spellcaster and EARTH Warrior monsters used by the protagonist of the " Yu - Gi - Oh ! ZEXAL " anime and manga , Yuma Tsukumo . Their name , " Gagaga " is from either the pronunciation for the Chinese character they use as a crest , which can be pronounced " ga " in Japanese , or the Japanese manga sound effect " ga " which is used for physical impacts , similar to the English " pow " used in comics . This could be because the " Gagaga " monsters use physical attacks in the anime and manga . All " Gagaga " monsters bear a crest of the Chinese character for the first person pronoun ( 我 ) which can be pronounced " wa " or " ga " in Japanese . The crest cannot always be seen on the individual card ' s artwork though , but can be seen in the anime and manga , usually on the monsters ' backs . The male members of the archetype cover the lower part of their faces with scarves , except " Gagaga Child " . The " Gagaga " Spellcasters , " Gagaga Magician " and " Gagaga Girl " , bear a striking similar appearance to " Dark Magician " and " Dark Magician Girl " respectively , monsters used by Yugi Muto in the original " anime " and " manga " . Both " Gagaga " Spellcasters are 3 Level s lower and have 1000 less ATK than their " Dark Magician " counterparts . They are also all DARK monsters , and are often used by Yuma and Yugi in their Duels . The " Gagaga " Spellcasters also share a " " relationship , similar to how the " Dark Magicians " shared a master and apprentice relationship . Playing style . Despite being weak in terms of ATK and DEF , the effects of the " Gagaga " monsters allow them to change their Level s very easily , resulting in quick and easy Xyz Summon s . The effect of " Gagaga Magician " allows him to change his Level from 1 through 8 and the effect of " Gagaga Girl " allows her to copy his Level . This allows them to easily Xyz Summon any generic , Spellcaster specific , or DARK Xyz Monster of Rank s 1 through 8 . " Gagaga Caesar " also helps in this by using his effect to banish a monster in the Graveyard to change the Levels of all face - up " Gagaga " monsters you control to the banished monster ' s Level . This allows them to Xyz Summon any Xyz Monsters above Rank 8 . The greatest additions to the deck are " Gagaga Child " and " Gagaga Sister " . " Child " is capable of Special Summoning itself from the hand if one controls another " Gagaga " monster , fixing a lack of multiple summons for the Deck , and then copy its Level at the cost of the turn ' s Battle Phase , but this cost is mitigated by the strong monsters it can summon if used in conjunction with " Gagaga Magician " . Monsters like " Evilswarm Exciton Knight " , " " , " Castel , the Skyblaster Musketeer " , " Maestroke the Symphony Djinn " , " " , " Divine Dragon Knight Felgrand " , to name a few , are more disruptive than offensive or have a battle related cost themselves , so they can be Summoned with relatively small consequences . " Sister " can Search a " Gagaga " Spell or Trap Card when she is Normal Summoned . Examples include " Gagagashield " or " Gagagarush " . Her true potential , however , lies on searching cards like " Gagaga Academy Emergency Network " and " Gagagarevenge " , which can be used to Special Summon other " Gagaga " monsters , mainly " Magician " to use her own effect that targets another " Gagaga " monster , and makes the Level of that monster and herself the sum of both , those granting access to very powerful monsters up to Rank 10 , even without " Magician " . Since the other " Gagaga " monsters are Level 3 or 4 , this equals to Rank 5 or 6 plays , which can be equally devastating . Also , a lesser known but still effective tactic is to use the " Gagagas " for a Synchro Summon . Only " Gagaga Magician " and " Gagaga Caesar " cannot be used for a Synchro Summon , as stated in their text , but the rest of the archetype can be used , as they don ' t have the same restrictions . With their Level altering abilities and cleaver usage of their support , they can be used to Synchro Summon a variety of Synchro Monsters with ease , making the archetype flexible with other strategies . Even though they cannot be used for the summoning , manipulating " Magician " and " Caeser " abilities , which will in turn manipulate other " Gagagas " , can help fine - tune their Levels to perform a desired Synchro Summoning . While their true strength lies in Xyz Summoning , they are still useful with Synchro Summoning as an alternate strategy . Weaknesses . " Gagaga " monsters however suffer from lack of speed . A good way to mitigate this is to combine " Dododo " monsters in the deck such as " Dododo Warrior " which has a high level and is easily used along " Dododo Witch " and " Dododo Driver " which can perform good combinations , with cards such as " Onomatopaira " that can search key monsters such as " Gagaga Sister " or " Gagaga Magician " ( the former is useful if one discards a Magician and searches a Sister to search a " Gagagarevenge " to Special Summon Magician ) , or cards like " Dodododraw " to draw 2 cards further increasing advantage . " Gagaga Mancer " can also speed up the summoning power by reviving another " Gagaga " monster , though at the cost of not being able to summon any other monsters except " Gagaga " monsters . They also lack raw power for their Levels / Ranks , as the strongest monster of the archetype is the 2100 ATK " Gagaga Head " in terms of printed power ( though " Gagaga Cowboy " can have 2500 ATK , but only when in Attack Position and during your turn ) , which makes them vulnerable to stronger attackers . While " Gagaga Girl ' s " and " Gagaga Mancer ' s " abilities , along with " Gagagatag " , can help mitigate that problem , they will still be left at a disadvantage compared to stronger monsters with the same Levels / Ranks .
