A subcategory of Webcomics involving {{science fiction}}-based plotlines. Pretty much anything that makes regular, plot-intensive use of objects which are scientifically fantastic qualifies here.

We know that [[Analysis/SpeculativeFiction drawing the line]] between these and [[FantasyWebcomics fantasy]] can get a bit [[ScienceFantasy confusing]], so just use your best judgement. However, if it's a modern-day setting with only a few sci-fi elements for humorous effect, then it's probably [[EmbellishedWebcomics Embellished]] rather than sci-fi.
