5 Times WWE let their Superstars compete for other companies whilst under contract

#3. Hulk Hogan and his toy

Hogan would compete in New Japan multiple times, even as WWF Champion.

Arguably the biggest star in all of wrestling, Hulk Hogan has had success across various promotions, but will perhaps always be known best for his initial run in the WWF. Had Hogan not joined the WWE though, he could've been a big star in Japan, as the Hulkster proved he was a big NJPW fan back in the day when he took on the Great Muta in mid-1993.

For any historians out there, they'll know that at the time of the Muta match, Hogan was the WWF Champion, recently capturing the gold at WrestleMania 9, and things get weirder from there. Post-match, Hogan appeared in a now-infamous segment, describing his own title - the WWF Championship as a toy - claiming the IWGP Heavyweight title was the real prize. It's not too surprising that the Immortal One left the WWF shortly after.
