One common theme is the underdog's journey. Usually, the main character starts as a nobody in the mauler wrestling world and has to fight against all odds to reach the top.
For the most part, Invincible Season 2 adheres closely to the comic. There are a few minor tweaks for the sake of TV storytelling, but the core elements remain the same.
Well, the progress of Invincible Season 2 in the comics can be a bit complex. Different issues might cover different amounts of story, and it's not straightforward to measure precisely.
I don't have the exact information. You might want to check the official comic publisher's website or related fan forums for the most up-to-date details.
The distance in Season 2 of Invincible comics is relative. Some storylines have advanced significantly, while others are still unfolding. It's a complex mix.
One great mauler wrestling story is 'The Mauler's Ascent'. It's about a young wrestler in a small town who overcomes numerous challenges to become a renowned mauler wrestler. He battles against tough opponents and also has to deal with internal doubts.
Overall, it has some elements from the comics season 2 but also makes some adjustments for better storytelling and visual presentation. The changes aren't too drastic though.
