Growing the Monsters

"Magic wand, make my monster GROW!"

- Rita making one of her monsters grow.

A staple of Power Rangers and Super Sentai in many seasons is the monster growing to giant size after being destroyed, or nearly destroyed, by the Rangers in battle. This would cause the Rangers to summon their zords or mecha to finish off the monster for good. Many monsters required one of the regular villains to make them grow, while others seemed to possess the ability to grow on their own. In some cases the monsters do not grow but rather are shown to pilot their own giant robots, and there are a few cases were neither growing was not needed as the monster was naturally giant sized.

With the exception of S.P.D/Dekaranger, monsters piloting robots is a relatively uncommon occurrence as a whole of the two series in recent years.

Power Rangers

 * Mighty Morphin - During it's three seasons, three different methods were used. See below.
 * Season 1 - Rita would throw her wand to Earth where it would crack the ground releasing steam to enlarge the monster.
 * Season 2 - Lord Zedd would throw a grenade to Earth, where the monster would detonate it. The explosion would release steam to enlarge the monster.
 * Season 3 - Rita and Zedd would bring their staffs together which would send lighting down to the monster to enlarge it.
 * Zeo - Klank would swing Orbus on a thread and throw him at monsters, then Orbus would re-energize and/or enlarge the monster.
 * Turbo - Divatox's Subcraft would fire a pair of torpedoes at the monster which would enlarge it.
 * In Space - The Dark Fortress would fire a green ray from the Satellasers to enlarge the monster.
 * Lost Galaxy - The monster would drink a flask of green liquid. This was later phased out and the monster would grow on its own.
 * Lightspeed Rescue - Jinxer would throw a special card on one of the pieces of debris from the monster which would cause the pieces to form into bats and then reform into the enlarged monster.
 * Time Force - The mutant would remove a patch on its body to expose it's DNA, causing the mutant to enlarge.
 * Wild Force - Toxica would resurrect fallen Orgs and cause them to grow by reciting the spell "Evil spirits of toil and strife, give this fallen Org new life" and firing some magic beans from her staff, which grow into vines that reform and enlarge the fallen Org. This wasn't done on two occasions, as Zen-Aku and Master Org had the power to make themselves grow.
 * Ninja Storm - Lothor's Lairship would launch a Scroll of Empowerment to revive and/or enlarge the monster, several of the main villains piloted robots instead.
 * Dino Thunder - Mesogog uses his hydro-regenerator to revive and/or enlarge his monsters.
 * S.P.D. - Broodwing would release a bat which would bite and enlarge the monster. This was done only once, as the villain would often just use a robot instead. Two other monsters had their own, once-used growth methods.
 * Mystic Force - Koragg would often revive and/or enlarge the monster via a dark spell.
 * Operation Overdrive - With four villain groups came four methods of instigating giant-sized battles. Kamdor would use a sutra to make his monsters grow. Moltor shot a dart at his to make them grow. This was used only once, as he tended to use small monsters or permanently giant robots. Flurious also preferred robots, or monsters that appeared giant sized in the first place. The Fearcats were able to grow on their own by tearing open their bodies, allowing the second body within to emerge and enlarge. The two main Fearcast, Mig and Benglo - perhaps losing this ability once upgraded by Flurious? - typically attacked in a different giant robot in every appearance instead of doing this often. Vulturus, the sole monster created by Thrax, grew by unknown means.
 * Jungle Fury - The Rinshi Beasts would collect fear to make themselves grow
 * R.P.M. - Venjix would activate a "Download" to revive and/or enlarge his robots.
 * Samurai - The Nighloks had two forms, and when destroyed at their regular size they would then unleash the 'Mega-monster' which was a gigantic version of it and had to also be destroyed to finish the Nighlok completely. Moogers, the foot soldiers, were also able to grow.

It has to be from only one store, Imocho, for this to happen, otherwise they shrink. As Grotch found out, expired imo-youkan from Imocho only enlarges the consumer for a short while until he reverts back to original size.

 * The Infershia Pantheon were naturally giants from the start and can revert to their true size at will.
 * GoGo Sentai Boukenger - As there are multiple factions in this season gregariously dubbed "The Negative Syndicate", the growing method really depends on the faction. Some monsters are also already giant.
 * Gajah rarely fought, but when he did, it was either with giant war machines, or with other factions.
 * Starting from Task 16, King Ryuuwon wields a gun that fires a special dart makes a fallen Wicked Dragon come back to life and grow; but usually, their growth was caused by something different and related to the Precious he was hunting. He also commanded Great Evil Dragons in lieu of giant mecha.

 * They can receive a third life, but only when another Gedoushuu gives up part of their life force, which means the donor gives up their second life. However this third life, when activated, is even more powerful than the second.

 * Some Sakamata are born giant.
