TS1 Gesture	N/A	TSFP Gesture	Does an elaborate dance involving some wiggling, waving of the arms, twisting of the knees, and ending with her thrusting one hand up into air. Then she says "Purrrrr. You Tarzan, me Jane. Let me show you how we do it in the jungle."
TS2 Gallery	Raised in the jungle by wolves, the Jungle Queen's sharp intellect is only hampered by her tight thong and lack of language. Captain Ash has promised to make her a duchess if she comes back to Blighty with him.	TSFP Gallery	The Jungle Queen has taken to her new life in the Scottish Highlands like a true native. She has been amazing Captain Ash with her amazing talents for fly fishing and tossing the caber and he’s never had his bagpipes played quite like that before. Och-aye the noo!

The Jungle Queen is a very popular character in TS2 and TSFP. She is one of the characters to have the characteristic TimeSplitters cartoon drawing of themselves. In both TS2 and TSFP, the queen wears jungle clothing (obviously), although in TSFP she looks a bit more like typical royalty.

Story

The Jungle Queen is from the Aztec Jungle, which is evident by the Aztec mission in TS2. However, she is not Queen of the Aztec people, as they attack her along with Captain Ash. She may be the queen of the jungle animals, although this doesn't appear to be true because in the Arcade League challenge Killer Queen she has a Gladiator match with the animals. Because of this, it is not entirely sure if the Jungle Queen is a queen at all (although she was raised by wolves, so she might be queen of the animals indeed). In Future Perfect, the Queen is viewed more as typical royalty than that of a jungle. She now lives in the Scottish Highlands with Captain Ash. Unfortunately for her, she is later kidnapped, although Ash, with the help of Cortez, saves her.

Lady Jayne?

Some think that the Jungle Queen is the same person as Lady Jayne in TimeSplitters. This is very unlikely, as Lady Jayne looks nothing like Jungle Queen. She may an ex-Jungle Queen, but probably not the TS2/TSFP one.
