Thistle Porcupine (シスル・ポーキュパイン, Shisuru Pōkyupain) is one of the Triplex, the executive team of the Red Legion Prominence.
Thistle Porcupine is boisterous and full of energy, which combined with her baby-like voice and quick and masculine speech makes it rather dizzying for those listening. She likes physical contact, as seen when she invited Scarlet Rain to rub her fur-like armor.
She is also adaptable and spontaneous, able to make impromptu, split-second decisions.
Thistle Porcupine in real life is a small girl.
Thistle's net avatar wears a dark red evening dress and has a porcupine's head, complete with spines.
While her name would suggest a duel avatar covered in spines, by default she has a cloak of fur-like armor, a rarity in Brain Burst, which is extremely soft and smooth to the touch. She can also make the fur ripple. However, when agitated, the fur will bunch up dozens of strands at a time into half-meter-long quills.
One of her main methods of attack is to curl up into a ball and bowl over what she wants to destroy.
- Unnamed quill-shooting ability – Thistle Porcupine's quills will be reflexively shot out when surprised, and she has to concentrate to hold them in. Presumably they can also be shot out at will.
- Unnamed fur regeneration ability – This ability allows Thistle Porcupine to regrow her fur after it has been shot out as quills.
- Shape Change – This special move allows her to transform into a nimble porcupine avatar, and can speed her up to at least 1.3 times her base speed.
- Thousand Prickles – A ranged skill of some sort. It is unknown whether this is the quill-shooting ability from above, or whether it is an ability, a special move, or an Incarnate skill.
