Use Asetone on figurines (not super glue or any other glue type) . Take a small brush or earstick and dip in Asetone, gently apply a bit of Asetone on the broken part, then repeat the process on the other broken part. Join/ hold the two pieces gently together with a light pressure. The asetone reacts as a cement type bond and will joint the parts like if it is "welded" together and will be stronger as new.
Certain Super Glue will use best for buildings.
