Alyssa appears as a brown/pinkish red hybrid of a tiger and a spider with six arms. 

She has six bright magenta red eyes; Two main eyes, and four tiny eyes, two on each outer edge of the main two. 

She has a large spider abdomen, but no visible spinnerets. 

Her belly and muzzle are a lighter color than her main body and so are his paw pads. 

Her stripes and thick neck fluff are a tuscan red. 

She has two 'Horns' on her head, which could just as easily be interpreted as palps or chelicerae.
