"Souchaku" (meaning "Equip") is the series' trademark henshin call, yet in the Philippine and English dubs of Gransazers, they replaced it with "Transform" in Cartoon Network Philippines, GMA, and Hero. There were Gransazers VCDs in the Philippines dubbed in English with the style used in Cartoon Network Philippines, except Episodes 37-40. In Justirisers, Filipino dubbers from Hero Channel and English dubbers from Cartoon Network Philippines used "Transform" while those from GMA had used both "Transform" and "Equip" for the whole series. Meanwhile, in Sazer-X, Filipino dubbers discontinued the use of "Transform" and replaced it with "Equip" in Hero and "Gear Up" in GMA, while the dubbers in Cartoon Network Philippines used "Power Up".
"Dive In" is the series' trademark command for entering inside a particular Star God.
In Justirisers, The Filipino dubbers of both Hero Channel and GMA used "Justiriser" instead of "Riser" to prefix the heroes' names so that Riser Glen was known as Justiriser Glen, Riser Kageri was known as Justiriser Kageri, and Riser Gant was known as Justiriser Gant, although they also used the prefix "Riser" in some episodes.
