Is it possible to create animator vs animation from Synfig?

Hello, Although I’m fond of Alan Becker’s animation creative on wrecking desktop.
but I’m very disappoint that he doesn’t have any skills on other software than just Adobe it’s annoying.
Also I never seen anyone make stickman fighting & rampage on desktop from other software at all.
So I’d like to ask is it possible to do with Synfig? Do I need other kinds of softwares to help with Synfig?
or just Synfig is already enough?

I’m interest about:

  1. Making stickman rampaging on Debian XFCE or Xubuntu desktop.
    By convert Flash tutorials from Alan Becker’s to Synfig or other animation, vdo editing software which kind of rough jobs.
    I never seen anyone making for Linux so I want to make one.
  2. Making my character description on desktop along with my video tutorials something like this:
