This article is about the Astro Gem fusion. You may be looking for the pufferfish monster.

Watermelon Tourmaline is a collaborative character made by sentaiaddict and lupineskyes. She is a fusion of Green and Pink Tourmalines and a member of the Astro Gems. One of the few survivors of the Gem War, the fusion roamed the Earth until she joined the aforementioned group. Watermelon Tourmaline's role is taking care of plants by replacing damaged ones with new ones.


Watermelon Tourmaline is the tallest member of the Astro Gems. She towers over her teammates and often has to bend over to walk through doorways. As a fusion, her appearance is a mixture of both tourmalines. She has light pink skin with dark green wavy hair. Like Pink Tourmaline, it's put up in a high ponytail. The fusion's bangs are long and wavy, slightly revealing her ears. Her face has a slight sharp jawline with droopy pink eyes and a long nose. Watermelon Tourmaline's waist and shoulders are relatively wide when compared with her thin but slightly toned limbs.

She wears a pale yellow tunic with oversized sleeves and a drape in the front and back. The ends are trimmed with a light pink color. The loose collar has a green outline to match with the sash. A white and pink circle sits on Watermelon Tourmaline's left shoulder, mimicking the team's logo. Around her waist is a pink and magenta ribbon sash with a tied bow in the back. She sports light green pants and gladiator sandals, similarly to what Green Tourmaline wears. Her gemstones are located on the left side of her waist and above her sternum.


A bit of Watermelon Tourmaline's personality has been revealed. She is very sweet and cheerful, but can be naive and spacey. The fusion will get distracted very easily, often not paying attention when she needs to. This shouldn't be confused for stupidity as Watermelon Tourmaline is very perspective. Living on Earth for so long has made her knowledgeable about the life on it, especially with plants. Very patient, she takes her time to do tasks despite making her reckless. Watermelon Tourmaline will spring into action when the situation calls for it.


Watermelon Tourmaline has normal Gem abilities.

Watermelon Tourmaline acts as an offense fighter with ranged attacks. She also heavily relies on her abilities to aid her in battle.


  • Ranseur Proficiency: Her weapon, a combination of a gardening scythe and daggers, forms a ranseur. Having a long range allows Watermelon Tourmaline to hit opponents from a distance. It's able to trap weapons between its blades and break it if she twists the weapon. Her weapon can also pierce through some armors and tough surfaces.
  • Gardening: Thanks to Green Tourmaline's expertise, Watermelon Tourmaline has a vast knowledge of plants on Earth. This helps her take care of the plants in the forest.

Unique Abilities

  • Botanical Communication: A combination of Green Tourmaline's plant manipulation and Pink Tourmaline's psychic powers. Watermelon Tourmaline is able to communicate with plants.
  • Plant Manipulation: Watermelon Tourmaline can create and manipulate plant life. Because she's a fusion, this power is increased tenfold.
  • Telepathy: The power to transmit information using her mind. Watermellon Tourmaline can home onto the gems, plants, or people she wants to send her message to. However, she is not able to read minds.
  • Levitation: Watermelon Tourmaline is able to gently float in the air using her mind. She can only lift herself a few inches off the ground and can't fly with it.


Watermelon Tourmaline's past starts with Green and Pink Tourmalines. Both Gems were located on Earth, but had very different roles. Green Tourmaline was a kindergartner and Pink Tourmaline was an aristocratic gem who served Pink Diamond. The two met each other during the start of the Gem War. Green Tourmaline had offered to escort the aristocrat to safety by finding a warp pad. The two had traveled for a while, avoiding various battles between Homeworld and Crystal Gems. During their travels, the two had grown an appreciation for the planet and the life on it. More importantly, they fell in love and wanted to stay together. The two had decided to remain on Earth and become the fusion Watermelon Tourmaline. She survived the aftermath of the war and had lived among the wilderness for thousands of years. Eventually, she stumbled upon a small group of gems. Watermelon Tourmaline later joins them and becomes a member of the Astro Gems.


Green and Pink Tourmalines.

The two tourmalines have a romantic relationship with each other. Their bond has grown over thousands of years and present this through Watermelon Tourmaline. The only time they defuse regularly is when Green Tourmaline works on her garden.
