This master's thesis deals with the similarities and differences of comics translated into Czech with the originals from North America (USA, Canada). The chosen comics are compared in the translation length, format, cultural and textual transfers and changes, localization of names and nicknames, the presence of neologisms or cultural explanations, and finally adaptation of characters or pictograms. The aim of this thesis is to demonstrate that Czech and North American cultures are very similar, and that the Czech translation and localization of comics, despite common doubts, is high-quality.
