When it comes to dealing damage, Alice and Creaturina have entirely different skill sets.
Creaturina was born a predator, she has claws and teeth designed for ripping and tearing. This fact, coupled with her astonishing strength and speed, make technique a minor detail that has no bearing on her ability to lay waste to multiple opponents in seconds. Alice was born a psychopath, the colour of her particular psychopathy serving to make her a cold-blooded killer from a very young age. Though totally fearless, she was still only a slight girl, and had to learn to fight. This she did almost as soon as she could walk, and worked at constantly all her young life. She learned every form of fighting that her parents money could gain her access to, from boxing and fencing, to karate and savate, as well as kendo, archery and all types of marksmanship. If she wasn’t learning formally, she was practicing informally, by, among other pastimes, cage fighting, simple brawling, and shooting her ‘friends’.
This all changed, of course, after Creaturina saved her life by infusing Alice with her, Creaturina’s, own, amazing, alien blood. Creatuies blood not only healed Alice, it made her immortal, and it instantly healed her psychopathy.
