Is Red still the strongest?

Correct me if I'm wrong, but isn't Red's whole thing being the most powerful?

If not this whole post is a waste of time

Anyways, would Red be able to beat all of the characters after him?

Before I start I want to let y'all know I don't include us (the protagonists)

For example, Leon

He's called the best

But that's Red's thing

If they were to fight, which would keep the title?

Cynthia

I will always believe that she's the strongest champion in the series

Second best trainer all together (Volo beats her)

Could Red defeat her?

I mentioned Volo above

I know he's from the past, but let's say they battle

Would Red fall to the man with seven (technologically eight because Girantina, which is already cheating, cheats again)

Let's go ahead and include the anime

Could Red defeat Ash, who is the one that beat Leon?

There are so many trainers introduced after him that are incredibly strong

Is he still relevant?

Interested in hearing what y'all think!
