Can batman fight thanos in comics?

The only verified data available identifies Batman as a distinct entity within the comic book canon. No documented comic arc or crossover involving Batman versus Thanos has been cited. Since Batman belongs to the DC universe and Thanos to the Marvel universe, intercompany crossovers are uncommon and, to date, have not included a direct confrontation between these two characters. Without any source confirming such an encounter, the conclusion is that Batman has not fought Thanos in comics.
