Tear apart velociraptor and Godzilla to make a dragon.
Take Batman's wings for the beast.
Leave aside Batman himself for later.
(Later)
...cut off all the spikes - ears, wing pegs (you'd have to see the figure
to know what those are), extra bits on boots and gloves (get lazy and
leave the ones on the fingers, to taste.)
File down remaining yucky bits.
Use spray primer/filler to smoove it out a bit.
Mask off face.
Go into 'Pain Booth' in workshop (really paint booth, but someone got rid
of a strategic 't'), and spray with white automotive paint.
Mask off a Canadian flag, taking advantage of any suitable natural
contours of the figures.
Spray paint it red.
Remove mask _carefully_. Use ordinary brush with automotive paint to
paint over blurred edges and rubbed-off paint work.
Add details using modelling paint/pens. (yellow eyes, white & red lines,
black around boots & gloves, etc...)
At this point, you may notice that the legs are so long, it looks like Clarke's version of Mac. Paint face-mask to be either version, to taste.
