I just realized something. Mewtwo reminds me of Godzilla in several ways:
1. Both characters started out as antagonists, and later anti-heroes.
2. Both went on a destructive rampage.
3. Both are mutants.
4. As a hero, Godzilla takes on many enemy monsters (i.e. King Ghidorah, Gigan, Megalon, and MechaGodzilla) while Mewtwo may take on Genesect in the 16th movie "ExtremeSpeed Genesect."
What else do Mewtwo and Godzilla have in common?
