Wolverine and the X-Men Season 1 is an animated series directed by Nicholas Filippi and Steven E. Gordon. It is voiced by Steve Blum and Jim Ward and premiered on August 25, 2008. The series tells the story of Wolverine and the X-Men fighting against robots to save the world. It was not aired in 2009.

I researched this and found that you are right. However, it's a little more complicated than that. According to Wikipedia:

In July 2008, the series was pre-sold to Jetix starting August 25, 2008 from Mondays to Thursdays at 4:30 p.m. Unusually, all 26 episodes of the first season were aired in Brazil and Latin America before the series started in any other country. Also, the series airs in Rede Record in Brazil from Mondays to Fridays at 7:00 p.m., starting November 9, 2009. In Mexico, the series aired on Azteca 7.

This would mean the episodes first aired as follows:

• 101: August 25, 2008
• 102: August 26, 2008
• 103: August 27, 2008
• 104: August 28, 2008
• 105: September 1, 2008
• 106: September 2, 2008 and so forth...

However, the original network is listed as Nicktoons, which, according to Wikipedia, premiered the series on January 23, 2009. However, Wikipedia cites a USA Today article that does not actually provide that specific date. Instead, the article just says "which premiere in early 2009". Additionally, the article itself was written on March 18, 2008, meaning that at the time of writing, it referred to a future event.

Regardless, assuming this information is correct, our release dates should also be accurate.

I should also mention that there is a separate list showing English premiere dates starting on September 6, 2008. However, these refer to broadcasts in Canada on YTV (and on CBBC for episodes 20–26).
