If you're talking about the low profile slide, it's Grand Viper; Volcanic Viper was Sol's DP.

Her outfit is her SSR, SSBA is her Earth alt’s CA, Delta Clock and Emnity were combined (though, works like Delay in GBF), and her SSBA finish is based on her Summer SSR’s pose (she somehow ended up in a snowy place with her bikini, during Summer.) 1:01 - Beatrix and Embrasque get stronger the more in danger she’s in and she will throw herself at attacks from her allies and rush into fights with no thoughts, head empty (Embrasque likes her because she’s so unlucky and eats causality so she never dies and gained the nickname of ‘Immortal Blue.’) Lore-wise, she’s the only survivor of her well-off family and had a promising future, before bad luck struck, has the closest bond to her Automagod/weapon, and everything she cooks is really sweet (which Embrasque will eat sometimes, because it has a sweet tooth.) Gameplay wise, Delta Clock activates when she uses her command grab and the next usage of Skills will create a Delay effect on hit (Delta Clock will be always active on Skill hits when at low health, but has a cooldown of one Delay per combo.)

After a long time, Queen Beatrix is added to GBVSR, and in Vanilla GBVS was almost +4 years for dont be add it,
